Read the article to learn more about the disorders that can occur when there is an irregular number of chromosomes. human chromosomal disorders explain how nondisjunction can lead to aneuploidies.

Answers

The formation of the zygote with an abnormal number of the chromosomes is called aneuploidy.

What are the  chromosomes?

We know that the process of reproduction in organisms would involve the passage of the hereditary facts that can be found in the organisms that are under study. This was the focus of the laws that were put forward by Gregor Mendel. He did say that the factors that do control the inhertiance of the organisms are what we call the genes today.

Let us note that the genes that can be found in the organims as we know them are contained in the chromosomes. The chromosomes are also able to be divided as the cell is being divided. In the stages of the cell division, the process by which the chromosomes are separated is called the disjunction.

There are cases where the chromosomes do not separate and this is what we call the nondisjunction of the chromosomes.

Since the chromosomes do not separate accordingly due to nondisjunction, there would be an unusual number of chromosomes and this is called aneuploidy.

The first three strata of the epidermis consists of ______ keratinocytes and the most superficial strata contain ______ keratinocytes.

Answers

The first three strata of the epidermis consists of living keratinocytes and the most superficial strata contain dead keratinocytes.

What is the role of the keratinocytes?

Keratinocytes are the most common cell type in the epidermis, the outermost layer of the skin, accounting for over 90% of all cells. They begin in the epidermis's deepest layer, the stratum basale, and progress to the skin's last barrier layer, the stratum corneum.

The stratum basale (germinatum) is the innermost (deepest) layer of the epidermis, followed by the stratum spinosum, stratum granulosum, stratum lucidum (when present), and the stratum corneum, which is the outermost layer.

in a particular variety of corn, kernel corn is controlled by a single gene with two alleles. the dominant allele results in purple kernels, and the recessive allele results in yellow kernels. a single corncob may contain

75%

50%

Answers

The frequency of recessive yellow beans resulting from a cross between two heterozygous plants is 25%.

What are recessive alleles?

Recessive alleles differ from dominant alleles in not being able to express themselves in heterozygotes. These alleles are only expressed in the phenotype if they are present in pairs, that is, they must be in homozygosity.

With this information, we can conclude that the frequency of recessive yellow beans resulting from a cross between two heterozygous plants is 25%.

There are 19 plants with rough seeds in a population of 100,what is the allele frequency for smooth seeds?

Answers

56.5 is the allele frequency for smooth seeds.

What is allele frequency?

The incidence of a gene variant in a population is represented by the allele frequency. Alleles are different versions of a gene that share the same genetic locus on a chromosome.

Given,

how many plants have tough seed= 19

number of plants overall=100

Frequency of the genotype "plant with rough seed," that is= q²= 19/100=0.19

Consequently, the "rough seed" allele frequency= √0.19= 0.435

We know that the sum of the allele frequencies near the locus is equal to one thanks to the Hardy-Weinberg equation.

Thus, p + q =1

By changing the value of q in the above equation, we obtain -

p+ 0.435 = 1

p= 1-0.435

p= 0.565

P stands for the smooth seed frequency.

A scientist compares the bone structure of the bird wing to that of the bat wing, and observes that the same bones are present in each animal, but with variations in thickness, length, and shape. What evidence of evolution is this an example of

Answers

This is an example of a homologous structure. Homologous structures are anatomical features which have the same organisation but different function (they do different jobs but are “put together” in the exact same way,)

The fact that the bones are the same tells us these organisms have a common ancestor. They have the same structure Because they inherited it from a common ancestor (it has been passed down) who had this structure. This supports evolutions because it proves that organisms inherit features from parents.

But these structures they have variations - like length and shape. This is because they have adapted this structure of suit different environments.

This supports evolution which states that organisms survive dues to the presence of advantageous adaptations.

These homologous structures are an evidence of adaptation.

(formulas: p+q=1 and p²+2pq+q2²=1)
a. What percentage of the population are not Webbed?

Answers

If we have the recessive genotypic frequency, we can calculate the phenotypic frequencies in a population in Hardy-Weinberg equilibrium. The percentage is 82%.

What si the Hardy-Weinberg equilibrium theory?

The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies remain the same through generations in a population that is in equilibrium.  

The allelic frequencies in a locus are represented as p and q. Assuming a diallelic gene,

Allelic frequencies

The frequency of the dominant allele f(X) is pThe frequency of the recessive allele f(x) is q

Genotypic frequencies after one generation are

H0m0zyg0us dominant genotypic frequency,

2pqHeter0zyg0us genotypic frequency,

H0m0zyg0us recessive genotypic frequency.

The addition of the allelic frequencies equals 1

p + q = 1.

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

Available data:

18% of individuals express the recessive trait of Syndactyly

Let us say that the dominant allele is A and the recessive allele is a.

The dominant allele A codes for normal finger.The recessive allele a codes for webbed finger.

Assuming this gene expresses complete dominance,

H0m0zyg0us dominant and heter0zyg0us -AA and Aa- individuals have normal finger.

Their frequency in the population is p² + 2pq.

h0m0zyg0us recessive -aa- individuals have webbed finger.

Their frequency in the population is .

Individuals that express Syndactyly have webbed finger and their genotype is h0m0zyg0us recessive, aa. Their frequency in the population is .

q² = 18% = 0.18

We can get the frequency of individuals with normal fingers by clearing the following equation,

p² + 2pq + q² = 1

p² + 2pq + 0.18 = 1

p² + 2pq = 1 - 0.18

p² + 2pq = 0.82

The frequency of individuals with normal fingers is p² + 2pq = 0.82 = 82%.

The percentage of the population are not Webbed is 82%.

Explanation:

All chromosomes must be completely replicated prior to cell division, a requirement that demands the activation of a sufficient number of appropriately distributed DNA replication origins. Here we investigate how the activity of multiple origins on each chromosome is coordinated to ensure successful replication. We present a stochastic model for whole chromosome replication where the dynamics are based upon the parameters of individual origins. Using this model we demonstrate that mean replication time at any given chromosome position is determined collectively by the parameters of all origins. Combining parameter estimation with extensive simulations we show that there is a range of model parameters consistent with mean replication data, emphasising the need for caution in interpreting such data. In contrast, the replicated-fraction at time points through S phase contains more information than mean replication time data and allowed us to use our model to uniquely estimate many origin parameters. These estimated parameters enable us to make a number of predictions that showed agreement with independent experimental data, confirming that our model has predictive power. In summary, we demonstrate that a stochastic model can recapitulate experimental observations, including those that might be interpreted as deterministic such as ordered origin activation times
