The Punnett square is not found here but, according to data, these genetic traits involve the expression of two different genes (proportion 1/16 in double recessive).

What is a Punnett square?

A Punnett square is a diagram used in genetics to calculate the genotypic proportion from a given genetic cross.

Two different genes may generate 16 genetic (allelic) combinations in a Punnett square.

Moreover, fur color and eye color are phenotypic traits that depend on the recessive-dominance allele relationships received in offspring.

In conclusion, the Punnett square is not found here but, according to data, these genetic traits involve the expression of two different genes (proportion 1/16 in double recessive).

Which of the following best describes why in general there are more hares in the ecosystem than foxes.

In 1945 there was a major event that caused the number of hares to dramatically increase. That is why there continues to be more hares than foxes here.

Hares are a lot smaller than the foxes, so more of them can fit into different niches. They can hide better in all of the bushes and behind rocks.

This is because if only 10% of the energy gets passed on to the next trophic level, then you need to have more lower level animals available to support the animals higher up the food chain. The fox must eat several hares to gain enough energy for growth and development

Answers

One of the greatest economic consequences of agriculture in recent years is overfishing.

Economic consequences of agriculture

Agricultural activities have led to overfishing.

Overfishing leads to a reduction in fish biodiversity and the loss of important species that could serve as food, drugs, or industrial materials for the use of man or his livestock.

Overfishing means that there will not be enough fish for humans in the nearest future. This may result in a malnourished human population.

Overfishing can also cause ecological problems such as disruption to food chains.

Natural selection forces either select for or against traits. Traits that aid organisms in adapting are selected for, while those that do not aid in adaptation are selected against.

Under ideal conditions, how do allele frequencies change over time?
A. The frequency of the recessive allele increases in each generation.
B. The allele frequency does not change from one generation to the
next.
C. The frequency of the dominant allele increases in each generation.
O D. The alleles eventually reach a 50/50 balance.

Answers

The frequency of the dominant allele increases in each generation. Thus, the correct option is C.

What is natural selection?

Natural selection is a process in which more environment-adapted organisms tend to survive and reproduce more frequently than less environment-adapted ones.

Because rare alleles are typically found in heterozygotes, the initial increase in frequency of a rare, advantageous, dominant allele is faster than that of a rare, advantageous, recessive allele. Therefore, natural selection won't be able to "see" a new recessive mutation until it is prevalent enough to manifest in homozygotes.

Once a population is in Hardy-Weinberg equilibrium, its frequency distribution won't vary from generation to generation.
