Genotype of offsprings:                  Ss    ss

Expected ratio of short to long:      2  :   2 = 1 :  1

The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3

Explanation:

In cats the allele for short hair is dominant over the allele for long hair. (SS or Ss for short hair; ss for long hair).

A short haired male and long haired female have kittens. Eight kittens have short hair and 3 have long hair.

For the parents to have been able to produce long haired offsprings, it means both parents possess one copy each of the recessive traits. Thus we have

Phenotype of parent: A short haired male and long haired female

Genotype of parents:                  Ss     x     ss

Genotype of offsprings:                  Ss    ss

Expected ratio of short to long:      2  :   2 = 1 :  1

Construct an argument about how the physical and biological components in the Chesapeake Bay ecosystem affect the crab populatio
Tamiku [17]

To make an argument about how environmental imbalance affects the ecosystem of the Chesapeake Bay, research on reliable sources on the topic is necessary.

<h3 /><h3>How is the Chesapeake Bay?</h3>

The bay corresponds to the largest ecosystem of estuaries in the USA, being a source of diverse types of habitat for wildlife, with more than 3,600 species of animals and plants.

An example of the environmental imbalance in the area is the commercial and recreational fishing of blue crab, whose population had a significant reduction in 2022.

Therefore, environmental factors and human exploration are responsible for generating such an imbalance, and the development of policies and actions to promote sustainability is essential.
