What is the benefit of living on Island A chinstrap penguins

Living on island enables chinstrap penguins to get their meal easily and enjoy diving.

Explanation:

Chinstrap penguins are the abundant penguins. They have a narrow black band under their head. They are found many islands. Island is surrounded by water from all sides. These penguins are carnivorous who feed on other fish, crabs, etc. Penguins can easily find their meal on the islands. The chinstrap penguins enjoy diving.

That is why they form their colonies near water bodies mainly islands. Their feathers are tightly packed which makes them waterproof and it protects them from winter.

answer; i believe that the correct answer is ; males are hemizygous for the x chromosome;

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.
