Answer:

a. enzymes have denatured

Explanation:

because enzymes have carbon dioxide to X to temperatature

Answer:

What is the percentage of having a:

healthy male offspring? 100%

female offspring? 100%

2. What is the percentage of having a carrier female offspring? 100%

3. What is the percentage of inheriting the harmful allele?

Male: 0%

Female: 100% carriers of the gene

NOTE: Please see attached for the Punnett Square.

Explanation:

X-linked recessive traits are those traits that can be found on the x chromosome and are represented by a recessive allele. There will be differences in the expression in females and males. For females, with two X chromosomes, both copies of a gene (i.e., one on each X chromosome) must have the trait. If it is only in one of the alleles (heterozygous), the woman will be normal but a carrier of the x-linked condition. On the other hand, for males with one X chromosome, only one copy of a gene must have a mutation. A male with a mutation in a gene on the X chromosome is typically affected by the condition. Because females have two copies of the X chromosome and males have only one X chromosome, X-linked recessive disorders are more common among males than females. However, X-linked recessive traits/disorders can occur in both males and females. One example of these is the red-green colorblindness.

In the question, let us represent the x-linked recessive trait with the allele, X^{a}X

a

. Below are the genotypes and phenotypes:

X^{A}X^{A}X

A

- female, normal

X^{A}X

X^{a} X^{a}X

X

a

- female, with the trait/disorder

X^{A} YX

A

Y - male, normal

X^{a} YX

a

Y - male, with the trait/disorder

Understanding this and using the Punnett Square, you can predict the offspring.
