According to evolutionary theory ,natural selection is linked to reproductive fitness, which is present only in the earlier part of adulthood.

<h3>What is evolutionary theory of aging?</h3>

Evolutionary theory of aging is a theory that state the reason there is increase in mortality with age. As person grow older, less lifetime fertility remains, Therefore, continued survival lead to a reduced. reproductive fitness.

Therefore, According to evolutionary theory ,natural selection is linked to reproductive fitness, which is present only in the earlier part of adulthood.

The following two genotypes are crossed: AaBbCc X+Xr AaBBcc X+Y, where a, b, and c represent alleles of autosomal genes and X+an
choli [55]

Answer:

1/64

Explanation:

The following genotypes were crossed: AaBbCc X+Xr and AaBBcc X+Y

If we asume that the autosomal genes are in different chromosomes, then they will assort independently during meiosis and gametogenesis. In that case, we can use the Multiplication Rule of Probability to obtain the probability of having a specific genotype in the progeny.<u> This rule states that when two or more events are independent, the probability of all them happening at the same time will be the result of the multiplication of the individual probabilities of each event.</u>

<u />

We can separate each gene in the cross to determine the genotypic ratios in the offspring, and then multiply the probabilities of the aaBbCc X+X+ genotypes to obtain the overall probability of having progeny with that genotype.

<h3><u>Aa x Aa </u></h3>

1/4 AA

2/4 Aa

1/4 aa

<h3><u>Bb x BB </u></h3>

1/2 BB

1/2 Bb

<h3><u>Cc x cc </u></h3>

1/2 Cc

1/2 cc

<h3><u> X+Xr x X+Y</u></h3>

1/4  X+X+

1/4  X+Y

1/4  X+Xr

1/4  XrY

The probability of having offspring with the aaBbCc X+X+ genotype will be: 1/4 × 1/2  × 1/2  × 1/4 = 1/64
