A man who has male pattern baldness (X^bY) marries a woman who does not carry the allele (X^BX^B). What genotypic ratios would b

JulijaS [17]

Answer:

2 $X^BX^b$ :2 $X^BY$

Explanation:

The genotypic ratio of expected of their offspring would be 2 $X^BX^b$ :2 $X^BY$ .

From the illustration, the genotype of the man with male pattern baldness is $X^bY$ while the genotype of the woman without the baldness allele is $X^BX^B$ .

Crossing the two genotypes in marriage:

$X^bY$ x $X^BX^B$

Progeny: $X^BX^b$ $X^BX^b$ $X^BY$ $X^BY$

Hence, the genotypic ratio of the offspring becomes:

2 $X^BX^b$ :2 $X^BY$
