Answer:
2[tex]X^BX^b[/tex]:2[tex]X^BY[/tex]
Explanation:
The genotypic ratio of expected of their offspring would be 2[tex]X^BX^b[/tex]:2[tex]X^BY[/tex].
From the illustration, the genotype of the man with male pattern baldness is [tex]X^bY[/tex] while the genotype of the woman without the baldness allele is [tex]X^BX^B[/tex].
Crossing the two genotypes in marriage:
[tex]X^bY[/tex] x [tex]X^BX^B[/tex]
Progeny: [tex]X^BX^b[/tex] [tex]X^BX^b[/tex] [tex]X^BY[/tex] [tex]X^BY[/tex]
Hence, the genotypic ratio of the offspring becomes:
2[tex]X^BX^b[/tex]:2[tex]X^BY[/tex]
