The allele for a widow’s peak has complete dominance over the allele for a straight hairline (w). What is the probability of two parents heterogeneous for a widow’s peak (Ww) having an offspring without a widow’s peak? 25 percent 0 percent 50 percent 75 percent

Sagot :

Ww Ww  combinations  WW  Ww    50%

Answer:

Option A

Explanation:

It is given that allele for a widow’s peak (W) is completely dominance over the allele for a straight hairline (w).

Two heterogeneous parents are crossed with genotype (Ww)

Therefore following offspring are produced-

Ww * Ww

WW

Ww

Ww

ww

Thus, out of four only one offspring with genotype (ww) will be without a widow’s peak.

Thus, the probability of having an offspring without a widow’s peak

[tex]\frac{1}{4} * 100\\= 25[/tex]%

Thus, option A is correct
