Question

in horses, the allele for straight hair (h) is dominant, and the allele for curly hair (h) is recessive. a horse breeder mates a homozygous dominant mother with a heterozygous male. what is the chance that the offspring will have straight hair? a. 100% b. 75% c. 50% d. 0%

Explanation:

Step1: Determine the genotypes of parents

The homozygous dominant mother has genotype \(HH\). The heterozygous male has genotype \(Hh\).

Step2: Create a Punnett square

	\(H\)	\(h\)
\(H\)	\(HH\)	\(Hh\)

Step3: Analyze the genotypes of offspring

The genotypes of offspring are \(HH\) and \(Hh\). Since \(H\) (straight - hair allele) is dominant, both \(HH\) and \(Hh\) will have straight hair.

Answer:

A. 100%
