Question

In humans, curly hair is dominant over straight hair. Which cross below has the correct probabilities listed

Answer 1

Curly hair=C
straight hair=s
CC,Cs
Cs,ss

Answer 2

Answer:

A.a woman heterozygous for hair curl, a man heterozygous for hair curl will produce 25% straight hair, 75% curly hair

Explanation:

a woman heterozygous for hair curl, a man heterozygous for hair curl will produce 25% straight hair, 75% curly hair

using C as the allele for hair curl:

Cc x Cc will produce the following genotypes: CC, Cc, Cc, cc

25% will be homozygous dominant (curly hair)

50% will be heterozygous (curly hair)

25% will be homozygous recessive (straight hair)

combine the curly hair genotypes since the question asked about phenotypes which results in 75% curly and 25% straight.
