Question

If short hair (L) is dominant to long hair (l), then what fraction of the offspring produced by a cross of Ll x ll will have long hair

Answer 1

The answer is 50%.

Step-by-step explanation:

If we cross the two genotypes given in the question as Ll and ll, we can see that 50% of the offspring will have Ll as the genotype and the other 50% will have ll as the genotype.

Since L is the dominant gene, all the Ll genotypes will have long hair as a result of the dominant gene.

I hope this answer helps.
