Suppose that in barley plants, the allele for tall stalks is dominant over short stalks and the allele for wide leaves is dominant over thin leaves. What would be the best way to determine the genotype of a barley plant with a tall stalk and wide leaves?(Hint:a testcross is performed with homozygous recessive for all traits)

Explanation:
Detailed explanation-1: -The allele for tall stalks is dominant over short stalks and the allele for wide leaves is dominant over thin leaves in barley planets. Then the best way to determine the genotype of a barley plant with a tall stalk and wide leaves are to perform a test cross with a barley plant that has a short stalk and thin leaves.
