Mendel was able to study seven traits in all the pea plants in each generation. which of his hypotheses allowed him to analyze each trait separately? (a)if two different alleles for a gene occur together, one of the alleles may be expressed while the other is hidden. (b)when gametes are formed, each gamete carries only one allele for the gene. (c)there are alternate versions of a alleles called genes. (d)for each inherited trait, there is only one copy of the gene that codes for that trait.

A

Explanation:

The study about the seven trait and their inheritance in peas is justified by the hypothesis that if two different allele for a gene occur together, one of the alleles may be expressed while other does not express or suppressed.

The each trait is code by the specific gene. But how these traits are passing with variations to the generations is because of the alleles for the genes that encode traits. These alleles which are responsible for variations ( eg- pea color - green color in homozygous condition and yellow will be expressed in heterozygous conditions) help mendal to study or analyse the seven traits separately.
