Question

In peas, yellow seed color (Y) is dominant to green seed color (y). Which describes an organism that has nonidentical alleles for seed color?

Answer 1

Yy ... i.e. heterozygous condition depicts non identical alleles.

Answer 2

Answer:

Alleles can be defined as alternate form of a same gene.

A organism can have same or identical allele (YY or yy) of a gene which is termed as homozygous condition, or it can have different or non-identical alleles (Yy) for a gene which is termed as heterozygous condition.

Allele which can express itself in heterozygous condition is termed as dominant allele and the allele which can not express itself in heterozygous condition is termed as recessive allele.

Hence, Yy would be the possible genotype with non-identical alleles for seed color.
