Answer #1

Answer : a) Heterozygous

In mendalian experiment the yellow pea colour is a dominant trait (Y) and green pea colour is recessive (y). Here the yellow pea is self pollinated to produce both green and yellow peas.

If the parent yellow pea is homozygous (YY), all of the offspring will be yellow pea since the yellow pea is a dominant trait.

The parent cannot be homozygous recessive since it is given that the parent is yellow pea ( dominant trait)

Hence only the Heterozygous parent Yy (yellow pea) can produce both yellow pea and green pea offsprings.
