Question

Explain monohybrid cross by using a pair of contrasting characters

Answer 1

Answer:

In a monohybrid cross, when homozygous dominant and homozygous recessive parents are crossed, the F1-hybrid obtained would be heterozygous for the trait and would express as the dominant allele.

Thus, the hybrid is heterozygous containing both alternative alleles (Y and y) but only one trait, i.e., yellow colour appeared and green colour trait is suppressed in F1-generation. This shows that yellow seed colour is dominant over the green seed colour trait and both the colour segregates in Fg-generation. This explains Mendel’s law of segregation.
