Question

why is the progeny always tall when a tall pea plant is crossed with a short pea plant?

Answer 1

Answer:

Mendel is known as father of genetics. He has explained the concept of dominance, law of purity of gametes, law of segregation and law of independent assortment.

The dominance concept explains that the trait that can express itself even in heterozygous condition is dominant trait. The trait that can express itself in homozygous condition only is known as recessive trait. The cross between tall and short pea plant produces the tall progeny. The tall progeny is present in heterozygous condition and the tall trait is dominant that express itself and hides the expression of short trait.
