In mendel's experiments on seed color in pea plants, when a dominant yellow seed-bearing plant was crossed with a recessive green seed-bearing plant, what was the approximate phenotypic ratio among the f 2 generation?

3 yellow : 1 green.

Explanation:

The Mendel is known as the father of genetics and explains the laws of heredity. Mendel explains the inheritance pattern in the pea plant and also explained the concept of dominance.

The dominant trait will express itself even in heterozygous condition whereas recessive trait unable to express itself and expressible in homozygous recessive condition only. The cross between the yellow dominant seed ( YY) when crossed with green seed (yy), the F 1 generation is Yy. Their cross shows the F2 generations as shown below.

Parents  Yy     ×   Yy

F2 generation YY, Yy, Yy ( yellow) and yy (green).

Thus, the answer is  3 yellow : 1 green.

i really wish i could answer this question for you
