Question

In peas, yellow seed color (Y) is dominant to green seed color (y). A homozygous green pea plant is crossed with a heterozygous yellow pea plant. What is the predicted phenotypic ratio of the offspring?

Answer 1

phenotypic and genotypic ratio both are same for this answer i.e. 1:1

Answer 2

Answer:

When the yellow seed coloured pea is crossed with a a green coloured pea plant then the progeny produced will be 75% yellow seeded and 25% green seeded pea plant.

Explanation:

• Pea plant is generally preferred for studying of progeny and the dominance and recessiveness of a character.
• In the above experiment the yellow seeded pea is more dominant and hence it is likely for the producer of progeny to be more of yellow seeded.
• This result is according to the Mendel’s experiment for the occurrence of dominant trait.
• Not only for the pea plant it can be applicable for the most of the living things which produce sexually.
