Question

a pea plant that has round seeds has the genotype Rr. it is crossed with a pea plant that has wrinkled seeds and the genotype Rr. What is the probability that the offspring will have wrinkled seeds

Answer 1

50% because both are the same Genotyle dominant wise and recessive wise so it will have a fifty fifty chance of having wrinkled seeds

Answer 2

Answer:

50% or 1/2 of probability of the offspring are the genotype with Rr.

Explanation:

Mendel was known as the father of genetics. He worked on the pea plant Pisum sativum and explained the law of segregation, law of independent assortment and concept of dominance.

The pea plant has round seed with genotype Rr is crossed with pea plant that has genotype Rr. Their cross can be shown as follows:

Rr ( round seeds)   ×         Rr (wrinkled seeds)

Offsprings produced are of genotype Rr, Rr, RR and rr.

Here, the 50% offsprings are wrinkled seeds with genotype Rr.
