Question

R = red flowers
r = white flowers


According to Mendel’s law of dominance, we would expect _________ percent of the offspring to have white flowers.
Responses
A 00
B 2525
C 5050
D 75

Answer 1

According to Mendel’s law of dominance, when considering a monohybrid cross between two heterozygous individuals (Rr x Rr), we can expect the phenotypic ratio of the offspring to be 3:1. This means that 75% of the offspring will have the dominant phenotype (red flowers) and 25% will have the recessive phenotype (white flowers).

Therefore, the correct answer is:

**A 00** (indicating that 25% of the offspring will have white flowers, which is the correct interpretation of the question in relation to the options given).
