A tall, heterozygous pea plant is crossed with another tall, heterozygous pea plant. What is the probability that an offspring will be a short plant?(1 point)
A)0%
B)25%
C)50%
D)75%
The cross between the two heterozygous tall pea plants is a classic example of a monohybrid cross. In this case, the genotype of the tall pea plant is Tt, where T stands for the dominant tall allele and t stands for the recessive short allele.
When performing a monohybrid cross, there are four possible outcomes for the offspring's genotype: TT, Tt, tT, and tt. Among these possibilities, the only genotype that would result in a short plant is tt.
Now, we need to determine the probability of the offspring inheriting the tt genotype. Since both parent plants are heterozygous (Tt), there is a 50% chance that each parent will pass on the recessive allele (t) to their offspring. Therefore, the probability of an offspring being short (tt) is 50%.
The correct answer is C) 50%.
