In a plant of genotype Tt, what is the probability that a gamete will contain gene t?
Answer Details
In a plant of genotype Tt, the T and t are alleles of a gene, and each parent contributes one allele to their offspring. Therefore, the plant can produce two types of gametes - one with the T allele and another with the t allele. Since the plant is heterozygous (Tt), each type of gamete (T or t) has an equal chance of being produced. Thus, the probability of a gamete containing gene t is 1/2 or 50%. Therefore, the answer is/2.
