Question

In his studies on pea plants, Mendel found that smooth pods are dominant to indented pods, green pods are dominant to yellow pods, and yellow seeds are dominant to green seeds. In a cross between two a individuals, what is the probability of having offspring with a smooth and yellow pod and either four green or four yellow seeds.

Answer 1

The probability of having offspring with a smooth and yellow pod and either four green or four yellow seeds in a cross between two individuals is 100%.

Step-by-step explanation:

In a cross between two individuals, each with a smooth and yellow pod, and either four green or four yellow seeds, we can use the principles of Mendelian genetics to determine the probability of obtaining such offspring.

First, we need to consider the inheritance patterns for each trait. Smooth pods and yellow seeds are both dominant traits. So, if both parents have smooth and yellow pods, and either four green or four yellow seeds, they would have the genotypes SSYYGG or SSYYgg, respectively.

When we cross two individuals with the genotype SSYYGG, all offspring will have smooth and yellow pods and four green seeds. Similarly, when we cross two individuals with the genotype SSYYgg, all offspring will have smooth and yellow pods and four yellow seeds. So, the probability of having offspring with a smooth and yellow pod and either four green or four yellow seeds is 100%.
