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 is 100%.

Step-by-step explanation:

In Mendel's experiments with pea plants, he found that smooth pods are dominant to indented pods, green pods are dominant to yellow pods, and yellow seeds are dominant to green seeds. To determine the probability of having offspring with a smooth and yellow pod and either four green or four yellow seeds, we can use the principles of Mendelian genetics and perform a Punnett square analysis.

First, let's assign the dominant allele for smooth pod as 'S' and the recessive allele for indented pod as 's'. Similarly, let's assign the dominant allele for yellow seed as 'Y' and the recessive allele for green seed as 'y'.

The cross between two individuals with smooth and yellow pods would have the genotype SSYY. To have offspring with either four green or four yellow seeds, we would need to cross it with an individual homozygous recessive for seed color, yy. This would result in 100% hybrid offspring with a smooth and yellow pod and either four green or four yellow seeds.
