A wild legume with white flowers and long pods is crossed to one with purple flowers and short pods. The F1 offspring are allowed to self-fertilize, and the F2 generation has 301 long purple, 99 short purple, 612 long pink, 195 short pink, 295 long white and 98 short white plants. How are these traits being inherited?

Inheritance of these traits can best be explained by one gene with 3 different alleles.  

Inheritance of these traits can best be explained by one gene with 2 alleles that are incompletely dominant.

Inheritance of these traits can best be explained by two genes, each with 2 alleles. The long pod length allele is completely dominant to the short pod length allele. The white and purple alleles are incompletely dominant.

Inheritance of these traits can best be explained by two genes, each with 2 alleles. The purple allele is completely dominant to the white allele. The long pod allele and short pod alleles are incompletely dominant.

Inheritance of these traits can best be explained by two genes, each with 2 interacting alleles. Each of these genes influences both traits.

Expert Solution

THE ANSWER IS

Inheritance of these traits can best be explained by two genes, each with 2 alleles. The long pod length allele is completely dominant to the short pod length allele. The white and purple alleles are incompletely dominant.

FOR EXPLANATION FIND THE BELOW IMAGE

The pod length is completely dominant hence it exhibits 3:1 ratio segreagation and

as the color is incompletely dominant hence it exhibits 1:2:1 ratio, so when you merged these two the F2 ratio will be

(3:1) x (1:2:1) = 3:6:3:1:2:1.

Find the below explanation for clear idea...

A true-breeding plant with red flowers was crossed with a true-breeding plant with white flowers. The F1 progeny all had a new flower color, pink. The F1 plants were inter-crossed, and produced 44 red, 135 pink, and 61 white flower plants. (4 pts.) What is the most likely mode of inheritance being exhibited in these phenotypes. State your hypothesis and provide your reasoning, which can also include why other modes of inheritance are unlikely (process of elimination). Do not assign...
Populations evolve for many reasons. Suppose there is a population of plants that have either purple flowers or white flowers
Populations evolve for many reasons. Suppose there is a population of plants that have either purple flowers or white flowers, and the allele for purple flowers is dominant. This means that plants with two purple alleles have purple flowers. Plants with one purple allele and one white allele also have purple flowers. Only plants with two white alleles have white flowers. For each event or condition described below, answer the following questions. Which mechanism of evolution is at work? How...
