Question

In pea plants, yellow seed color is dominant and green seed color is recessive. What will the generations look like? Assume that Mendel’s method of crossing two true breeding parents with opposite traits is followed. Check all that apply.


The P generation has all yellow seeds.


The P generation has all green seeds.


The P generation has yellow and green seeds.


The F1 generation has yellow and green seeds.


The F1 generation has all yellow seeds.


The F2 generation has all green seeds.


The F2 generation has yellow and green seeds.

Answer 1

Because Mendelian laws are followed, the parents have to be true-breeders meaning both have to be homozygous for all traits. So, I would mark "The P generation has yellow and green seeds." Then, because Yellow is dominant, all the F1 generation will be heterozygous and yellow. So, I would check "The F1 generation has all yellow seeds." Now, after the F1 generation breeds, there are bound to be yellow and green offspring because 4 different types of gametes are produced, at least by the known F1 offspring. So, I would also check "The F2 generation has yellow and green seeds."

Hope this helps!
