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.

The P generation has yellow and green seeds.

The F1 generation has all yellow seeds.

The F2 generation has yellow and green seeds.

Explanation:

A dominant gene is the one which is able to express itself even in the presence of another recessive gene.

Therefore, since yellow is dominant over the green, in the heterozygous condition, the plant will have a yellow color.

Now considering the parental (P) generation to be true breeding as given in the question, the cross would be as follows:

P     YY (yellow plant) X yy (green plant)

F1    Yy (yellow plant)

F2    YY Yy Yy yy

where YY and Yy are yellow plants and yy is a green plant.

See the attached image of the Punnett square for the cross.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
