A test cross to determine the genotype of a green-colored seed would best be represented by . a. Yy x Yy
b. YY x YY
c. YY x Yy
d. Yy x yy

d. Yy x yy

Explanation:

In Mendelian inheritance, a TEST CROSS is a cross used to determine the actual genotype of a dominant phenotype. The test cross is usually performed between the unknown genotype and a recessive genotype. If all the offsprings are dominant, the unknown genotype is the same allele but if the offsprings are half dominant and half recessive, the unknown genotype is HETEROZYGOUS.

In this case, a test cross to determine the genotype of a green-colored seed would best be represented by Yy × yy because a test cross must include a recessive genotype, which is "yy" in this case.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
