The allele (aa, aa, or aa) combinations are achieved through what process? question 1 options: meiosis mitosis interphase mendelian question 2 each box in a monhybrid cross is worth how much percentage? question 2 options: 25% 50% 75% 100% question 3 if you cross pp with pp what is the percentage that the offspring will have at dominate trait? question 3 options: 25% 50% 75% 100% question 4 in incomplete dominance lets say we cross a red (rr) x with a white (ww) flower. what is the percentage we will get pink (rw) question 4 options: 25% 50% 75% 100% question 5 which is not one of the possibilities that could arise through independent assortment of tthh question 5 options: th th ht tt question 6 which combination is the rarest to have? question 6 options: aabb aabb aabb aabb question 7 what is the percentage the seeds will be round and yellow? question 7 options: 6% 19% 25% 56%

Answer 1-

Mendelian

The different allelic combinations are made by the process of mendelian inheritance. This happens before cell division.

Answer 2-

25%

In a monohybrid cross, there are four boxes, and thus each box denotes 25% share.

Answer 3-

75%

The cross between Pp and Pp will look like the image shared below. Here, PP and Pp will show dominant trait. Since, it is 3 out of 4 boxes, it will be 75%.

Answer 4-

100

The punnett square for this cross RR and WW is shown below. Since all the offsprings are RW, therefore it is 100% pink flowers.

Answer 5-

Tt

Since it is a case of dihybrid cross, the gametes formed from TtHh would contain both the alleles. The possible gametes would be TH, Th, tH and th.

Answer 6-

aabb

In any dihybrid cross with dominant alleles, the probability of getting aabb would be the least.

Answer 7-

56%

In a cross AaBb and AaBb, the probability of getting both dominant traits- round and yellow, would be 56%

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 : )
