Learning through art: codominant cross can you correctly label the genotypes and phenotypes in this punnett square of a cross that traces human blood types?

That an individual taken at random adventitious from the F2 generation produces wrinkled seeds is 25% and the chance that the same individual outturn yellow seeds is 75%.  The F2 generation against a cross between a plant with yellow-round seeds (YYRR) and a plant with green-wrinkled seeds (yyrr).  

i think that d. wind is the answer.   i missed the question when i answered a. currents.

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 : )
