Choose all the answers that apply. in some plants, pink flowers are dominant over yellow flowers. if marlo crosses two hybrids the ratio of pink to yellow flowers will be 3: 1 50 percent of the offspring will be hybrids none of the offspring will have yellow flowers three-fourths of the offspring will have the same phenotype half of the offspring will be homozygous for flower color

All the answer choices except "none of the offspring will have yellow flowers" and "half of the offspring will be homozygous for flower color" are correct. I conducted a punnet square to help me which gave me the genotypes of PP,Pp,Pp, and pp. Thus, 75% of the flowers have a chance to be pink (phenotype), 50% are hybrids (heterozygous), and a ratio of 3:1 is found. Hope this helped :)

climate change and pollution

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 : )
