In a different plant species from the example given, flower color is controlled by two genes that contribute equally to pigmentation in the final flower color. the more "r" alleles, the more pigmentation, such that only plants with the genotype crcr drdr have red flowers, and only plants with the genotype cwcw dwdw have white flowers. plants with three "r" alleles produce 75% as much pigmentation as crcr drdr plants and have dark pink flowers. plants with three "w" alleles produce 25% as much pigmentation as crcr drdr plants and have light pink flowers. plants with an equal number of "r" and "w" alleles produce 50% as much pigmentation as crcr drdr plants and have pink flowers. a red flowering plant was mated to a white flowering plant and all of the f1 progeny had pink flowers. these pink flowered f1 plants were allowed to self-fertilize to produce f2 progeny. what is the genotype of the f1 plants that produced pink flowers? (hint: draw punnett squares to determine the f1 and f2 genotypes and phenotypes.)

a) cwcw drdr
b) crcw drdw
c) cwcr drdr
d) crcr dwdw

Nhumans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? in humans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? a, b, ab, and o ab and o a, b, and o a and b
