In pea plants, flowers are either white or purple; the purple color is produced by pigments called anthocyanins. the production of anthocyanins is a two-step process: the first is controlled by the c gene and the second by the p gene. the genes are not linked and both must produce functional proteins for anthocyanin to be expressed. for each gene, the dominant (c and p) alleles produce functional proteins. you cross two pea plants, each with the genotype ccpp. what proportion of their offspring will have white flowers?

I should remember that it is important to show uppercase and lower case in genetics, to differenciate the dominant alleles from the recessive ones.

If we cross two ccpp genotypes (all lowercase = all recessive alleles that produce unfunctionnal proteins) we will obtain 100% of white pea plants because all the offspring will have the ccpp genotype (without any dominant allele producing functionnal protein).

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
