Tasting involves many different cell-signaling processes that ultimately generate nerve signals transduced by membrane depolarization. sweet tastes result in pip2 hydrolysis, while salty tastes allow sodium ions to directly alter the membrane potential. what can you deduce about the signaling mechanisms for sweet and salty?
that is true. its like when a horse goes into heat. *ready to mate*
the correct answer would be rr.
in a monohybrid cross, the phenotype ratio of 3: 1 is obtained only when both the parents are heterozygous for the trait.
in this condition, the heterozygous genotype would be rr. the phenotype of both the parents would be round seeds (r) as the round is a dominant trait.
the cross of these parents would produce offspring with three types of genotypes rr, rr, and rr in ratio 1: 2: 1.
thus, the phenotypic ratio would come out to be 3 (round seed): 1 (wrinkled seed).
