Use the punnett square below to answer the following questions r = round ears r= pointy ears 1 how many offspring will have round ears? what percentage of offspring will have 3pointy how many offspring will be carriers of the 4pointy ear based on the allele combination rr, both parents are considered to

0.75

0.26

0.5

Round ears dominant i think

I think for the first square its RR, second square Rr, third square Rr, and the fourth square rr. Usually they use uppercase for the dominant trait and lowercase for recessive so Im assuming number one would be abount 75%? the second one probably around 25% ns tho, Idk the last one But i hope this helps you, have a wonderul day/evening. :)

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.
