This is one giant biology homework question I had to work for lab and I really need help distinguishing between genotypes and phenotypes, please please help! it looks harder than it is!!
suppose a woman who is both homozygous tongue-roller and a non-PTC-taster marries a man who is a heterozygous tongue-roller and is a PTC taster, and they have three children: a homozygous tongue-roller who is also a PTC taster , a heterozygous tongue-roller who is also a taster, and a heterozygous tongue-roller whois a non-taster.
t- non taster
1. what are parent’s genotypes
2. what are parents phenotypes?
3.what are possible gametes?
4.ratios for genotypes of offspring?
5. ratios of phenotypes of offspring?
6. if these parents would have a bunch more children so that they had 12 in all, how many of those 12 would be non taster homozygous for tongue rolling?
