I THINK WE
WERE IN THE BATH
FOR TOO LONG!
WE'LL STICK WITH PEAS FOR THE FIRST PROBLEMI
The allele for round peas (R) is dominant
over the allele for wrinkled peas.
The allele for vellow peas (Y) is dominant
over the allele for green peas.
Parent 1 is wrinkled and heterozygous for pea color.
Parent 2 is heterozygous for smoothness and homozygous recessive for
pea color. Work out the possible offspring genotypes and phenotypes
and give the expected probability of each phenotype.
STEP 1) WORK OUT THE PARENT GENOTYPES AND GAMETE ALLELES.
