1. For each genotype, indicate whether it is heterozygous (HE) or homozygous (HO) AA _ HO ___ Bb __ HE __ Cc ____ Dd ____ Ee ____ ff __ HO __ GG ____ HH ____ Ii ____ Jj ____ kk ____ Ll ____ Mm ____ nn ____ OO ____ Pp ____ 2. For each of the genotypes below, determine the phenotype. Purple flowers are dominant to white flowers PP _________ Purple ___________ Pp ________ Purple ____________ pp _________ White ____________ Brown eyes are dominant to blue eyes BB ____________________ Bb _____________________ bb _____________________ Round seeds are dominant to wrinkled RR ___________________________ Rr ___________________________ rr ___________________________ Bobtails are recessive (long tails dominant) TT ___________________________ Tt ___________________________ tt ___________________________ 3. For each phenotype, list the genotypes. (Remember to use the letter of the dominant trait) Straight hair is dominant to curly. _____ RR _______ straight _____ Rr _______ straight ______ rr ______ curly Pointed heads are dominan t to round heads. ____________ pointed ____________ pointed ____________ round 4. Set up the square for each of the crosses listed below. The trait being studied is round seeds (dominant ) and wrinkled seeds (recessive) Rr x rr What percentage of the HE HE HE HO HO HE HE HO HE HE HE HO HO Brown Brown Blue Round seeds Round seeds wrinkled Long Long Bob PP Pp pp
