4:12 5. Set up the punnett square for each of the crosses listed below. The characteristic being studied is seed texture round seeds (dominant) and wrinkled seeds (recessive). Rr x rr Rr x Rr RR x Rr Tall: % Complete the punnett squares below using the given information. 6. A TT (tall) plant is crossed with a tt (short plant). Which trait is dominant? Give the expected probabilities for each genotype and phenotype. TT: Tt: Short: Previous % % tt: What percentage of the offspring would you expect be round? Wrinkled? ZOOM + What percentage of the offspring would you expect be round?_____ Wrinkled? What percentage of the offspring would you expect be round? Wrinkled? % 7.

16. A test cross is done to determine:   the genotype of an individual showing a known phenotype   the phenotype of an individual with a known genotype   the genotype of an individual showing a dominant phenotype   if an individual showing a known phenotype is homozygous or heterozygous

V. Two Gene Pairs (Extra Credit) 1... A. In peas, the allele for tall plants (T) is dominant over the allele for short plants (t). The allele for smooth peas (S) is dominant over the allele for wrinkled peas (s). Use this information to cross the following parents. I 1. heterozygous tall and smooth X heterozygous tall and smooth 2. heterozygous tall, wrinkled X short, wrinkled AL.

2. Cross a Brown and White Spotted Cow with a White Cow. What is the percentage of the genotype and phenotype of the offspring? What type of punnett square will you be using for this cross? Codomnent BB WW Parents: Genotypes: P1 x P2 Offspring: Genotype: Phenotype:

1. Create a Punnett square showing the genotypes of the offspring for a homozygous dominant purple plant crossed with a heterozygous purple plant. Be sure to include the genotype and phenotype ratios. 2. In a population of snapdragons, two heterozygous pink individuals mate. What is the percent chance that a PINK plant will be the offspring? Include a Punnett square to show your work. What type of dominance does this plant show? 3. There was a mix of up children in the maternity ward of a hospital. The children in question and their blood types are listed below. Child 1: type A (genotype I^I^ or I^i) Child 2: type B (genotype 181³ or 1³i) Child 3: type AB (genotype IIB) Child 4: type O (genotype ii) a. Which child or children could belong to a couple having AB and O blood types? Show your work. b. Based on the previous question, is it possible to prove paternity based on blood types? Explain.
