Q6. Guinea pigs, which were homozygous for long, black hair were crossed with ones which were homozygous for short, white hair. All the F1 offspring had short, black hair. (a) Using suitable symbols, draw a genetic diagram showing parents genotypes, to explain this result in F1 offspring. (b) Complete the Punnett square to show the results of interbreeding the F1 offspring. Gametes (c) Complete the following table to show the different phenotypes you would expect in the F2 and their ratio. Phenotype Ratio (d) State the ratio of phenotypes expected in the F2 offspring. (e) Mendel's Second Law of inheritance states that, "during gamete formation the segregation of each gene pair is independent of other pairs." How do the diagrams above prove this law? (AC 2.4).

1. In a particular bird species, the tips of the feathers are tinged with blue, white, or silver. The BB genotype calls for blue-tipped feathers. The WW genotype calls for white-tipped feathers. The BW genotype calls for an intermediate with silver-tipped feathers. A mating occurs between a blue-tipped bird and a white-tipped bird. What types of offspring would be expected? Give the genotypes and phenotypes of the possible offspring and the probability of each. 2. The bird species described in question 5 has an ornamental plumage on its head. The plumage feathers are either flexible or stiff. The allele for flexible plumage is dominant over the allele for stiff plumage. A male who is heterozygous for plumage and has silver-tipped wings mates with a female who has stiff plumage with silver-tipped wings. What types of offspring would be expected from this cross? Give the probability of each. 3. In some cats, the gene for tail length shows incomplete dominance. When a cat with a…

The gene for this trait can be described as Bb (if you forgot why this is so, go back and reread the background information at the beginning of this exercise). A homozygous black female goat (nanny) is crossed with a heterozygous male (billy). 1 What is the genotype of the nanny? What is the phenotype of the nanny?
