1. If a man of blood group AB marries a woman of blood group B whose father was type O, what phenotypes could their children be?

2. When two monohybrid round squashes are crossed, the offspring ratio is ¼ flat, ½ oblong, ¼ round. Squash shape is therefore controlled by incomplete dominance. What offspring ratio would you expect from a cross between a plant with oblong fruit and one with round fruit?

3. A gardener crossed a tall pea plant with purple flowers with a dwarf pea plant with white flowers. Both genotypes were homozygous for their traits. What would be the genotype(s) and phenotype(s) of the F1 generation.


4. The gardener crossed 2 of the offspring of the F1 generation from #3. What is the phenotypes and their ratios of the F2 generation?

5. A total of 500 progeny were produced in #4, how many of each phenotype(s) were there?

6. A white eyed female fruit fly was crossed with a red eyed male, what was the potential offspring? Give the phenotypic and genotypic ratios.
