The seeds from Mendel’s plants can produce tall, round and yellow dominant traits and their genes are independently assorted. The recessive genotypes dd, ww, and gg produce dwarf plants with wrinkled and green seeds respectively. (a) If a pure tall, wrinkled, yellow variety is crossed with a pure dwarf, round, green variety, what pehnotypic ratio is expected in the F1 and F2? (b) What percentage of the F2 is expected to be of genotype DdWWgg?

1. (a) F1 is all tall round and yellow, F2 is 27 tall, round, yellow: 9 tall, round, green: 3 tall wrinkled yellow: 3 dwarf round yellow: 1 tall, wrinkled, green: 1 dwarf, round, green:1 dwarf wrinkled yellow: 1 dwarf wrinkled green (b) 1/64
