Explain the Law of Dominance using a monohybrid cross.
Design a test-cross.
Using a Punnett square, workout the distribution of phenotypic features in the first filial generation after a cross between a homozygous female and a heterozygous male for a single locus.
When a cross is made between tall plant with yellow seeds (TtYy) and tall plant with green seed (Ttyy), what proportions of phenotype in the offspring could be expected to be:
- Tall and green.
- Dwarf and green.
Two heterozygous parents are crossed. If the two loci are linked, what would be the distribution of phenotypic features in the F1 generation for a dihybrid cross?
