In a monohybrid cross between a pure tall pea plant (TT) and a pure dwarf pea plant (tt), state the genotype and phenotype of the F₁ generation and the phenotypic ratio of the F₂ generation.

What is a mutation? State one example in human beings.

Explain sex determination in human beings.

State Mendel's law of independent assortment and name the cross that demonstrates it.

Distinguish between homozygous and heterozygous, and between dominant and recessive.

In pea plants tall (T) is dominant over dwarf (t). A pure tall plant is crossed with a dwarf plant. Give the genotype and phenotype of the F1 and the F2 generations.

Define allele, dominant character and recessive character.
