In Mendel’s experiments, tall pea plants (T) are dominant over dwarf pea plants (t).
Draw a Punnett square board to show the gametes and offspring when both the parents are heterozygous for tallness.

Phenotype
Define the term heredity.
A plant with green pods and smooth seeds with the genotype Ggss will give rise to the following gametes:
Explain the following term : Homozygous
A typical Mendelian dihybrid ratio of F2 generation is 3:1.
How many pairs of contrasting characters in pea plants were studied by Mendel in his experiments?
Do you think Mendel’s laws of inheritance would have been different if the characters that he chose were located on the same chromosome.
In peas, tallness is dominant over dwarfness, and red colour of flowers is dominant over the white colour. When a tall plant bearing red flowers was pollinated with a dwarf plant bearing white flowers, the different phenotypic groups were obtained in the progeny in numbers mentioned against them:
Tall, Red = 138
Tall, White = 132
Dwarf, Red = 136
Dwarf, White = 128
Mention the genotypes of the two parents and of the four offspring types.
