The punnet square below represents the result of the cross between two tall pea plants.

t t
t tt tt
t tt tt

t = tall height
t = short height

part a: identify the genotype course & phenotypic ratios of the offspring.

part b: identify two offspring from the punnet square that could produce short pea plants if they were crossed. explain your answer.

Genotype is 1:2:1 (1 Homozygous tall, 2 heterozygous tall, 1 homozygous short)

Phenotype ratio is 3:1

The heterozygous Tt and recessive tt could produce short pea plants if they were crossed.

Explanation:

Genotype is the alleles present for a particular gene. In the Punnett square we can see there will be three tall pea plants and one short pea plant but they can be either homozygous or heterozygous.

While phenotype is the exhibited trait by particular allele that is 3 tall pea plants and one small pea plant.

If Tt and tt are crossed 50 per cent chances of short pea plant is there.
