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

part a: identify the genotypes & phenotypic ratios of the offspring (2 points)

part b: identify two offspring from the punnet square that could produce short pea plants if they were crossed. explain your answer (2 points)

Part a:

The phenotypic ration will be 4:0. This is because all the offsprins will be taal,

The genotypic ration will be 2:2. This is because there will be a 50% chance of the offsprings to be homozygous tall. There is also a 50% chance for the offsprings to be heterozygous tall.

Part b:

When two heterozygotes will be crossed, there will be 25% chance that the offspring could be short pea plant.
