A cross was carried out between two pea plants showing the contrasting traits of heightofthe plant. The result ofthe cross showed50% ofparental characters.

(i) Work out the cross with the help of a punnett square.

(ii) Name the type of the cross carried out.

i.

When we cross a heterozygous tall plant(Tt) with a homozygous recessive plant(tt) we will get 50% parent character in the progeny that is-

50% tall heterozygous(Tt)

50% homozygous recessive (tt)

ii. The type of cross carried out here is ‘ Test cross’. As test cross is a cross in which an unknown dominant phenotype plant is cross with a homozygous recessive phenotype plant.
