Question
A cross was carried out between two pea plants showing the contrasting traits of height of the plants. The result of the cross showed 50% parental characters.
(i) Work out the cross with the help of a Punnett square.
(ii) Name the type of the cross carried out.
Solution
(ii) The type of cross carried out here is a test cross. It is a cross in which an individual with an unknown dominant phenotype is crossed with an individual (parent) homozygous recessive for that trait.
