Answer» Dihybrid Cross - A cross which involves plants with two pairs of contrasting characters\tConsider a cross of pea plants with round and yellow seeds and plants with wrinkled and green seeds. In this cross, the two pairs of characters involved are seed shape and seed colour.\tThe capital letter R is used to denote round-shaped seeds and capital Y to denote yellow-coloured seeds. The genotype of the parent plant is RRYY. The other parent has wrinkled seeds which are green in colour. The letter small r denotes wrinkled seeds and small y denotes green-coloured seeds. The genotype of the parent is rryy. The two parent plants are then crossed, RRYY × rryy. When two characteristics are transferred simultaneously it is called dihybrid cross |
