‘Test cross’ app provides an in-depth and exclusive information about the Mendelian cross with garden pea plant performed to know the genotype of the individuals of F1 generation.

‘Test cross’ app explains the very important cross between the F1 individual and the recessive parent. This cross is termed as 'Test cross' and is done to find out whether the F1 individuals are homozygous or heterozygous.

Let us explore the offerings of the ‘Test cross’ app. The user gets to interact with the 2D models of the particular traits of pea plant. The trait taken here is the 'flower colour'. The user can explore the 2D models of the flowers through the ‘zoom in’ and ‘zoom out’ options. The app 'Test cross' gives an opportunity to the user to simulate the steps of the Mendelian cross. The user can simulate the formation of types of gametes and can perform the cross all by himself to get a better comprehension of the principle of the 'Test cross'. The placement of gametes in the Punnett square to obtain the individuals of the next generation is something any user would enjoy.
