Answer 2

The geometrical device that helps to find out the possible combination of male and female gametes is called Punnett square and given by Reginald C. Punnett .

Explanation:

• Punnett square is used to find possible genotypes of a particular cross.
• Reginald C. Punnett ( British geneticist) devised this approach.
• It is mainly a diagram which helps to assume the probability of offspring having a particular genotype.  
• Two types of Punnett square are generally used;

        monohybrid cross and dihybrid cross.

• In monohybrid cross, single traits are being followed and Punnett square is small, with four boxes.
• In dihybrid cross, two traits are being followed and Punnett square is large, with 16 boxes.
