Question

how do you set up a 16 box Punnett square

Answer 1

Ans:

The Punnett square is the probability diagram that illustrates the possible offspring of a mating.

For a 16 box Punnett square ,

Step 1: Select two parents that are differing two traits

For example, YyRr (Yellow- round seed) × YyRr (Yellow-round seed) are two parents differing in two traits seed shape and seed color.

Step 2: Determination of all the possible allelic combinations in the gametes in each parent.

Step 3: Draw a 4 square by 4 square Punnett square for 4 different combinations of alleles in the gametes of each parent.

Step 4: List the gametes of parent 1 and parent 2 in the two different edge of square.

Step 5: Recombination of alleles into each small square

Step: Determination of phenotypes of each small square and ultimately determine the genotypic and phenotypic ratio.
