Question

How many boxes can be found in a Punnett square for a dihybrid cross?

Answer 1

16 boxes.

Step-by-step explanation:

Punnett's painting is undoubtedly one of the main tools for discovering the expected genotypes for a cross. It was created by the English geneticist Reginald Crundall Punnett (1875-1967) and is nothing more than a table in which we separate an individual's possible gametes and make possible combinations between them.

In a nutshell, Punnett's picture is a kind of diagram in which we separate the gametes of one parent in a row and the other in a column and combine rows and columns to observe possible descendants. In each square of the descendants we will be representing a possible crossing of an egg and a sperm. For mono-hybrid features this frame has four boxes, however for di-hybrid features, as the ratio between alleles is higher, the punnett frame has 16 boxes.

Answer 2

The correct answer is 16 boxes.

Step-by-step explanation:

A cross between two different genes or lines that vary in 2 observed traits is the dihybrid cross. By Mendel's law, in between the alleles of both these loci, there is a dominance -recessive relation.

Different combinations of alleles, create a 4 square by 4 square Punnett square. It means there will be four into four alleles in the gametes form 16 offsprings in 16 boxes with genotype of 9:3:3:1

Thus, the correct answer is 16 boxes.
