Explanation:
Detailed explanation-1: -The Punnett square is a table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are given. In its simplest form, the Punnett square consists of a square divided into four quadrants.
Detailed explanation-2: -Another example where we can use a punnett square is with blood types. Let’s say a female has a blood type of AB and a male has the blood type of O. Both A and B are considered co-dominant meaning that both the A and the B are present on the females blood cells.
Detailed explanation-3: -A 1:1 phenotypic ratio occurs when there are only two phenotype possibilities as outcomes when organisms are crossed and they both have a 50/50 chance of appearing.
