Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What shows the possible combinations of alleles that can result from a genetic cross?
A
bar graph
B
pie chart
C
punnett square
D
co-dominant graph
Explanation: 

Detailed explanation-1: -A Punnett square is a chart that allows you to determine the expected percentages of different genotypes in the offspring of two parents. A Punnett square allows the prediction of the percentages of phenotypes in the offspring of a cross from known genotypes.

Detailed explanation-2: -The Punnett square is a tabular summary of possible combinations of maternal alleles with paternal alleles. These tables can be used to examine the genotypical outcome probabilities of the offspring of a single trait (allele), or when crossing multiple traits from the parents.

Detailed explanation-3: -The diagram that helps determine the combination of genes that will form by the genetic cross is called Punnett Square.

Detailed explanation-4: -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-5: -A Punnet square shows the genes (represented by letters) in the parents’ gametes along the top and left-hand side of a square and the possible gene combinations in the offspring, within the square. A completed Punnett square gives the probable outcome of a given cross.
