Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ is a diagram that can be used to predict the possible outcomes of a genetic crossing.
A
Mendel Square
B
Punnett Square
C
Genetic Square
D
Allele Square
Explanation: 

Detailed explanation-1: -Punnett square is a diagram that is used to predict an outcome of a particular cross or breeding experiment. It shows the genotypes two individuals can produce when crossed. A genotype is the genetic makeup of the organism. The phenotype is the trait those genes express.

Detailed explanation-2: -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.

Detailed explanation-3: -Punnett squares are used by geneticists to determine the probability of different offspring genotypes.

Detailed explanation-4: -A Punnett Square is a helpful tool that helps to predict the variations and probabilities that can come from cross breeding. This includes predicting crossing plants, animals, even humans with each other.

Detailed explanation-5: -A genetic cross diagram is a diagram that can be used to show the probability of offspring inheriting certain phenotypical traits.
