3x3 punnett square.
If we look at our Punnett square, we find that there is a 1/4 chance of offspring being homozygous dominant for smooth kernels (KK) and a 2/4 chance of that the offspring will be heterozygous (Kk) for smooth kernels. Combined, we find that there is a 3/4 chance that the offspring will have smooth kernels. The correct answer is. 3/4
The Punnett square is a table or checkboard grid that is used to determine all possible genotypes from a particular cross.

Make a “key” for the trait, identify the parents involved in the cross and the gametes each parents produces. Show the Punnett square and give the ratio of both genotype and phenotype. Before you begin….Define the following terms from your notes….A two-trait Punnett Square has 16 boxes. The probability of a cross producing a genotype in any box is 1 in 16. If the same genotype is present in two boxes, its probability of occurring doubles to 1/8 (1/16 + 1/16). If one of the parents is a homozygote for one or more traits, the Punnett Square still contains the same number of boxes, but the ... Mar 24, 2015 · The Punnett Square.
