Using the Mendelian model set up, find the P, F1 and F2 of the following. Also write the
possible genotypes and phenotypes of their offspring and the percent chance of each.

A corn with yellow (PP) kernels that was homozygous and dominant for starchy kernels (SS),
and a purple (pp) kernels that was homozygous and recessive for sweet kernels (ss).​

Answer:

Predicting the genotype of offspring

There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other halfs of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.

Explanation:

Phenotype

  • A
  • B
  • AB
  • 0

Possible Genotypes

  • AA or AO
  • BB or BO
  • AB
  • 00

These percentages are determined based on the fact that each of the 4 offspring boxes in a Punnet square is 25% (1 out of 4). As to phenotypes, 75% will be Y and only 25% will be G. These will be the odds everytime a new offspring is conceived by parents with YG genotypes.

hope it helps
