How do you determine the genotype?

BABY STEPS:
  1. determine the genotypes of the parent organisms.
  2. write down your "cross" (mating)
  3. draw a p-square.
  4. 4. "
  5. determine the possible genotypes of the offspring by filling in the p-square.
  6. summarize results (genotypes & phenotypes of offspring)
  7. bask in the glow of your accomplishment !

Herein, what is a genotype in biology?

Definition. noun, plural: genotypes. (1) (genetics) The entire set of genes in an organism. (2) (genetics) A set of alleles that determines the expression of a particular characteristic or trait (phenotype) (3) (zoology) The genetic makeup of an individual or taxon.

What are the three genotypes?

There are three available genotypes, PP (homozygous dominant), Pp (heterozygous), and pp (homozygous recessive). All three have different genotypes but the first two have the same phenotype (purple) as distinct from the third (white).

What is the genotype of the parents?

A dominant allele is denoted by a capital letter (A versus a). Since each parent provides one allele, the possible combinations are: AA, Aa, and aa. Offspring whose genotype is either AA or Aa will have the dominant trait expressed phenotypically, while aa individuals express the recessive trait.
