Let us recall your understanding of concepts of Mendel’s law of inheritance by predicting the possible offspring on a test cross using a Punnett square:
Red tomato fruit (R) is dominant over yellow fruit (r). In a test cross between a homozygous red tomato fruit plant and a tomato plant that has yellow fruit, what would be the genotypes of the parents?
Genotype: ______________
Phenotype: _______________
Questions:
a. What are the genotypes of the offspring?
b. What are the phenotypes?
c. If two of the F1 generation from the above cross were mated, what would be the phenotypes and genotypes of the offspring
