- A Punnett square is a chart that allows you to easily determine the expected percentage of different genotypes in the offspring of two parents.
- You can predict the percentages of phenotypes in the offspring of this cross from their genotypes.
- A Punnett square can also be used to determine a missing genotype based on the other genotypes involved in a cross.
If one parent has two D alleles for a given gene, and the other parent has two d alleles for the same gene, what will be the genotype in their offspring?
In guinea pigs, smooth coats are dominant over rough coats (s). If an SS guinea pig is crossed with a ss guinea pig, what ratio of smooth coat to rough coat guinea pigs in the offspring would you predict?
If you cross a purebred pea plant with green seeds and a purebred pea plant with yellow seeds what percent of their offspring will have green seeds
If you cross an AABb individual with an Aabb individual, what will the genotype ratio be in the next generation? What will be the phenotype ratio?
If you cross an AABb individual with an Aabb individual, what will the genotype ratio be in the next generation?
What should be assumed to solve a basic genetics problem, unless the problem specifies all the details?
