ApplicationIntroductory
What are the possible genotypes of children from a cross between a homozygous dominant female with freckles (FF) and a homozygous recessive male without freckles (ff)?
The possible genotypes of children from a cross between a homozygous dominant female with freckles (FF) and a homozygous recessive male without freckles (ff) are all heterozygous (Ff).
Key points
- Female parent genotype: FF (homozygous dominant for freckles)
- Male parent genotype: ff (homozygous recessive for no freckles)
- All offspring will be heterozygous (Ff) and will have freckles.
