Two linked loci have a recombination frequency of 5%. A series of crosses is performed. The P generation includes an individual that is homozygous dominant for trait 1 and homozygous recessive for trait 2. The second individual is homozygous recessive for trait 1 and homozygous dominant for trait 2. The F1 generation is crossed with individuals that are homozygous recessive for both traits. If 400 F2 offspring are produced, how many offspring with each phenotype are expected? Fill in the table below with your answers. Phenotype Number of Offspring Predicted Recessive 1, Recessive 2 Dominant 1, Dominant 2 Recessive 1, Dominant 2 Dominant 1, Recessive 2

Question
- Two linked loci have a recombination frequency of 5%. A series of crosses is performed. The P generation includes an individual that is homozygous dominant for trait 1 and homozygous recessive for trait 2. The second individual is homozygous recessive for trait 1 and homozygous dominant for trait 2. The F1 generation is crossed with individuals that are homozygous recessive for both traits. If 400 F2 offspring are produced, how many offspring with each phenotype are expected? Fill in the table below with your answers.
