Lauren Allen Lab Monday at 6 PM Mendelian Genetics Pre-Lab 1. A reciprocal cross is a cross in which the female may begin with the dominant genotype and the male with the recessive genotype and then another cross is done where the female is now the recessive genotype and the male is the dominant. 2. The F1 is filial to the P and the F2 is filial to the F1 generation. This is because P is the parent of F1 and F1 is the parent of F2. 3. If the trait is dominant it’s more likely to show up in a cross between two homozygous recessive and homozygous dominant individuals as a phenotype because all you need is one dominant allele. The homozygous dominant genotype, however, requires two dominant alleles. If the trait is recessive it’s less likely to show up in a cross like this because you need two recessive alleles for both the recessive phenotype and genotype. 4. A monohybrid cross is a cross in which only one characteristic is being tested as a hybrid cross. 5.
