1. What does dominant mean?What does heterozygous mean?What does homozygous mean?In rabbits the allele for black coat color (B) is dominant over the allele for brown coat (b). What is the genotype ratio and phenotype ratio from a cross between a heterozygous rabbit for black coat and one homozygous for brown coat?What would be the heterozygous alleles?What would be the homozygous alleles? A genetic factor that blocks another. Alleles are different Alleles are the same Bb bb or BBDay 1
2. B = Black coatb = brown coatBb x bbIn rabbits the allele for black coat color (B) is dominant over the allele for brown coat (b). What is the genotype ratio and phenotype ratio from a cross between a heterozygous rabbit for black coat and one homozygous for brown coat?Bbbb Genotype:Bb = 50%bb = 50%Phenotype:Black coat = 50%Brown coat = 50%BbBbbbbb
3. Day 2:The Punnett square below is for a cross between two fruit flies. In fruit flies, the long-wing trait (L) is dominant to the short-wing trait (l). Classify each offspring as homozygous or heterozygous for the trait. Describe the phenotypes of the offspring.LLLLLLLl LlLlHomozygous:______Heterozygous: _______LL = __________________Ll = ___________________What is the % of having long wings? __________What is the % of having short wings? __________ LL Ll long wings long wings 100% 0%
