Matching Match the term to the definition Allele Letter that represents a trait variation Dominant allele a variation of a gene that will produce a certain phenotype, even in the presence of other alleles. Recessive Allele a type of allele which will not be expressed in an individual unless both of the individual's copies of that gene have that particular genotype. Genotype Genetic code for a trait Phenotype physical appearance of a trait homozygous two of the same type of allele heterozygous two different alleles Brown hair is dominant over blonde hair. If a heterozygous brown-haired father is crossed with a homozygous blonde-haired mother, what is the possibility they will have a child who has blonde hair? 25% 50% 100% 0% Genotypes For certain cats:White(H) hair is dominant to black hair.Black (h) hair is recessive.Use this information to write the correct genotypes for the following individuals. Phenotype Genotype Heterozygous Hh Homozygous dominant HH Homozygous recessive hh white-haired purebreed HH Dihybrid Cross Grey eyes (a) are recessive to brown eyes (A). Your mother has grey eyes whilst your father is heterozygous for the trait.Correctly determine the genotypes of all possible offspring for two parents with the genotypes Aa aa.
