recessive allele | An allele that only produces its characteristic phenotype when its paired allele is identical |
sex chromosome | A chromosome that is involved with determining the sex of an organism |
sex linked trait | A trait that is carried only by the male or female parent |
test cross | A genetic cross between a homozygous recessive individual and a corresponding suspected heterozygote to determine the genotype of the latter |
