Explanation:
Detailed explanation-1: -Specifically, to detect the underlying genotype of an organism with a dominant phenotype, one must do a type of breeding analysis called a test cross. The test cross is another fundamental tool devised by Gregor Mendel.
Detailed explanation-2: -In cats, the allele for short hair (S) is dominant over the allele for long hair (or Angora) (s). A short-haired tomcat is mated with an Angora female. She bears seven kittens; four short-haired and three Angora.
Detailed explanation-3: -In an organism, tall phenotype is dominant over recessive phenotype, and alleles are designated as T and small t, respectively.
