Two normal parents have three children. One of the children has Sickle Cell anemia. Sickle cell anemia displays this type of inheritance pattern.
What is autosomal recessive?

In rabbits, four different fur color alleles are possible, but they are controlled by only one gene. What is this form of inheritance called?
What is multiple alleles?

In a certain species of insect, black wings are dominant (B) and brown wings are recessive (b). Two heterozygous insects are mated. What is the genotype ratio results?
What is 1 BB: 2 Bb: 1 bb?

The separation of chromatids in Anaphase II demonstrates which of Mendel's Laws?
What is the Law of Segregation?

Mr. Smith is a dog breeder who specializes in Dalmations. Unfortunately, there is a common recessive defect among this breed that results in deafness. Mr. Smith has a new male dog that he would like to use for breeding purposes, but he suspects the male dog may carry the deafness gene. What kind of a breeding test cross would be likely to help him figure out the male's genotype?
If he crossed the male with a deaf female dog, and any of the puppies are deaf, then the male carries the gene.
