22. Sickle cell disease is... (1 point) A)autosomal dominant

B)dominant

C)sex-linked recessive

D) autosomal recessive

D. autosomal recessive

Explanation:

Sickle cell is a hereditary disease caused by a mutation in one of the genes that encode the protein hemoglobin. It is inherited in an autosomal recessive pattern, meaning that both copies of the gene have mutations. The mutation causes the red blood cells to have a sickle shape.

Hope this helps.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
