Awoman who has sickle cell anemia passes this disease on to her offspring. this means that the mutation for sickle cell anemia must occur in the woman’s

Sickle cell anemia is a disease in which the oxygen carrying capacity of the red blood cells is reduced. The RBC change its shape and becomes sickle shapes which reduces its surface area and its carrying capacity also decreases.

Sickle cell anemia is an autosomal recessive pattern, which states that both the copies of gene in the cell have mutation in them.

Both the parents carry one copy of the mutated gene and so not show any signs or symptoms but when the zygote is formed it is affected by this disease.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
