Recessive means a weaker trait in genetics. Genes that mask other genes are called dominant and genes that can be masked are the weaker or recessive genes. Cystic fibrosis is a hereditary disease that mainly affects Caucasian children of European decent. The disease is caused by a defect in which cells make chloride pumps but fail to install them in the plasma membrane. Both parents must carry the recessive gene for a child to inherit the condition.

Cystic fibrosis can be carried in a heterozygote and kill a homozygous offspring.

mr Goodwill [35]

a specialized form of cell division occurs to form egg and sperm cells : Mitosis, Meiosis, Fertilization

What is Fertilization?

During fertilization, the main nucleus of an embryo is formed by the combination of a paternal sperm nucleus and a maternal egg nucleus. In reality, the process of fertilization in all organisms involves the union of the genetic material from two gametes, or separate sex cells, each of which has half the number of chromosomes that are typical for the species. In microorganisms and protozoans, the earliest type of fertilization involves the transfer of genetic material between two cells.

The fusing of the two gametes' membranes, which results in the creation of a channel that allows material to go from one cell to the other, is the first critical event in fertilization.
