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.

Genetic variability is beneficial for a species because it enhances that species’ ability to adapt to changing conditions. Why,
Nuetrik [128]

Answer:  Genetic variability  is beneficial for the survival and adaptation. But a flaw in DNA Replication Control or check may leads to the death of cell or may contribute in the disease or cancer.

Explanation:

Almost every species comes with the diversified collection of genes (genome). And some of the diversity comes from the spontaneous mutation but it occurs on a very low frequency. The genes either express constitutively or occasionally for an important task like genes responsible in the generation of ATP by glycolysis, tricarboxylic acid cycle, electron transport chain etc. While some of the genes are inducible that is only activated in a response to an external stimuli. Genetic variations in inducible genes might account for the adaptability or negligible change in a species genetic expression but genetic variation in constitutive or house keeping genes leads to cancer cell formation or even cell death. like mutation occur in p53 genes dysregulate the cell cycle or mutation occur in DNA polymerase enzyme that is responsible for the incorporation of NTPs (nucleotide tri-phosphates) according to wobble base pairing rule in order to make a complementary new strand from the old or parent strand, will eventually leads to cause mutations ultimately results in cell death or cancerous cell formation.

Mendel observed phenotypic traits during the cross of pea plants. Subsequently, he noted each trait had only two forms.

<h3>Mendel's Experiments</h3>

Mendel crossed pure-breeding pea plants, and then he crossed hybrid generations, as well crossed the hybrid progeny back to parental lines.

From these crosses, Mendel observed the descendence and then formulated a series of inheritance principles.

Mendel noted traits can be divided into dominant and recessive phenotypic characteristics.

Dominant characteristics were inherited in an unaltered manner after hybridization of true breeding [plants.
