Genotype

The genetic makeup of an organism, representing the alleles inherited from both parents, which determines specific traits.

Phenotype

The observable physical and physiological traits of an organism, resulting from the interaction of its genotype with the environment.

Meiosis

A type of cell division that reduces the number of chromosomes by half, resulting in four genetically diverse gametes. It is essential for sexual reproduction.

Fertilization

The process by which male and female gametes combine to form a zygote, restoring the diploid chromosome number and initiating the development of a new organism.

Chromosome

A thread-like structure in the nucleus of cells, made of DNA tightly coiled around proteins that carries an organism’s genetic information from one generation to the next, organizing it for cell division and growth.
