The statement "Natural selection occurs when there is nonrandom elimination of genotypes from a population due to differences in viability or reproductive success," is true.
What is genotype?
The term "genotype," which basically refers to an organism's genetic makeup, describes the gene pool as a whole. The term can also be used in a more precise sense to refer to the several alleles, or variations of a gene, that an organism possesses. Being a diploid species, humans have two alleles per genetic locus, one of which was passed down from each parent. Each pair of alleles represents the genotype of a specific gene. For instance, sweet pea plants have two alleles for the bloom color gene.
The uppercase letter F stands for the allele that codes for purple flowers, whereas the lowercase letter f stands for the allele that codes for white flowers. Thus, the genotypes FF, Ff, or ff could be present in a diverse population of sweet pea plants. Each plant's phenotype, in this example the outer look of its blossoms, is influenced by its genotype. When two alleles in a genotype are same, the genotype is said to be homozygous; when the two alleles are different, the genotype is said to be heterozygous. Genotyping is the term for the process of identifying a genotype.
