Nov 30, 2023 · A length of DNA that codes for a single polypeptide or protein is called a gene. The position of a gene on a chromosome is its locus (plural: loci) Each gene can exist in two or more different forms called alleles.
Nov 3, 2023 · Inheritance is the transmission of genetic information from generation to generation. Alleles are variations of the same gene. As we have two copies of each chromosome, we have two copies of each gene and therefore two alleles for each gene. One of the alleles is inherited from the mother and the other from the father.

Inheritance. Test yourself. Monohybrid Crosses. When two parents that differ in only one characteristic breed, the process is called a monohybrid cross. Monohybrid crosses allow the genotype of offspring to be predicted. Parental genotype. The first step in constructing a monohybrid cross involves identifying the parental genotypes. E.g.
