Heterozygotes
When three or more contrasting genes control a trait, it is called polygenic inheritance. This type of inheritance involves multiple genes interacting to influence a single trait, resulting in a continuous distribution of phenotypes in a population.
genes and allelsMendel's factors are called dominant and recessive factors and are found in a punnet square.
Genes are the factors that control traits. Genes are segments of DNA that provide instructions for building and maintaining an organism, including determining its physical characteristics. These instructions are passed down from parents to offspring through the process of inheritance.
Alleles
The things Gregor Mendel called factors are now known to be composed of genes and alleles. Gregor Mendel is referred to as the 'father of genetics'. He is famous for formulating his law of inheritance.
For him they were just discrete physical units of inheritance. Johanson coined the term "gene" and people started calling them genes. Today for us these factors are parts of DNA, the base sequences that carry the biological information to determine a trait. Mendel factors are alleles of genes.
These are called sex linked genes since they are on the genes that code for sex.
GENES
Genes
The study of inheritance traits is called genetics. It focuses on how traits are passed from parents to offspring through genes and how variations in genes contribute to different traits and characteristics in individuals.
