Here you will learn about the basics of Gregor Mendel's experiments, which defined the basic patterns of inheritance. We will also examine Morgan's early experiments on linkage and the discovery of ...

Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. Often, it is impossible to determine which ...

In Mendelian inheritance patterns, you receive one version of a gene, called an allele, from each parent. These alleles can be dominant or recessive. Non-Mendelian genetics don’t completely follow ...

Abstract: Parallel phenotypic evolution, the independent evolution of the same trait in closely related lineages, is interesting because it tells us about the contribution of natural selection to ...

All of the different plants on Earth—from mango trees to marigolds—have come about thanks to the simple rules of genetic inheritance, which determine how traits are passed on from one generation to ...

AbstractWhen populations experience suboptimal conditions, the mechanisms involved in the regulation of phenotypic variation can be challenged, resulting in increased phenotypic variance. This kind of ...
