Conditional Lethal Genes • an organism lives normally … WebThey may be maintained by gene flow The gene may be common, and not deleterious, in a nearby habitat. If migration from the nearby population is frequent, we may observe the deleterious gene in the population of interest.

Can lethal genes be maintained in a gene pool? - Study.com

Lethal alleles (also referred to as lethal or lethals) are alleles that cause the death of the organism that carries them. They are usually a result of mutations in genes that are essential for growth or development. Lethal alleles may be recessive, dominant, or conditional depending on the gene or genes involved. Lethal … See more Lethal alleles were first discovered by Lucien Cuénot in 1905 while studying the inheritance of coat colour in mice. The agouti gene in mice is largely responsible for determining coat colour.
