Web16. maj 2024. · COLD SPRING HARBOR, NEW YORK— Hundreds of genes influence how tall a person is, but most make an imperceptible difference—perhaps a millimeter, for example. Now, a group studying the genetics of Peruvians, one of the world's shortest populations, has turned up a gene variant that cuts a person's height by more than 2 … WebIdentifying other height genes, and variants with large or small effects, is an active area of genetic research. Because height is determined by multiple gene variants (an …

WebIn the case of plant height, one allele caused the plants to be tall, and the other caused plants to be short. When the tall allele was present, the plant would be tall, even if the plant was heterozygous. In order for the plant to be short, it had to be homozygous for the recessive allele.

WebThe turning on or off to the genes is affected by the presence of other genes, making height one of the most varied heritable phenotypes at about 20% variation, so 80% heritability. ...
