Adult height in people is at least partially hereditary; tall parents tend to have tall children. But people come in a range of sizes, not just tall or short. What extension of Mendel's model could produce this variation in height

Polygenic Inheritance

Explanation:

Height appears to result from the polygenic inheritance, similar to human skin shading Tallness is a polygenic attribute, constrained by in any event three qualities with six alleles. In the event that you are prevailing for the entirety of the alleles for height, at that point you will be exceptionally tall. There is likewise a wide scope of skin shading across individuals. Skin shading is likewise a polygenic quality, as are hair and eye shading Polygenic inheritance frequently brings about a ringer molded bend when you investigate the population. That implies that a great many people fall in the phenotypic range, for example, normal height, while not very many individuals are at the boundaries, for example, tall or exceptionally short. Toward one side of the bend will be people who are passive for all the alleles (for instance, aabbcc); at the opposite end will be people who are prevailing for all the alleles (for instance, AABBCC). Through the center of the bend will be people who have a mix of predominant and passive alleles (for instance, AaBbCc or AaBBcc)

It may have some of the same features that it’s mother does but, it may have some of the same features that it’s father has as well.
