Polygenic inheritance, also known as quantitative inheritance, refers to a single inherited phenotypic trait that is controlled by two or more different genes.

Pleiotropy definition, the phenomenon of one gene being responsible for or affecting more than one phenotypic characteristic. See more.

Additionally, we sought to obtain a better understanding of the inheritance, extent and distribution of pleiotropic effects of several components in maize production. Learn the concepts of Class 12 Biology Principles of Inheritance and Variation with Videos and Stories. Moreover, the alleles of pleiotropic genes are transferred in a similar way as alleles of genes affect the single traits. Although a phenotype has various elements, these elements are expressed as a package and the recessive and dominant versions of the package would be visible in the offspring of two heterozygotes in a 3:1 ratio. D. pleiotropic inheritance. A. 46. For the human sex chromosomes, males have A. two X-chromosomes.

Polygenetic Inheritance This refers to the times where one trait is affected by the expressions of many genes. For example, people vary greatly in traits such as height and nose length because 2020-08-27 · Polygenic inheritance is the phenomenon in which a single phenotypic trait is controlled by multiple genes. It is also known as quantitative inheritance. In simple words, polygenic inheritance occurs the single phenotypic trait is controlled by two or more genes. Pleiotropy - the production by a single gene of two or more apparently unrelated effects.

Moreover, the alleles of pleiotropic genes are transferred in a similar way as alleles of genes affect the single traits. Although a phenotype has various elements, these elements are expressed as a package and the recessive and dominant versions of the package would be visible in the offspring of two heterozygotes in a 3:1 ratio. D. pleiotropic inheritance.

Pleiotropy is the phenomenon of multiple effects of a gene. Such genes are known as pleiotropic genes. Phenylketonuria is a famous example of pleiotropy. Monogenic inheritance deals with the inheritance of qualitative characters like seed colour, seed shape, etc.

In Mendelian inheritance, a single gene is involved in determining a single trait. In pleiotropic inheritance, different traits are controlled by (A) many genes (B) one or two genes (C) single gene (D) mutation . neet; aiims; Share It On Facebook Twitter Email. 1 Answer +1 vote . answered Jun 15, 2019 by Uzma (52.9k points) selected Jun 15, 2019 by 2017-04-28 Genes that affect multiple, apparently unrelated phenotypes, are termed as pleiotropic genes and the phenomenon is termed as pleiotropy.

These expressed traits may or may not be related. Pleitropy was first noticed by geneticist Gregor Mendel, who is known for his famous studies with pea plants.
