Does each gene cause a single trait or does each gene cause multiple traits?
Dear Student,
Please find below the solution/link to the asked query:
Each gene can cause both i.e. single trait as well as multiple traits.
There are many traits that are controlled by the single gene. Some of which are as follows:

There are many traits that are controlled by the single gene. Some of which are as follows:
- Presence of Freckles: Freckles are produced as a result of variation of MC1R gene while other genes are involved in influencing the trait.
- Red/green color blindedness is controlled by a single gene.
- PTC tasting or Phenylthiocarbamide receptors is controlled by a single gene, the tasters usually carry one copy of the tasting version of the gene.
- Similarly there are traits such as Huntington disease, Phenylketonuria , Hemophilia A that involves only one gene.
An example of a human polygenic trait is adult height.
