Question

Is height determined by one gene?

Answer 1

Polygenic inheritance

1. Multiple genes that regulate the development of intermediate heritable traits are controlled by polygenic inheritance.
2. Continuous variation caused by polygenic features causes offspring to differ from their parents.
3. A bell-shaped graph is produced by polygenic inheritance because a greater proportion of people exhibit the intermediate trait than the dominant or recessive traits.
4. Polygenic traits exhibit a wide range of variance in their frequency. Variances, covariance, and average are used to determine polygenic inheritance.
5. There are a lot of potential outcomes for polygenic characteristics.
