Hello everyone in this question we have been asked that which of the fallen characteristic of a trade would help to determine whether the trade was controlled by a single gene or many genes.
00:16
So a single gene effect is that a typical gene, let's say the height gene, capital b here, is responsible for height only.
00:28
And there are no more gene other than this that will be effective for the height.
00:35
But in the many genes basically there will be many genes that will be involved in the height.
00:44
So there will be additive effect of many genes and which will show their equal effects and due to which a one character will be shown.
00:55
So this is known as a polygenic trait, that is the trait that is influenced by more than one gene.
01:06
So option a says that we can know if there is a normal distribution pattern for the trade.
01:12
So if there is a normal distribution pattern, then we can know only about the single gene and not about the many gene.
01:21
Option b says that the role of environment in the distribution.
01:26
Pattern of the trait...
