Hi,

The given scenario is sa hypothetical scenario. Practically it may not happen. During gamete formation, there is a crossing over stage during which reshuffling of genes takes places. After this stage, a chromosome will have some genes from one parent and some from another parent.

With continuous research and studies, majority of common human traits have been proven as dominant or recessive. Hence, if we consider the above case, irrespective of the situation mentioned about the transfer of genes from a parent to a child, dominant and recessive traits are known. For example, Curly hair is a dominant trait while straight hair is recessive.
