A pleiotropic gene:
Is a gene that evolved during the Pliocene era.
Is expressed only in primitive plants and animals.
Control multiple traits in an individual.
Controls a trait only in combination with another gene.
Is a gene that evolved during the Pliocene era.
Is expressed only in primitive plants and animals.
Control multiple traits in an individual.
Controls a trait only in combination with another gene.
Hint:
Control multiple traits in an individual
The correct answer is: Control multiple traits in an individual.
In genetics, Pleiotropy is defined as the expression of multiple traits by a single gene.
A pleiotropic gene is a single gene that controls more than one trait.
For example: A human genetic disorder called Marfan syndrome is caused by a mutation in one gene, yet it affects many aspects of growth and development, including height, vision, and heart function. This is an example of pleiotropy, or one gene affecting multiple characteristics.
