In the context of genes and the environment, an organism's genotype can change over the course of its lifespan. a. true b. false

b. False

Explanation:

We define as genotype the genetic constitution of an organism, that is, the set of genes that an individual has. This genetic constitution comes from the ancestors that this being has and is unchanging, that is, it does not change over the life of the individual.

In humans, the genotype is formed by a combination of the father and mother genes. Imagine, for example, that a woman has normal skin pigmentation but has a gene for albinism, so she is Aa. When we refer to the genes she has, we mean her genotype.
