Q

Darwin borrows from Malthus: THEORY OF EVO

A

Individuals having variation that is advantageous for survival to reproductive age produce more offspring (and more offspring that survive) than individuals lacking this variation.

116
Q

A

An outdated, dis-reputed theory that the phenotype of an offspring was a uniform blend of the parents’ phenotypes.

118
Q

Define: Mutation

A

A random change in a gene or chromosome, creating a new trait that may be advantageous, deleterious, or neutral in its effects on the organism.

119
Q

Define: Gene Flow
