Dr. katherine pollard, a biostatistical researcher, recently changed the method that she used to compare human and chimpanzee dna. her research showed that the differences between the two species’ dna are in segments called switches, which turn certain genes on or off. what is the most likely outcome of dr. pollard’s research?
theories that are related to the evolution of humans from apes will change.
the laws of segregation and independent assortment will change.
dr. pollard will change experimental methods and repeat the study.
the hypothesis will be rewritten to match the outcome of the study.

The correct option is A. Theories that are related to the evolution of humans from apes will change.

Explanation:

The research from Dr. Katherine will change the theory of evolution of humans from apes because according to the theory of evolution changes in the genetic sequence of apes caused the formation of humans. But Dr. Katherine Pollard's research says that no deletion or addition of genes took place rather the genome of humans and apes is same with certain switches controlling the genome.
