Which of the following is true about crossing over?
A) It results in a new cell called a zygote.
B) It creates new hereditary combinations.
C) It increases the probability that nontwin siblings will be genetically identical.
D) It decreases the chances that some members of a species will survive ever-changing environments.

Question

Quizplus · Accepted Answer

Crossing over, which occurs during meiosis, involves the exchange of genetic material between homologous chromosomes. This results in the creation of new hereditary combinations. It does not result in a new cell called a zygote nor does it increase the probability that nontwin siblings will be genetically identical. It may or may not decrease the chances that some members of a species will survive ever-changing environments, depending on the specific genetic variations that are produced.
