Question
Chapter 14, Problem 2MCQ
Summary Introduction
Introduction:
When a horse and a donkey are mated, the mule is obtained as a product. Thus, mule is a hybrid and develops normally into strong, healthy adult but it is an example of infertile hybrid as mule cannot pass their genetic information down to future generations, so they are genetic dead-end.

Students have asked these similar questions
Options are
a. Hybrid offspring.
b. Speciation
c. Adaptive radiation.
d. Mechanical isolation.
Which could lead to allopatric speciation by two populations of snail?
Group of answer choices
A. creation of a new mountain range between two populations
B. a mutation in all members of one population which prevents gamete fusion between the two populations
C. a change in breeding time of one population
D. a change in mating behavior in one population but not in the other
Give typing answer with explanation and conclusion
Sympatric Speciation occurs when traits change within an interbreeding population due to a cell division error such as polyploids.

You can get a free genome sequence – an analysis of all of your DNA that includes a report of your ancestry, traits and a medical profile. The medical profile tells you about diseases for which you have a low risk of getting, and also those you have a high risk of getting. Are you interested? Why or why not?arrow_forward
