D. It performs all functions for the organism.
This is the correct answer! Hope that helps!
Answer:
50%
Explanation:
Both parent's genotype is Bb because they are hairless and alive.
If it has a homozygous dominant genotype (BB), the dog will die in utero.
If it has a heterozygous genotype (Bb), the dog will be hairless but won't die.
If it has a homozygous dominant genotype (bb), the dog will have hair.
The ratio of BB:Bb:bb is 1:2:1 meaning that there is a 50% probability of having a live hairless puppy.

The pattern of embryonic development in which only the cells lacking yolk subsequently undergo cleavage is called meroblastic development, which is typical of birds.
Therefore, the correct answer is Option D.
<h3>What is embryonic cleavage?</h3>
- Embryonic cleavage is the division of cells which occurs just after fertilization and are involved in the early development of the embryo.
- The different cells formed after cleavage are called the blastomeres and these are present in a compact mass called the morula.
- The end product of cleavage is blastula which is a hollow sphere with a cavity called blastocoel.
- Cleavage can be of different types depending upon the concentration of yolk in the egg as yolk does not undergo cell division.
- In holoblastic cleavage, the entire egg divides as yolk is present in very less concentration.
- In meroblastic cleavage, only the cells lacking yolk divide.
