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.

Answer:
The Hardy-Weinberg law states that in a sufficiently large population, in which matings occur randomly and that is not subject to mutation, selection or migration, gene and genotypic free frequencies are kept constant from one generation to another, once a state of equilibrium has been reached, which in autosomal loci is reached after one generation.
It is said that a population is in equilibrium when the alleles of the polymorphic systems maintain their frequency in the population throughout the generations.
A group of cells that performs a similar function is known as tissue.
