Select the correct answer.
a. Statement A, B, and C correct
b. The only Statement B is correct.
c. Statement A and B are correct.
d. The only Statement is correct.

Answer 1

Hint: Embryology is a branch of biology that studies the structure and formation of the gametes, and fertilization of gametes, and the formation and development of the embryo.

Complete answer:
Statement A:
- Casper Edrich Wolff is considered as a father of embryology previously.
- He is the german physiologist and the founder of embryology.
- During studies in the university, he had done a lot of research, and where he revived the theory of epigenesis and supported it, previously it was given by Aristotle.
- His revived theory of epigenesis consists of 3 parts, namely, the development of plants, animals, and theoretical considerations.
So the above-given statement A is wrong

Statement B:
- The Father of modern embryology is Karl Ernst Von Baer.
- He is the first person to observe the mammalian ovum and he also utilized the ultrasound in order to know the chronology of the development of the fetus.
- Von Baer along with one other scientist discovered the germ layers.
- The Discovery of germ layers helped to explain the progressive development of the embryo step by step.
So statement B is correct.

Statement C:
- Biogenetics law, which means ontogeny repeats Phylogeny was proposed by Ernst Haeckel.
- Biogenetics law is also called recapitulation, where it states that the developmental stage of one of the embryos has similar features as the adults of the ancestors.
- Which means Ontogeny recapitulates Phylogeny.

Hence, the correct answer is the only Statement B, which is option (B).

Note: One of a good example to understand the biogenetic law is amphibian larval form, tadpole larva has some features of adult fish, in tadpole larva, gills are there for respiration, which is present in fish also, slowly when larva becoming adults, they develop limbs and gills are replaced by the lungs for respiration.
