Question

Father of modern embryology is
A. Haeckel
B. Von Baer
C. Wolff
D. Aristotle

Answer 1

Hint: Embryo is the stage of development of gametes after fertilization. This stage occurs after the development of the fetus. The branch of biology that deals with the formation of fetus and embryo and also involves the study of gametes or sex cells after fertilization is called embryology.

Complete Answer:
- Father of embryology is Von Baer. Karl Ernst Von Baer is known for his largest contribution to the field of embryology. The Estonian professor named Karl Ernst Von Baer has studied embryo and different development stages that led to the formation of modern comparative embryology.
- Karl Ernst Von Baer along with Christian Pander proposed the green layer theory of development and Van Baer discovered mammalian arum in 1827. The process of fusion of male and female gametes is called fertilization. The process of fertilization can be classified into two types depending on the site of fertilization as internal fertilization and external fertilization.
- When fertilization takes place inside the body of an organism, it is called internal fertilization. Whereas when fertilization occurs outside the body it is called external fertilization. Two gametes i.e. gamete from male and female sperm and arum are involved in fertilization.
- As a result of fertilization, a mass of cell called zygote is formed and then factors start developing organs called embryos. Embryology involves all these studies related to zygote. Embryology involves all these studies related to zygote, embryo and fetus.

Therefore, from the above explanation the correct option is (B) Von Baer.

Note: Sex of the child can be identified with the help of embryology and this has made a drawback as a girl child is killed in mother’s womb which leads to disturbance in sex ratio.
