Introduction:
Reptile eggs are called as the amniotic egg after fertilization. It consists of four layers called as allantois, amnion, chorion and yolk-sac. The embryo develops inside the fertilized egg in a watery environment.

Answer to Problem 1MC
Correct answer:
In a reptile egg, the extra embryonic membrane that encloses the embryo in a watery environment is the amnion.
Therefore, option (b) is correct.
Option (b) is given as “amnion”.
Explanation of Solution
Justify reasons for the correct statement:
Amnion layer encloses the fertilized embryo in a watery environment containing the amniotic fluid. It gives protection during the stages of development of the egg. It forms the ectoderm, mesoderm and endoderm during the fertilization of the egg.
Hence, option (b) is correct.
Justify reasons for the incorrect statements:
Option (a) is given as “allantois”.
Allantois forms separate sac which secretes the
Option (c) is given as “chorion”.
It is present near the egg shell and helps in the exchange of gases like oxygen and carbon-dioxide. Hence, it is a wrong answer.
Option (d) is given as “yolk-sac”.
It contains the egg yolk. Hence, it is a wrong answer.
Hence, options (a), (c), and (d) are incorrect.
Reptile amniotic eggs contain amnion layer with watery environment which prevents the egg under shock and stress.

Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a cancerous form. i The recessive form is a normal protein - in other words, no neurofibromatosis.moovi A typical pedigree for a family that carries neurofibromatosis is shown below. Note that carriers are not indicated with half-colored shapes in this chart. Use the letter "N" to indicate the dominant neurofibromatosis allele, and the letter "n" for the normal allele.
