A

It is usually done when a woman is between 14 โ€“ 16 weeks pregnant

B

It is used for prenatal sex determination

C

It can be used for detection of Down syndrome

D

It can be used for detection of Cleft palate

Solution

Amniocentesis is a medical procedure used in prenatal diagnosis of chromosomal and genetic abnormalities such as Downโ€™s syndrome. Turnerโ€™s syndrome, etc. It also helps in prenatal sex determination, hence there is a statutory ban on it to prevent female foeticide. It is done when woman is between 14 โ€“ 16 weeks pregnant and it does not help in detection of cleft palate.

A

Inbreeding helps in accumulation of superior genes and elimination of undesirable genes.

B

Inbreeding increases homozygosity.

C

Inbreeding is essential to evolve pure lines in any animal.

D

Inbreeding selects harmful recessive genes that reduce fertility and productivity.

A

A is false but R is true.

B

Both A and R are true and R is the correct explanation of A.

C

Both A and R are true and R is NOT the correct explanation of A.

D

A is true but R is false.

Solution

Amniocentesis is not promoted for sex determination in the Reproductive and Child Health Care Programme due to the risk of female foeticide, making Assertion A false. However, Reason R correctly states that banning amniocentesis helps prevent female foeticide, making it true. Therefore, option (a) is correct.

A

It decreases the productivity of inbred population, after continuous inbreeding.

B

It decreases homozygosity.

C

It exposes harmful recessive genes that are eliminated by selection.

D

Elimination of less desirable genes and accumulation of superior genes takes place due to it.

Solution

Inbreeding increases homozygosity, which can lead to the expression of harmful recessive genes, but it does not decrease productivity in the short term. NCERT XII chapter Reproductive Health discusses the advantages and disadvantages of inbreeding, so option (a) is not an advantage.

A

Both A and R are correct and R is the correct explanation of A

B

Both A and R are correct but R is NOT the correct explanation of A

C

A is correct but R is not correct

D

A is not correct but R is correct

A

Coitus interruptus

B

Periodic abstinence

C

Lactational amenorrhea

D

Vaults

Solution

The correct answer is option (4) as Vault is a barrier method of contraception which is made of rubber that is inserted into the female reproductive tract to cover the cervix during the coitus. โ€ข Option (1) is incorrect as coitus interruptus is a natural method of contraception in which male partner withdraws his penis from the vagina just before ejaculation so as to avoid insemination. โ€ข Option (2) is incorrect as periodic abstinence is also a natural method of contraception in which couples avoid coitus during the fertile period. โ€ข Option (3) is incorrect as lactational amenorrhea is also a natural method of contraception which is based on the fact that ovulation and therefore the cycle do not occur during the period of intense lactational following parturition.

A

High fatality risk to mother

B

Expensive instruments and reagents

C
