Question

Consider statements about animal husbandry: 1. Artificial insemination improves cattle breeds. 2. Multiple Ovulation Embryo Transfer is used in poultry. 3. Crossbreeding combines traits of two breeds. Which are correct?

A. 1, 2 and 3

B. 1 and 2 only

C. 1 and 3 only

D. 2 and 3 only

Answer: Option C

Solution (By JKSSB Mock Tests)

Artificial insemination allows the use of superior bull semen to improve cattle genetics widely. Multiple Ovulation Embryo Transfer (MOET) is a technique used in cattle and other mammals to increase herd improvement rates, not in poultry (which uses hatching eggs). Crossbreeding involves mating animals of different breeds to combine desirable traits and exploit hybrid vigor. Thus, statements 1 and 3 are correct.

B. Polygenic inheritance

C. Epistasis

D. Incomplete dominance

Correct Answer: Option A

Explanation:
Pleiotropy occurs when a single gene affects two or more distinct phenotypic traits. This happens because the gene product (protein) may be used in multiple biological pathways or expressed in different tissues. Examples include phenylketonuria (PKU), sickle cell anemia, and Marfan syndrome. Epistasis involves the interaction of different genes, polygenic inheritance involves multiple genes affecting one trait, and incomplete dominance is a single gene interaction.

A. Ribosome

B. Golgi apparatus

C. Mitochondria

D. Nucleus

Correct Answer: Option A

Explanation:
Translation is the process where the genetic code carried by mRNA is decoded to synthesize a specific sequence of amino acids, forming a protein. This process occurs at the ribosomes in the cytoplasm. Ribosomes read the mRNA codons and match them with the anticodons of tRNA molecules carrying the corresponding amino acids.

Correct Answer: Option C

Explanation:
Chromosomes consist of DNA wrapped around histone proteins. Somatic cells have 46 chromosomes (23 pairs), gametes 23. A karyotype is a picture of chromosomes, not sequence.
