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. 2 and 3 only

B. 1 and 2 only

C. 1 and 3 only

D. 1, 2 and 3

Answer: Option C

Solution (By JKExamLibrary)

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.

Correct Answer: Option A

Explanation:
Glyoxysomes are specialized peroxisomes found in germinating oil seeds. They contain enzymes of the glyoxylate cycle, converting fatty acids to carbohydrates until the seedling can photosynthesize.
