Question

Consider the following statements (A D) and select the correct option stating ones are true (T) and false (F)?
A. Genes located on different chromosomes always show linkage.
B. Homologous non-sister chromatids participate in crossing over during gamete formation.
C. The frequency of crossing over between any two genes is generally proportional to the distance between them on the chromosome
D. Two non-sister chromatids participating in crossing over at any given point will lead to the formation of one type of gamete.

• A. A - T, B - F, C - F, D - T
• B. A - F, B - T, C - F, D - T
• C. A - F, B - T, C - T, D - F
• D. A - T, B - F, C - T, D - F

Answer 1

The correct option is A A - T, B - F, C - F, D - T

A is false as linked genes are present on same chromosome.

B - True.

C- True

D- False - as non sister chromatids are involved in crossing over , gametes formed are of different type.

So, the correct option is A-F, B-T, C-T, D-F'.
