The sites where homologous chromosomes remain connected after separating during diplotene are referred to as chiasmata. The pairing of homologous chromosomes is termed synapsis. The process in which DNA from one cell type, when introduced into another, transfers some traits of the former to the latter is called transformation.

1. (a) True
2. (b) False
3. (c) Partially true
4. (d) None of the above

Correct answer: (a) True

Solution

Each statement uses the correct term: chiasmata are the visible points where homologous chromosomes remain attached after crossing over, synapsis is the pairing of homologous chromosomes, and transformation is the transfer of traits via uptake of foreign DNA. Since all three definitions are accurate, the statement is true.
