Question
Which of the following structures are formed by two homologous chromosomes pair during crossing over?
Base Pair
Chromatid
Tetrad
None of these
Base Pair
Chromatid
Tetrad
None of these
Hint:
A tetrad is formed by two homologous chromosomes pair during crossing over
The correct answer is: Tetrad
- In prophase, I, pairs of homologous chromosomes come together to form tetrads or bivalent chromosomes containing four chromatids.
- Recombination can occur between any two chromatids within this tetrad structure.
