Question

16/17 what role does crossing over play in genetic recombination? it ensures genes are inherited together it has no effect on genetic inheritance it prevents genes from mixing it allows genes to swap positions on chromosomes

Explanation:

Crossing over is a process in meiosis where homologous chromosomes exchange genetic material. This exchange allows genes to swap positions on chromosomes, which is a key mechanism in genetic recombination. The other options are incorrect: ensuring genes are inherited together is the opposite of what crossing over does (it promotes mixing), it has a significant effect on genetic inheritance (not no effect), and it does not prevent gene mixing but rather enables it.

Answer:

It allows genes to swap positions on chromosomes
