Which process describes the exchange of genetic material between homologous chromosomes during meiosis?
Correct Answer: Crossing over
- Step 1: Understand that homologous chromosomes are pairs of chromosomes that have the same genes but may have different versions (alleles).
- Step 2: Recognize that meiosis is a special type of cell division that produces gametes (sperm and eggs).
- Step 3: Learn that during meiosis, homologous chromosomes come together and line up closely in a process called synapsis.
- Step 4: Identify that crossing over occurs when sections of these homologous chromosomes swap places with each other.
- Step 5: Realize that this exchange of genetic material creates new combinations of genes, which increases genetic diversity in the offspring.
