Q
Q: Which process describes the exchange of genetic material between homologous chromosomes during meiosis?
Solution:
Crossing over is the process where homologous chromosomes exchange genetic material, increasing genetic diversity.
Steps: 5
Show Steps
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.
