Question

q 14. a cell undergoing a biological process is shown. which process occurs between step 2 and step 3 and creates more genetic diversity in the resulting cells? chromosomal deletion crossing over genome replication chromosome nondisjunction

Explanation:

• Chromosomal deletion: Removes a segment of a chromosome, reducing genetic diversity by losing genes.
• Crossing over: Occurs during meiosis (Step 2 - Step 3). Homologous chromosomes exchange genetic material, creating new allele combinations.
• Genome replication: Duplicates DNA (Step 1 - Step 2), ensuring each daughter cell gets a full set but doesn’t add diversity.
• Chromosome nondisjunction: Causes abnormal chromosome distribution (e.g., trisomy/monosomy), often harmful, not for diversity.

Answer:

Crossing over
