Question

Why are offspring different from their parents?

a. Identical genetic makeup
b. Random assortment of chromosomes
c. Cloning process
d. Environmental factors only

Answer 1

Offspring are different from their parents due to genetic recombination, crossing over, and random chromosome assortment.

Step-by-step explanation:

Offspring are different from their parents due to three processes: genetic recombination, crossing over, and random chromosome assortment.

• Genetic recombination occurs when chromosomes exchange genetic material during gamete formation, creating new combinations of genes.
• Crossing over is when homologous chromosomes exchange segments of DNA during meiosis, leading to the formation of genetically different gametes.
• Random chromosome assortment occurs during meiosis when homologous chromosomes line up randomly, causing different combinations of maternal and paternal chromosomes in the resulting gametes.
