A student reads information about the passing of genes from one generation to the next.
What can the student conclude about the number of chromosomes in sex cells (egg and sperm)?
Responses
Answer (1)
Answer:A student studying the passing of genes from one generation to the next would learn about meiosis, the process that produces sex cells (egg and sperm). During meiosis, the number of chromosomes in a cell is halved. In humans, body cells have 46 chromosomes (23 pairs). Meiosis reduces this number by half in sex cells, so each egg or sperm has 23 chromosomes. This ensures that when an egg and sperm combine during fertilization, the resulting offspring has the full set of 46 chromosomes (23 from each parent).The student can conclude that sex cells (egg and sperm) have half the number of chromosomes of a body cell, which is 23 chromosomes in humans.
