What changes in chromosome number occurs during fertilization? When a sperm fertilizes an egg, the union leads to a baby with 46 chromosomes. But if meiosis doesn’t happen normally, a baby may have an extra chromosome (trisomy), or have a missing chromosome (monosomy).
What change in chromosome number happens during fertilization? It is a two-step process that reduces the chromosome number by half—from 46 to 23—to form sperm and egg cells. When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have the usual 46.
Does fertilization reduce chromosome number? Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes!
What happens to chromosomes and genes during fertilization? When the genetic information from the parents combines together during fertilization, a genetic blueprint is created in the nucleus of the fertilized egg that is the “DNA blueprint”. The fertilized egg duplicates and divides into two identical cells and a copy of the “DNA blueprint” is reproduced in each cell.
