Detailed explanation-1: -All 46 chromosomes. No, sex cells have a half set of chromosomes. 23, one from each pair. That is correct.
Detailed explanation-2: -Egg and sperm cells have just 23 chromosomes each. That’s half as many chromosomes as regular cells. Through the process of fertilization, egg and sperm join to make a cell with 46 chromosomes (23 pairs), called a zygote.
Detailed explanation-3: -How many chromosomes do humans have? Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. In fact, each species of plants and animals has a set number of chromosomes. A fruit fly, for example, has four pairs of chromosomes, while a rice plant has 12 and a dog, 39.
Detailed explanation-4: -46 is generally considered Because each human originates from a single cell. All other cells are just copies of that single cell. And that single original cell, the fertilized egg, the zygote, has 46 chromosomes.
Detailed explanation-5: -The structure and size of the chromosomes are different from each other. Comparing the chromosomes of human females and males based on the size and structure, it can be said that females have 23 different chromosomes and males have 24 different chromosomes. During spermatogenesis, the sperm will have either X or Y.
