Detailed explanation-2: -Through the process of fertilization, egg and sperm join to make a cell with 46 chromosomes (23 pairs), called a zygote. For each chromosome pair, one homologous chromosome came from each parent. They have the same genes arranged in the same order, but there are small variations in the DNA letters of those genes.
Detailed explanation-3: -There are 46 chromosomes in primary oocytes. Primary oocytes undergo meiosis in a process called oogenesis to produce secondary oocytes that contain 23 chromosomes.
