How many chromosomes do germ cells have
Web2. If a sperm containing 46 chromosomes fused with an egg containing 46 chromosomes, how many chromosomes would the resulting fertilized egg contain? Do you think this would create any problems in the developing embryo? 46 + 46 = 92; a developing embryo would not survive if it contained 92 chromosomes. WebThe difference here is that each of the resulting gametes has only half of the chromosomes of the original cell, and thus only half of the genetic information for life. I hope this helped!

Homologous chromosomes (Figure 7.5. 2 ), or homologs, are similar in size, shape, and genetic content; they contain the same genes, though they may have different alleles of those genes.
After migration primordial germ cells will become oogonia in the forming gonad (ovary). The oogonia proliferate extensively by mitotic divisions, up to 5-7 million cells in humans. But then many of these oogonia die and about 50,000 remain. These cells differentiate into primary oocytes. In week 11-12 post coitus the first meiotic division begins (before birth for most mammals) and remains arrested in prophase I from a few days to many years depending on the …
