Incorrect: 2/3rds of zygotes spontaneously miscarry.Every human has a starting point. All humans started out as zygotes and every human zygote (left alone) has developed a beating heart.
Right. So? The fact remains that neither zygotes nor gametes have a beating heart.It's part of the process and experience of humanhood. The heart generally develops about 18 days after conception.
Because they have a different number of chromosomes. Why is that important?A human zygote has 46 chromosomes. All normal humans have 46 chromosomes. A gamete (unfertilized egg or a sperm) only has 23 chromosomes each. Therefore, to compare a gamete to a zygote is like comparing apples to oranges. Two different things.
