How many chromosomes does a new born baby have?

Answer 1

The same amount that are in a child, a teenager, an adult, or a senior citizen, which is 23 pairs (totaling 46 chromosomes) containing genetic material that makes you who you are. Not all people have 23 pairs though. People born with more or less have serious physical and mental diseases.

Answer 2

I think this is an impossible question to answer. Its equivalent to asking how many many hairs does one has on a person's head. When a sperm fertilizes an egg, they form a single cell called a zygote. This cell then divides into two cells, which then divide into four, and eight, and so on. This process of cell division continues through pregnancy, and, in fact, through the entire life span. At birth, an infant is made up of approximately 2 trillion cells, but this number will grow as the child does into adulthood. (Note: This is an extremely rough approximation. Because the number is so huge, it is presently impossible to count or precisely calculate the number of cells in the average human body. Estimates range from 10 trillion to 100 trillion, and there is no consensus in the scientific community. I arrived at the number 2 trillion by assuming that if a 185 lb man contains 50 trillion cells, then an 8 lb newborn contains 2 trillion cells.)

Answer 3

Same as an adult human-- 46. 23 from one parent and 23 from the other. Unless the baby has Down syndrome. Most people have 23 pairs of chromosomes, for a total of 46. But a baby with Down syndrome has an extra chromosome (47 instead of 46) or one chromosome has an extra part. This extra genetic material causes problems with the way their bodies develop.

Answer 4

Each baby will have 46 chromosomes: 23 from the female parent and 23 from the male parent.

Answer 5

the same number as anyone else... 40039958823

or just 46

Answer 6

All humans regardless of age have 46 chromosomes.

Answer 7

Human babies have two sets of 23 chromosomes in their body (somatic) cells, the same as their parents and other humans.

Answer 8

It gets 48 chromosomes from its parents.
