How many chromosomes are in cells formed during mitosis?
A cell undergoing mitosis has twice the usual number of chromosomes for that species. For example, human body cells have 46 chromosomes, but after DNA replication, which must occur before mitosis, a human body cell will have 92 chromosomes.
Why are eggs and sperm are haploid?
Gametes are sex cells such as sperm and egg so they MUST be haploid because when they combine to make a baby the baby has one full set of chromosomes. not 2.
How many pairs of homologous chromosomes are found in human body cells?
Human cells have 23 homologous pairs. They also must go through meiosis before that. Females have 2 X chromosomes, while Males have an X and a Y chromosome. That's why the males cells decide the gender of the child.
How many chromosomes are present at the end of telophase I?
You must first understand that the cells of different organisms contain different amounts of chromosomes. Humans contain 46. However, during interphase, a cell grows, prepares for mitosis, and doubles its chromosomes. That means 92 chromosomes are present at the end of mitosis. They are still attached (there are 46 pairs of chromosomes that do not split until anaphase).
Why is it important that cells have half the number of chromosomes as body cells?
In sexual reproduction, each parent contributes a sex cell with half as many chromosomes as the normal cells. The two sex cells combine and the zygote will have the proper total of chromosomes. In this way, the offspring inherit genetic information from both parents.
If a human baby's cell contain two chromosomes the baby must be?
A girl
For a human baby to be born a boy he must receive?
must have both a x chromosome and a y
Gametes must be haploid because?
Gametes are sex cells such as sperm and egg so they MUST be haploid because when they combine to make a baby the baby has one full set of chromosomes. not 2.
Why is it important for egg cells to only have 18 chromosomes?
Only in that way do you get a human zygote - each chromosome MUST be paired and there must be 46 total to get a true human. (Note that in reality there are occasional mismatches - either too many or too few - and the result is always a defective child.)
Does XY combination of chromosomes give a female baby?
No, XY combination of chromosomes produces a male baby. To produce a female baby, the combination of chromosomes must be XX. The mother's egg is always X, so the deciding vote goes to the father's sperm to choose an X or a Y chromosome - to see whether we'll be a boy, or a girl.
Why is it important to have half as many chromosomes as normal body cells?
The gametes must have half as many chromosomes as normal body cells because they unite to form a zygote, which is the first body cell of the new organism. For example, human body cells have 46 chromosomes and human gametes (sperm and egg cells) have 23 chromosomes. When the sperm fertilizes the egg, the zygote will have 46 chromosomes, and is the first body cell of the new human.
Is a human baby born in a egg?
No. All fetuses start off as a cell which is called an egg. But human babies are not inside an egg like baby chickens are when chicks are born. Human babies do not need a shell, because the mommy's belly gives the fetus protection for the entire time. Chicks must grow inside the egg shell but outside of their mommy's belly.
What must happen before meiosis can begin?
DNA replicates and forms tetrad—APEX.
Why are there no chicks in eggs when you buy them and eat?
The simple answer is: because they are not fertilized. In order for a baby chick to grow inside an egg and eventually hatch, it must first be fertilized, like a human woman pregnant with a baby that eventually is born. If an egg remains unfertilized, it can be used for human consumption.
Why must gametes be haploids?
It must join with the other gamete to form a diploid number of chromosomes. If it had a diploid number to begin with, the result would be twice the normal amount of chromosomes. A normal cell had "2n" number of chromosomes, and each gametes have "n". If they had "2n" to begin with, the resulting zygote would have "4n", which is clearly not normal in human genome.
what is a baby shower must have?
Must haves for Baby showers include baby bats,diapers,strollers,toys,clothing,cribs and other new born necessities.
