What is the role of meiosis to sexual reproduction?
Meiosis produces daughter cells with half the genetic material of normal cells. This means that when the gametes from each parent meet, the resulting offspring will once again have the correct number of chromosomes. Meiosis allows half of the chromosomes come from each parent - which is vital for sexual reproduction.
Would a skin cell mutation on your hand affect your offspring?
No. Skin cells are somatic cells. Your offspring come from gametes which are made by germ line cells. Only mutations in germ line cells or your gametes are passed on to your offspring.
What is another name for sex cells?
Another word for sex cells is gametes. A male and female gamete come together to form a zygote: the first cell of the new organism.
Will offspring have more or less chromosomes?
Normally, a mammal offspring will have 46 chromosomes, the same number as each of their parents; half of those chromosomes will come from each parent. However, there are mutations which can cause exceptions to this. For example, offspring with Trisomy 21, more commonly known as Down Syndrome, have an extra 21st chromosome (instead of the usual two--one from each parent). Mutations like this can have effects that range from mild to fatal.
What happens to chromosomes in the nucleus of a body cell when it forms reproductive cells?
Chromosomal number become halved.Diploid cells be come haploid.
What happens to the number of chromosomes in a sex cell?
They're in half. Once the two cells come together the full amount of chromosomes are there.
Why is it important that sex cells have exactly the number of chromosomes as the body cells?
The DO NOT "have exactly the number of chromosomes as the body cells", they have 1/2 that number. This is so that when two sex cells come together to form an embryo, the cells of that embryo have exactly the same number of chromosomes as the body cells of the two parents and not twice that number.
Why must a gamete have only one half the number of chromosomes in body cells?
A gamete will only have one half of the number of chromosomes found in body cells because two gametes have to come together. This means that the two gametes have to have only half of the chromosomes.
Do males start out female?
No. Biological sex is coded in the sex chromosomes of the sperm and egg cells that come together to make a person. From the moment of conception, sex is determined by these chromosomes.
How many chromosomes does a white blood cell have?
It has 46 chromosomes because it is a body cell. All body cells have 46 chromosomes except our sex cells, which have 23. Body cells are refered to as 2n, or diploid, while sex cells are just n, or haploid. When sex cells combine they form another regular body cell, because the chromosomes come together.

Meiosis allows half of the chromosomes come from each parent - which is vital for sexual reproduction.
The similarities of the sperm cells and the egg cells?
Answer:Both have haploid number of chromodomes i.e they contain half no. of chromosomes which is 23 while our other body cells contain 46 chromosomes.
Would a skin cell mutation on your hand affect your offspring?
No. Skin cells are somatic cells. Your offspring come from gametes which are made by germ line cells. Only mutations in germ line cells or your gametes are passed on to your offspring.
How do the numbers of chromosomes in cells compare with the number of chromosomes in sex cells?
The mother gives the egg and the father gives the the sperm and wine they come to get it can make a zygote in other words the baby
Why do human sex cells have only half the number of chromosomes?
Assuming you mean half the number of chromosomes in an average cell, they have half the number because they combine with their opposite (sperm or egg) to create a "complete" cell, which then becomes a living organism.
Why must gamete have only half the number of chromosomes found in a body cell?
A gamete will only have one half of the number of chromosomes found in body cells because two gametes have to come together. This means that the two gametes have to have only half of the chromosomes.
If there are 46 chromosomes in a human body where does half come from?
Half come from your mom's egg and half come from your dad's sperm.
