In humans, each parent contributes 23 chromosomes.
In general, each parent of any species contributes the haploid number of chromosomes, which is the number of chromosomes in a single set of chromosomes.

How does the number of chromosomes in gametes of an organism that reproduces sexually differ from the numbers of chromosomes in other cells?
Unlike somatic (body) cells, gametes have two time the number of chromosomes as body cells. Gametes (2n). Body cells (n). For example, human 46 chromosomes in gamete cells but half of that (23) in body cells.
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
During normal mitotic cell division a parent cell having four chromosomes will produce two daughter cells containing how many chromosomes?
There will be 23 chromosomes in each daughter cell. This is half the usual amount. This is referred to as hapliod. Since meiosis only occurs to produce eggs and sperm it makes sense that each egg and sperm should contain only half the "usual" amount. Therefore you literally get half your genes from your mother (egg) and half your genes from your father (sperm). Once fused as a zygote (the cell from which the baby will be formed) now has the correct or "usual" number of chromosomes - 46 or 23 pairs.
What is a baby's gender if he or she has XXY sex chromosomes?
Male - in humans the sex is determined by the presence of a Y chromosome. In other animals sex can be determined by the ratio of sex chromosomes, or the total number of chromosomes.
Cells that contain half the usual number of chromosomes are?
A sperm cell and an egg cell. They combine to make a baby with full chromosomes.
What types of chromosomes does each parent pass on to a child?
Each parent gives a baby 23 pairs or 46 chromosomes to the offspring
Can an offspring look like just one parent?
because of the chromosomes the parents will give 23 of their chromosomes to the baby born and then that baby has 46 chromosomes in all.this method is called mitosis.
What causes a baby to come out deformed?
Mutations in their chromosomal DNA. Each parent gives chromosomes to the baby, and when they meet sometimes there are doubles of chromosomes, missing chromosomes, or mutated chromosomes which cause abnormalities in the DNA and overall the child.
What is the number 23 usually referring to?
The number 23 usually refers to the fact that each parent contributes 23 numbers to a child's chromosomes. The 23rd chromosome determines the sex of the baby.
How much genetic information is passed from parent to offspring?
i think you meant "...from each parent?" Here it goes. All humans have 23 pairs of chromosomes, or 46 in total. When mommy and daddy want to have a baby, they do the deed, and each provides 23 chromosomes, one from each pair, to the zygote forming in the mother. This is to keep the number of chromosome at a constant number. Now the baby will be born with 23 pairs of chromosomes, it 46 in total. Edited answer: 50% from each parent
How does the number of chromosomes in gametes of an organism that reproduces sexually differ from the numbers of chromosomes in other cells?
Unlike somatic (body) cells, gametes have two time the number of chromosomes as body cells. Gametes (2n). Body cells (n). For example, human 46 chromosomes in gamete cells but half of that (23) in body cells.
Which parent determimes the baby's blood type?
The alleles for Immunoglobulins are carried on autosomal chromosomes, not on sex chromosomes. Hence, both parents are equally responsible for a baby's blood type.
What parent carries male baby chromosomes?
The father carries the Y chromosome which codes for male reproductive organs.
How many chromosomes do the parents have?
A mother have 46 chromosomes and a father have 46 chromosomes when they come together in fertilization these chromosomes splits 23 from the mother (egg) and 23 from the father (sperms) and so forming the new zygote which is the baby with 46 chromosomes
What are the main difference mitosis and meiosis?
Mitosis results in two new daughter cells being formed from one parent cell. The daughter cells are identical in both size and genetic make up to the original parent. The daughter cells have the full compliment of chromosomes (46 in humans). This is called the diploid number (n). Mitosis occurs in all somatic cells and is used for growth and cell replacement. Meiosis is the production of four new daughter cells from one parent cells. Meiosis only occurs in gametes (sperm and ova). This process results in the production of four completely different cells. Each new cell has half the compliment of chromosomes this is called the haploid number (2n). In humans the haploid number is 23 chromosomes so when the sperm and egg fuse, the egg has 23 chromosomes and the sperm has 23 chromosomes so the baby (zygote) has half the number of chromosomes from its mother and the other half from its father.
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
What is true about a baby with two X chromosomes?
A baby with two X chromosomes is female.
