23, Humans in any form have 23 pairs of chromosomes or 46 total chromosomes. What may be confusing you is that half of each pair or 23 chromosomes, is provided by each parent.

What else can I help you with?
Houseflies have six pairs of chromosomes if two houseflies are crossed how many possible types of fertilized eggs could result from the random lining up of the pairs?
Houseflies have six pairs of chromosomes, so when two houseflies are crossed, there are 2^6 possible combinations of fertilized eggs that can result from the random lining up of the pairs. This gives a total of 64 possible types of fertilized eggs that could result from the cross.
How many chromosomes do humans have per cells?
Depends on the cell. 46 is probably the number you're looking for. 23 pairs. Mature red blood cells have none. Gametes, eggs and sperm have 23, not 23 pairs.
What is a cell with pairs of chromosomes called?
Somatic (diploid) cells have pairs of chromosomes. They have 46 chromosomes, making 23 pairs.Gametes are sex cells (eggs and sperm), they only have 23 chromosomes total. This is because they will combine with another gamete to form an embryo that will have 46.
Number of chromosomes in a human body?
Each cell has 46 chromosomes. Eggs and sperm each have 23, thus a human has 46.
How can there be indentical twins in triplets?
If a woman has two eggs that are fertilized and one of those eggs split, you will get one unique set of chromosomes and a pair of identical chromosomes.
How many pairs of chromosomes does a human have in all their body cells?
There are 23 pairs or 46 individual chromosomes in a humans cells. 22 pairs of autosomes and 1 pair of sex chromosomes in normal humans. (There are disorders such as Turners syndrome and Klinefelter syndrome that result in different numbers of chromosomes.)
Where are homologous pairs of chromosomes not normally found in?
Homologous pairs of chromosomes are not normally found in gametes, which are reproductive cells such as eggs and sperm. This is because gametes are haploid, meaning they only contain one set of chromosomes, while homologous pairs consist of two sets of matching chromosomes.
What is the number of chromosomes in a somatic cell?
Somatic cells (of the body) are diploid (having 46 chromosomes). Only gametes (eggs and sperm) are haploid (having 23 chromosomes). So that during fertilization the egg and sperm combine their chromosomes resulting in a new life with 46 unique chromosomes (in humans, of course. Others species has differing numbers of chromosomes). The haploid combination ensures genetic diversity.
How many pairs of chromosomes are found in a Split Pea cell?
Normal egg cells are haploid and a haploid cell can`t have pair of chromosomes.Pair of chromosomes actually means homologous pairs of chromosomes which are not present in eggs. Human egg contains 23 unpaired chromosomes and Drosophila egg contain 4 unpaired chromosomes which can`t be called 2 pairs as they are not homologous. Some abnormal eggs eg of parthenogenetic animals may possess paired chromosomes.
How many chromosomes are in a sperm cell and in an egg cell?
Each gamete (or egg/sperm cell) has 23 chromosomes. So both egg & sperm cells have 23 chromosomes, however because gametes undergo meiosis the chromosomes are haploids so they don't look like X's. So they are not actually in pairs, as just eggs & sperm. They pair up once an egg is fertilized.
Chromosome pairs what and are distributed to sex cells?
Chromosome pairs undergo a process called meiosis during which they are divided. One of the pairs, known as the sex chromosomes, determines the sex of an individual. In humans, females have two X chromosomes, while males have one X and one Y chromosome. These sex chromosomes are distributed randomly to sex cells during meiosis, resulting in the formation of eggs (in females) and sperm (in males) with varying combinations of sex chromosomes.
Is ovaries haploid or diploid?
diploid
