With the exception of sex cells (eggs and sperm), there will be the same number of chromosomes in all cells of the body. If fruit fly skin cells have eight chromosomes then wing cells will also have eight chromosomes. These body (somatic) cells undergo mitosis. Fruit fly somatic cells have eight chromosomes.

Questions 153 - 156: The pollen tube contains 12 chromosomes and 3 haploid nuclei, so each nucleus will have 4 chromosomes. If each sperm nucleus has 4 chromosomes, then the egg must also have 4 chromosomes and the diploid number for the plant must be 8.

Almost every cell in our body contains 23 pairs of chromosomes, for a total of 46 chromosomes. Half of the chromosomes come from our mother, and the other half come from our father. The first 22 pairs are called autosomes.

Normally, the head of a sperm cell contains one copy of each chromosome. In men with macrozoospermia, the sperm cell head contains extra chromosomes, usually four copies of each instead of the usual one. This additional genetic material accounts for the larger head size of the sperm cell.

In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.

Sperm cell of grasshopper contains e. The chromosome number for grasshopper sperm cells will be 12. But the actual number of chromosomes in the egg cell will be 12 and that of the sperm cells will be 11 or 12.

A fruit fly, for example, has four pairs of chromosomes, while a rice plant has 12 and a dog, 39. How many chromosomes do humans have? Humans have 23 pairs of chromosomes, for a total of 46 chromosomes.

The number of chromosomes in a sperm cell is 23 and the number of chromosomes in an egg cell is 23. A white blood cell does not undergo meiosis; hence, the number of chromosomes is 46, just like every other human body cells that contain a nucleus.
684485
Normally, meiosis causes each parent to give 23 chromosomes to a pregnancy. When a sperm fertilizes an egg, the union leads to a baby with 46 chromosomes.
74858
A sperm cell contains 23 chromosomes with two possibilities for each chromosome. The possible number of sperm cells based on different chromosome combinations is (2)23 = 8,388,608.
1393171
In humans, special cells called germ cells undergo meiosis and ultimately give rise to sperm or eggs. Germ cells contain a complete set of 46 chromosomes (23 maternal chromosomes and 23 paternal chromosomes).
1204419
Human diploid cells have 46 chromosomes (the somatic number, 2n) and human haploid gametes (egg and sperm) have 23 chromosomes (n).
47331
It has only four pairs of chromosomes – three autosomes, and one pair of sex chromosomes. Males do not show meiotic recombination, facilitating genetic studies.
104167
All the cells of the human body except the gamete cells (sperm and egg) contain 46 (23 pairs) of chromosomes. The nerve cell of human beings are somatic cells and hence contain 46 chromosomes.

4 cells form at the end of meiosis 2 with 23 chromosomes. Oogenesis ultimately gives rise to one ovum with the haploid number of chromosomes. True. A sperm cell is a gamete and is haploid.
193707
Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. In fact, each species of plants and animals has a set number of chromosomes. A fruit fly, for example, has four pairs of chromosomes, while a rice plant has 12 and a dog, 39.

In humans, the male gamete is called sperm, and the female gamete is called an egg. When the gametes join they form a cell called a zygote. Human sperm and eggs contain 23 chromosomes. Human zygotes contain 46 chromosomes.
