How do the number of chromosomes in gametes differ from those in somatic cells?
Gametes are cells involved in reproduction. In humans, these are the spermatozoon and ovum, or sperm and egg. When organisms reproduce, these two types of cells fuse together to form...

How many chromosomes are in a sperm cell from an animal whose somatic cells have 32 chromosomes (2n=32)? If 2n=32, how many chromosomes are in a haploid cell?
So in an animal with 32 (2n) chromosomes in somatic cell, number of chromosomes in sperm will be 16 (n).

Is it true that your somatic cells have chromosomes just like the ones in your dad's sperm and your mom's egg, but that those chromosomes are not so similar to the chromosomes that your dad had in his somatic cells? How can this be explained?
Somatic cells will be in diploid condition and Germ Cells will be in Haploid condition. So, Somatic cells cannot have chromosomes like those in the sperm or egg cell.

Is a kidney cell an example of a sex cell, a germ cell, a somatic cell or a haploid cell?
Kidney is not a reproductive organ, hence there is no germ cell or haploid cell in kidney. Cells in kidney are all diploid.

How many chromosomes would the sex cells of an organism with $12$ chromosomes have?
Is it 12 pairs of chromosomes or just 12 chromosomes. If it is 12 pairs, the sex cells (or gametes) will have half the number of pairs of chromosomes i.e....

A fruit fly has diploid cells with 8 chromosomes. How many chromosomes are in its haploid gametes?
Diploid cells always have an even number of chromosomes because the chromosomes are found in pairs (2n). Haploid cells only contain half the number of chromosomes (n). So you just...

Which of these correctly distinguishes mitosis from meiosis?
A) Mitosis occurs in germ cells and meiosis occurs in somatic cells.
B) Crossing over takes place in mitosis and not in meiotic cell division.
C) Meiosis produces four 2N daughter cells; mitos
Recall that somatic cells are body cells excluding the reproductive cells. For example, this includes cells of the liver, skin, stomach, but not of sperm or the human egg. In...

The platypus has five pairs of sex chromosomes and 21 pairs of autosomes. When a platypus cell undergoes meiosis, how many chromosomes will the daughter cells have?
Platypus is an exceptional mammal to have so many number of sex chromosomes, i.e. 10 in each individual. Sex of the progeny is determined by the sperm as it may...

The body cells of a hamster have 44 chromosomes. How many chromosomes would the gametes of a hamster have?
The sperm of the father, when it fuses with the egg, the embryo has 44 chromosomes. To find the number of chromosomes for each gamete, divide the total number by...

A sperm cell of an alligator has 16 chromosomes.what is the total number of chromosomes normally present in a stomach cell of this alligator?
A)8 B)16 C)32 D)48
Basically, a germ cell (sperm or egg cell) is $n$. Now, the stomach cell, which is a somatic cell, is $2n$. If you substitute $2(16)=32$ Germ cells have gametes while...
