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.

Sister chromatids are of the same chromosomes, while the non-sister chromatids are of the different chromosomes. Thank you.

When DNA has replicated, the copied sister chromatids remain attached to what structure?
Each chromatid contains one linear DNA molecule. Actually replication remains incomplete at centromeric region till separation of chromatids during anaphase.

What is the chromosome number of a somatic cell having two of each type of chromosome typical of the species?
The somatic cells have diploid number of chromosomes, one half from maternal and other half from paternal side. The pair of chromomsomes are known as homologous pairs, Where...

Which kind of cell can divide by mitosis, a germ cell or a somatic cell? What kind can undergo meiosis?
Mitosis is for growth and repair. One cell becomes two daughter cells with each containing 46 chromosomes and retains the exact feature of that cell. Meiosis is for reproductive cells....

If nondisjunction occurs in humans for sister chromatids of one chromosome during Meiosis II, will any normal gametes result? What chromosome number would each gamete have?
This results in monosomy or trisomy where the cell has an extra or missing chromosome which leads to a variety of genetic disorders. Also, if a cell is missing one...

If you have non sister chromatids bearing alleles Aa, when will they separate?
occurs in 2stages, i.e. meiosis-I and meiosis-II. Pairing of homologous chromosomes bearing alleles AA and aa occurs. Crossing over occurs during metaphase-I and two homologous chromosomes bearing alleles...

Are all unicellular organisms haploid? If not, how do we know a cell is haploid or diploid?
All chromosomes are different in appearance as far as the length and position of centromere is concerned in haploid cells . Haploid number means a set of chromosomes which are...
