Why is it significant that the four newly formed cells differ in chromosome content?

By reducing the chromosomes number from diploid to haploid, the chromosomes and genes are randomly rearranged and sorted to produce new gene combinations in the offspring resulting from sexual reproduction

Organelle formed from chromatin as a cell divides?
Chromosome
What is an endospore?
it's a small asexual spore that is formed by some bacteria and contains a copy of chromosome.
One gamete is formed during what process?
The cellular chromosome number is reduced from 2N to 1N.
How many chromosome are in a male and female?
In the case of man the meiosis is otherwise known as spermatogenesis, as a result of which 4 haploid sperms are formed. The sperms differ from the other somatic cells not only in the no. of chromosomes but cytoplasm is also very much reduced. they have acrosomes, tail etc. After reduction division modification of the sperm cells occur which is otherwise known as spermiogenesis. In male the spermatogenesis occur after puberty but then onwards continuous.In the case of females it is known as oogenesis, as result they will be giving rise to only one ovary.(during the first and second meiotic division cell division is anisogamy and give unequal daughter cells in which the smaller ones released as polar bodies.) The ovary is rich in cytoplasm and have haploid no of chromosomes. In the case of human the first meiotic division of all possible primary oocyte takes place in the embryonic stage and second stage occur after puberty periodically one in a month
What can one half of a duplicated chromosome be referred as?
A chromatid is one-half of two identical copies of a replicated chromosome. During cell division, the identical copies are joined together at the region of the chromosome called the centromere.Joined chromatids are known as sister chromatids. Once the joined sister chromatids separate from one another in anaphase of mitosis, each is known as a daughter chromosome.Chromatids are formed from chromatin fibers.Bailey, Regina. "Chromatid." ThoughtCo, Apr. 17, 2017.
How many chromosome in a originalcell compare to those in new cells formed by mitosis?
46 chromosome
How many DNAmolecules make up each original chromosome?
A chromosome is formed from a single DNA molecule.
Organelle formed from chromatin as a cell divides?
Chromosome
Eukaryotic Chromosome are formed primarily of what two molecules?
Eukaryotic chromosomes are formed primarily of chromatids and telomeres
What is bead like structure formed by DNA and his-tone molecules?
Chromosome.
What an endospore?

How could a zygote be produced with an XYY karyotype?
An XYY zygote can be formed if a pair of sex chromosomes fails to separate during meiosis, so the gamete formed has both the X and Y chromosomes. This gamete would then meet the other gamete from the other cell that would contain a Y sex chromosome. The resulting zygote that is formed would have XYY sex chromosomes. This abnormalty where there is an extra chromosome or is missing a chromosome is called nondisjunction.
Is chromosome Y an acrocentric chromosome?
A chromosome is determined to be metacentric, acrocentric or telocentric by the location of its centromere. Centromeres are the point of attachment of two sister chromatids. Sister chromatids are formed during DNA replication prior to mitosis or meiosis. Chromosome Y by itself (when it is not replicating and there are no sister chromatids) is not acrocentric, as it wouldn't even have a centromere location.
When new cells are formed through the process of mitosis what is the number of chromosomes in the new cells?
there is no reduction of chromosome number.
When new cells are formed through the process of mitosis the number of chromosomes in the new cells is?
there is no reduction of chromosome number.
