What else can I help you with?
If a diploid cell containing 28 chromosomes undergoes meiosis how many chromosomes will each daughter have?
In mitosis, the daughter cells each have the same number of chromosomes as the parent cell.
Why is meiosis necessary in organism that carry out sexual reproduction?
This is necessary because it keeps the numbers of chromosomes the same through every generation. As you might know 1 extra or 1 missing chromosome is harmful for an individual.
What chromosomes can be affected by changes in chromosome numbers?
Any chromosome can be affected by changes in chromosome numbers. This can include trisomy (three copies of a chromosome), monosomy (one copy of a chromosome), or other abnormalities such as deletions or duplications. These changes can lead to genetic disorders or abnormalities.
How many numbers of chromosomes in new cells in meiosis?
In meiosis, a single diploid cell undergoes two rounds of division, resulting in four haploid cells. Each of these new cells contains half the number of chromosomes of the original cell. For example, if the original cell has 46 chromosomes (as in humans), each of the four new cells will have 23 chromosomes.
Why do gametes have n numbers of chromosomes but not 2n?
Gametes are produced by the type of cell division called meiosis. During meiosis the number of chromosomes are halved. So if a cell starts off with 2n chromosomes and divides by meiosis the new cells will end up with n chromosomes.
What happens to the chromosome numbers during meiois?
During meiosis, the chromosome number doubles because the cells replicate their DNA and split into two cells in meiosis I and in meiosis II, they replicate DNA and split once again, to form four cells.
What is the difference between primary and secondary nondisjunction?
primary can happen in meiosis and as a result produces gametes with more than or less than the original number of chromosomes. secondary occur in an individual whose chromosomes already has the wrong number because of non disjunction.
Does meiosis reduce chromosome numbers?
Yes - the daughter cells produced in meiosis (gametes) have half the number of chromosomes as those in the original cell. This is why meiosis is referred to as 'reduction division'. However, as meiosis produces cells which are involved in sexual reproduction - the chromosome number in the species remains constant. This is because when the two gametes combine, the resulting organism has the correct number of chromosomes (half from each gamete).
The hybrid germ cells of a mule cannot undergo meiosis because?
Mules does not have even chromosome number. They have 63. During meiosis, chromosomes are paired up, one from the Mom and one from the Dad. Since mule does not have even chromosome number, pairing of homologous chromosomes are impossible, so meiosis is disrupted and no sex gametes are able to form.
If a diploid cell containing 28 chromosomes undergoes meiosis how many chromosomes will each daughter have?
In mitosis, the daughter cells each have the same number of chromosomes as the parent cell.
Is a hinny sterile?
Chromosome numbers are different that is why they cannot go under meiosis and can't produce offspring. It is known as interspecific (between two species) hybrid . They are sterile some examples-Mules,Hinny
Why is meiosis necessary in organism that carry out sexual reproduction?
This is necessary because it keeps the numbers of chromosomes the same through every generation. As you might know 1 extra or 1 missing chromosome is harmful for an individual.
How and why are chromosome numbers reduced during meiosis?
It reduces half the number of chromosomes because its spliting up a cell and that also splits into to parts. The most chromosomes human can have is 46 so ya. UNICORNS R AWESOME AND SO IS JOEY GRACEFFA
Do you see a place where problems could arise during Meiosis?
During the anaphase phase of meiosis, there can be non-dysjunction. This is when the spindle fibres do not effectively pull apart the chromosomes, leading to the cells having unequal numbers of chromosomes (ie. 3 and 1 rather than 2 and 2). An example of this is Trisomy 21, which is when there is non-disjunction of the 21st chromosome in either Anaphase I or Anaphase II. This causes Down's syndrome.
What chromosomes can be affected by changes in chromosome numbers?
Any chromosome can be affected by changes in chromosome numbers. This can include trisomy (three copies of a chromosome), monosomy (one copy of a chromosome), or other abnormalities such as deletions or duplications. These changes can lead to genetic disorders or abnormalities.
Why is a mule infertile?
A donkey and a mule have different chromosome numbers. When meiosis occurs (the creation of egg and sperm) the chromosome numbers halve and half of the genetic material is given to each of the two new cells created. However in the case of mule, their normal body cells have an uneven chromosome number so this cannot occur, therefore they can't make eggs or sperm
If a cell has 14 chromosomes and undergoes meiosis how many chromosomes will each cell have?
The daughter cells will have 14 chromosomes, the same as the parent cell. Not only are the numbers of chromosomes the same, but they are also genetically identical to each other and the parent cell.
