That happens in Ana phase.When a chromosome is not split in centromere,a chromosome fully moves to a daughter cell.

How does the chromosome number gets reduced in anaphse1?

During anaphase I of meiosis, homologous chromosomes are separated and pulled to opposite poles of the cell. This process results in the reduction of the chromosome number because each daughter cell will receive only one chromosome from each homologous pair, effectively halving the chromosome number compared to the original diploid cell. Consequently, if the original cell has a diploid number of chromosomes, the resulting cells will be haploid.


How many chromosomes dose each parent pass to their offspring?

When a parent is going to have an offspring the offspring only gets half a chromosome from each parent, they combine to make one chromosome then that chromosome gets copied until there are 23 pairs of chromosome's. This is how you get your features.


What trimester is a gender of a fetus determined?

When the sperm meets the egg. The sprem contains the gender in the form of an x or y chromosome


Does Meiosis reduce the number of chromosomes within a cell by one-half?

Meiosis: Each daughter cell's chromosome number gets halved.---Haploid cells(n)Mitosis: Each chromosome number stays the same.------------------Diploid cells(2n)


What is it when each gamete gets one gene for each trait?

This is known as the law of segregation in genetics, which states that each parent donates one of two alleles for each gene to their offspring. As a result, each gamete (sperm or egg) receives only one gene for each trait. This process ensures genetic diversity and the random assortment of traits in offspring.

What is a chromosome called when it gets lost during mitosis?

" gets lost "I think you are describing a nondisjuction event where the chromosomes are not properly pulled apart to their proper positions by the mitotic spindle.

What stage of cell division would down's syndrome occur?

Down syndrome (trisomy 21) occurs when a gamete carrying an extra copy of chromosome 21 is involved in a fertilization event.The gamete (whether sperm or oocyte) has an extra copy of chromosome 21 because of something called NONDISJUNCTION. This happens when a chromosome gets pulled to the wrong daughter cell.This can happen either in meiosis I or meiosis II.If nondisjunction happens in meiosis I, 2 gametes will be n+1 (have the extra copy of 21) and the other 2 gametes will be n-1 (will have NO copy of 21)If nondisjunction happens in meiosis II, 2 gametes will be normal, one will be n+1 and one will be n-1.


How does someone with Down syndrome get that extra chromosome?

During meiosis homologous chromosomes are separated and only one copy of each chromosome goes into the gamete. If they aren't separated correctly, both copies may go into the gamete. After fertilisation, the embryo will contain 3 copies of that chromosome. If this occurs with chromosome 21, it will result in Down Syndrome.


Because the zygote gets half of its gentic code from each gamete the human offspring?

results in the 46 chromosomes that we have?


Why does a gamete only contain 23 in the human body?

You get the other 23 from the opposite sex. The semen and the egg combines and gets 46 chromosomes. If each gamete contained 46 chromosomes, the zygote would contain 92 chromosomes.


What caused anomaly when one daughter cells gets two copies of a chromosome?

The process by which a daughter cell accidentally get two copies of a chromosome is called "nondisjuction".

Why the female gamete bigger than male gamete?

The female gamete is most likely bigger than the male gamete because it is the cell that will eventually provide the nutrients for the organism that will begin to grow there. It will start forming into a multicellular organism and therefore needs to be big enough to divide.


Each gamete gets one gene from each trait?

In meiosis, each gamete receives one allele for each gene, ensuring genetic diversity and random assortment of traits in offspring. This process helps create unique combinations of genes in gametes, leading to variability in traits among individuals.


What causes the abnormality in chromosome numbers in people with down syndrome?

It is most commonly caused by increased maternal age.Add: It is the result of nondisjunction of the 21st chromosome pair, in which the pair fails to separate, so that one cell gets an extra copy of chromosome 21.


Why males are afflicted with hemophilia more than females?

Because males have the chromosome XY. And Hemophilia attacks the X chromosomes, so if the disorder gets to the X chromosome of the male, it doesnt have another X chromosome to back it up like females do.(XX)
