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.
What else can I help you with?
How abnormal number of any chromosome gets into gamete?
That happens in Ana phase.When a chromosome is not split in centromere,a chromosome fully moves to a daughter cell.
Which one of the reactant for cellular respiration gets oxidized and which one gets reduced?
During cellular respiration, glucose gets oxidized to form carbon dioxide and water, while oxygen gets reduced to form water. Glucose loses electrons and hydrogen atoms, which are transferred to oxygen during the process, resulting in the reduction of oxygen to water.
How does fertilization affect the chromosome number of a zygote?
Sperm contains 23 chromosomes. An egg contains 23 chromosomes. The zygote (a fertilized egg) contains 46 chromosomes. Yet, it is also important to consider that the egg completes meiosis before joining with the sperm, thereby shedding half of its 46 chromosomes into a polar body that adjoins the zona pelucida lining.
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
How abnormal number of any chromosome gets into gamete?
That happens in Ana phase.When a chromosome is not split in centromere,a chromosome fully moves to a daughter cell.
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 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".
How do you get chromosome?
boy meets girl, girl meets boy the baby gets chromosomes
Which one of the reactant for cellular respiration gets oxidized and which one gets reduced?
During cellular respiration, glucose gets oxidized to form carbon dioxide and water, while oxygen gets reduced to form water. Glucose loses electrons and hydrogen atoms, which are transferred to oxygen during the process, resulting in the reduction of oxygen to water.
How do you reduce isnophilia?
Eosinophilia is reduced when the cause of it gets reduced. That is when allergy or infection subsides the eosinophil count subsides.
Can the number of us senator speak from any state be reduced?
Each state gets 2 senators. That number does not change. The number of members of the House of Representatives will change, based on population changes- but Senators will stay at 2 per state.
Does a oxidized agent increase its oxidation number?
Yes, an oxidizing agent increases its oxidation number as it gains electrons during a redox reaction. This means it gets reduced by accepting electrons from the reducing agent.
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)
How is the X chromosome inactivated?
X chromosome inactivation is a process that occurs in female mammals where one of the X chromosomes in each cell is randomly inactivated. This ensures that both males and females have similar levels of X chromosome gene products. The inactivated X chromosome condenses into a structure called a Barr body.
Why is pulmonary circulation reduced in the fetus heart?
Pulmonary circulation reduced in the human fetus because the baby gets its oxygen from its mother & it does not breath on its own.
