What condition occurs when a human zygote has 47 chromosomes?
A human zygote with 47 chromosomes has a condition called trisomy, specifically trisomy 21 if the extra chromosome is chromosome 21. This results in Down syndrome, a genetic disorder characterized by intellectual disability and physical abnormalities.
What happens if a egg cell has 24 chromosomes and is fertilized by a sperm cell containing 23 chromosomes.?
The resulting zygote would have 47 chromosomes, which is an extra chromosome compared to the normal human chromosomal number of 46. This condition is called trisomy and can lead to genetic disorders such as Down syndrome.
What might happen if human chromosomes did not separate?
well if human chromosomes number 21 does not separate during fertilization the baby will be with down syndrome. at fertilization of the egg with a normal sperm the zygote contain three chromosome number 21 (trizomic 21) hence the zygote contain 47 chromosome instead of 46.
How many chromosomes are present in each cell in this human?
There are 46 chromosomes in a normal human cell and 23 in the sex cells. People with down syndrome has 47 chromosomes.
How many chromosomes would be in a zygote if the bird has 30 chromosomes?
A zygote is a fertilized egg cell, so it is diploid and thus has a full set of DNA. If the adult has 30 pairs of chromosomes, the zygote would have 30 pairs. If there are 30 chromosomes, then the zygote will have 60 (30 from the mother and 30 from the father). It comes down to whether you meant individual chromosomes or pairs of chromosomes.
What type of disorders are karyotyping used to diagnose?
Chromosomal disorders can be observed in a human karyotype. It can show whether there are extra chromosomes, or missing chromosomes, or malformed chromosomes, or whether chromosomes have extra pieces, or missing pieces.
How any chromosomes are in each human cell?
If you mean how many; there are 46, or 23 homologous pairs. There are 22 autosomal pairs and the sex chromosomes (X and X/Y). This can vary in some disorders, such as Down Syndrome, Turner Syndrome, Klinefelter's Syndrome, and Triple X Syndrome.
What is the genetic disorder for having three 21 chromosomes?
down syndrome
What is the total amount of chromosomes do down syndrome children have?
21 chromosomes
What chromosomes do you get an extra copy for in humans that results in Down syndrome?
Down Syndrome is caused by a triplication of the 21st chromosome.
What is the diagnosis if you have 92 chromosomes?
down's syndrome
All are conditions associated with changes in human chromosomes numbers except A Down Syndrome B Turner Syndrome C Klinefelter Syndromme D Jacobs Syndrome E Fragile X Syndrome?
The answer is D. Jacobs Syndrome
