What happens during meiosis that results in a defect characterized by the deletion of a chromosome?
what happens during meiosis that results in a defect characterized by the deletion of chromosomes
Is hemophilia a defect?
Hemophilia is a genetic mutation of the sex-linked X chromosome.
Which chromosomal defect is caused when part of a chromosome breaks off at either end and attaches to another chromosome?
The chromosomal defect you are describing is known as a translocation. In a translocation, a segment of one chromosome breaks off and is reattached to a different chromosome, which can lead to genetic imbalances and various genetic disorders. This type of defect can occur in both somatic cells and germ cells and is often associated with certain cancers and congenital conditions.
Who would be a sex-linked recessive defect?
Hemophilia, a blood clotting disorder, is an example of a sex-linked recessive defect. It occurs more commonly in males because the gene for hemophilia is located on the X chromosome. Females are usually carriers of the gene but are less likely to exhibit symptoms.
What is difference between shotkey defect and frankel defect?
1).schottky defect arises due to departue of ions (both cation and anion in equal ratio) from crystal lattice leaving holes that favour conductivity. The equal no of ions depart because to maintain the electrical neutrality of crystal. It was discovered by walter.H schottky in 1930. But in frenkel defect ions(cations) are missing from there normal lattice site and occupying an interstitial site between the lattice points. They dont depart from crystal lattice. Because no departure occure so crystal remain electrically neutral. It was discovered by Yakov frenkel in 1926. 2) schottky defect is only vacancy defect but frenkel defect is vacancy as well as interstitial defect. 3). Schottky defect decreases density and strength of the crystal. But frenkel defect doesnt affect density. 4).schottky defect is shown by the ionic solids having high coordination no and approx. same size of cation and anion(i.e r+ve/r-ve approaches to 1) While frenkel defect is shown by the compound having low coordination no and size of anion larger than cation(i.e r+ve/r-ve approches the minimum value).

What kind of defect is CGD?
recessive defect meaning that both copies of the chromosome must have the defect before it can be expressed. Females who have one X chromosome without the defect do not get this disease. Males, since they only have one X chromosome, get the disease
What is an example of a birth defect in which there is abnormality in the chromosome structure?
Down's Syndrome is an example of a birth defect characterized by an abnormality of the chromosome structure.

What does Congenital heart?
"Congenital" means present at birth. So, a congenital heart defect is a defect (structural anomaly) that is present at birth. 1 in 100 babies are born with a congenital heart defect.
Is hemophilia a defect?

What is the chromosomal defect that causes Prader Willi?
its when seven genes chromosome 15 are missing or ununexpressed on the paternal chromosome.
What conditions increase an unborn baby's chances of undergoing intrauterine growth retardation?
Exposure to an infection, including German measles (rubella), cytomegalovirus, tuberculosis, syphilis, or toxoplasmosis; A birth defect (like a severe cardiovascular defect); A chromosome defect
What is defect cascading?
Defect cascading explains how one defect leads to other defects. For Example, employee application salary calculations are not correct when totaling Basic, Tax and Gross, so for this issue defect raised. In this case other modules will block and also same defect will exists in all those modules due to this defect. This is called Defect Cascading.
What congenital anomaly?
a defect of the body present from birth
