The Y chromosome carries the SRY gene (Sex-determining Region Y) which is essential for male sexual development. The SRY gene triggers the development of male sex characteristics during fetal development.
Chromosome 5.The gene is known as TERT (or, in humans, hTERT) and is the most distal gene on the short arm of chromosome 5 (5p). Its location is 5p15.33. For more detail, see the link below.
Several genetic disorders are caused by genes on the X chromosomes.
A woman carrying a gene for hemophilia is typically a carrier with one X chromosome carrying the hemophilia gene and one X chromosome carrying the normal gene. When she is mated with a normal male who has one X chromosome and one Y chromosome, there is a 50% chance that the son will inherit the X chromosome carrying the hemophilia gene from the mother. Since males have only one X chromosome, if they inherit the hemophilia gene, they will express the disorder.
Most sex-linked traits are found on the X chromosome because males have only one X chromosome, so any gene on the X chromosome will be expressed in males. In females, who have two X chromosomes, one X chromosome can compensate for any harmful gene on the other X chromosome.
The defective gene in Hurler syndrome is located on chromosome 4. This gene carries instructions for making an enzyme called alpha-L-iduronidase, which is essential for breaking down certain complex molecules in the body. When this gene is mutated, the enzyme is deficient, leading to the accumulation of harmful substances in the cells.
The Y chromosome carries the SRY gene (Sex-determining Region Y) which is essential for male sexual development. The SRY gene triggers the development of male sex characteristics during fetal development.
False. A mutation refers to a change in the DNA sequence of a gene or chromosome, not the specific part of a chromosome that carries information about a trait.
Chromosome 5.The gene is known as TERT (or, in humans, hTERT) and is the most distal gene on the short arm of chromosome 5 (5p). Its location is 5p15.33. For more detail, see the link below.

no. what you described is a gene. a mutation is a change in the DNA which can sometimes change a gene
A gene is a part of the chromosome what is linked to your DNA it carries the proteins which make you, you! Factors that control traits.

nucleus → chromosome → gene
Smallest to largest: Gene (a place on a chromosome); chromosome (there are 46 in human cells); and DNA (because it accounts for all the genetic material in a cell).
The Y chromosome is the chromosome that determines male sex. It carries the SRY gene that triggers the development of male characteristics during embryogenesis.
When a gene is linked to a chromosome, it means that the gene is physically located on that chromosome. This means that the gene is inherited along with the chromosome it is located on, and may be inherited together with other nearby genes on the same chromosome.
