What element is responsible for determining male sex in humans?
The element responsible for determining male sex in humans is the Y chromosome.
What portion of the human Y chromosome is homologous to the human X chromosome?
The pseudoautosomal regions (PARs) at the tips of the Y chromosome are homologous to regions on the X chromosome. These PARs are responsible for pairing and recombination between the X and Y chromosomes during meiosis. About 5% of the Y chromosome is homologous to the X chromosome in humans.
Most sex-linked genes are found on which chromosome x y?
Many sex-linked genes are found on the X chromosome. More than 100 sex-linked genetic disorders have now been mapped to the X chromosome. The human Y chromosome is much smaller than the X chromosome and appears to contain only few genes.
Who is responsible for sex determination in humans the male or the female parent?
The sex determination in humans is determined by the male parent through the presence of the X or Y chromosome in the sperm. The female parent always contributes an X chromosome. If the sperm carries an X chromosome, the resulting offspring will be female (XX), and if it carries a Y chromosome, the offspring will be male (XY).
What enzyme is coded forin the chromosome of bacteria?
One common enzyme coded for in the chromosome of bacteria is DNA polymerase, which is responsible for replicating the bacterial DNA during cell division. This enzyme is essential for maintaining the integrity of the bacterial genome.
A segment of chromosome responsible for a particular characteristic?
DNA or genens these are the segments of the chromosome.
What are chromosome responsible for?
Life man yeah dude
What genes are responsible for neuronal migration disorders?
The most well characterized genes include DCX on the X chromosome, responsible for double cortex syndrome, and LIS1 on chromosome 17, the first gene identified for lissencephaly.
What element is responsible for determining male sex in humans?
The element responsible for determining male sex in humans is the Y chromosome.
What portion of the human Y chromosome is homologous to the human X chromosome?
The pseudoautosomal regions (PARs) at the tips of the Y chromosome are homologous to regions on the X chromosome. These PARs are responsible for pairing and recombination between the X and Y chromosomes during meiosis. About 5% of the Y chromosome is homologous to the X chromosome in humans.
For what are genes on the y chromosome responsible?
Genes on the Y chromosome are responsible for male sex determination and other male-specific traits. They play a crucial role in the development of male reproductive organs and secondary sexual characteristics.
In humans the shorter of the sex chromosomes?
In humans, the Y chromosome is noticeably shorter than the X chromosome.
What chromosome is affected in fabry disease?
The allele that is responsible of Fabry Disorder/Disease is located on the X chromosome and is the only lipid storage disorder identified as being sex linked.
How can duplication of a chromosome of the first pair produce a double head and at the same time affect the wing pigmentation and body organism?
There are multiple genes encoded by this chromosome. The duplication of the chromosome might have dysregulated multiple genes that affect the patterning of the head and body and affect wing pigmentation. On the other hand, one gene might be involved in all these processes. For instance, patients with Down syndrome have three copies of chromosome 21, resulting in developmental issues but also an early onset of Alzheimers Disease.
Which parent regardless of the phenotype is responsible for color blindness in a son?
Color blindness is typically inherited in an X-linked recessive pattern. This means that a son inherits his X chromosome from his mother and his Y chromosome from his father. Therefore, regardless of the mother's phenotype, she is the parent responsible for passing on the X chromosome that may carry the gene for color blindness, while the father contributes a Y chromosome. If the mother is a carrier or affected, there is a chance for the son to be color blind.
How many chromosome 7 s are there in the human nucleus?
Two, one from each parent. Over 90,000 genes are found on each chromosome and are mostly responsible for protein productions.
Most sex-linked genes are found on which chromosome x y?
Many sex-linked genes are found on the X chromosome. More than 100 sex-linked genetic disorders have now been mapped to the X chromosome. The human Y chromosome is much smaller than the X chromosome and appears to contain only few genes.
