Which is the male genotype in the ZW sex chromosome sytem?

In the ZW sex chromosome system, the male genotype is typically represented as ZZ. In this system, females have a ZW genotype, while males possess two identical Z chromosomes, resulting in the ZZ configuration. This system is commonly found in birds, some reptiles, and certain insects.


A trait that can only be inherited by a male would be a?

Y-linked (sex-linked) - it would only be found on the Y chromosome - and therefore it is impossible for a female to inherit this.X-linked recessive traits are much more likely to occur in males, but it is still possible for a female to have them (if they have a defective gene on both their X chromosomes).


How does hemophilia progress?

Hemophilia is a recessive allele condition. Men can get hemophilia alot easier than women as the allele is found on the XY Chomosome pair. With men. they do not have the extra "tail" on the Y chromosome compared to the XX with a female. If the person has the recessive allele on the X chromosome and this person is male, they will be a hemophiliac as they do not have a 'pair' allele which could be dominant to stop the condition expressing itself. On a female, if there is a recessive (hemophilia) allele on one of the X chromosomes but on the other is a Dominant (normal) allele then she will be a carrier of the faulty gene but will not suffer from the condition herself. If the female have a recessive (faulty) gene on each of the XX chromosomes, then she will be a sufferer of the disease.


What is a z chromosome?

A Z chromosome is a sex chromosome in a species in which the female is heterogametic (i.e. has different sex chromosomes). The counterpart is the W chromosome. In an XY system (e.g. humans), the male is heterogametic, XY, and the female is homogametic, XX. In a ZW system, the male is homogametic, ZZ, and the female is heterogametic, ZW. Examples of species with ZW systems include all birds, many reptiles, fishes and some insects.


Which chromosome is found only in males?

Y chromosome

Why is hemophilia more common in males than women?

this disease is caused by a recessive allele that is found only on the x chromosome. a human female has two x chromosomes. a human male only has 1 x chromosome. therefore, a male needs only one recessives allele to have hemophilia, while a female needs two recessive allele. as a result, hemophilia is much more common in males.


Is colorblindness genetic?

Yes. It is a sex-linked recessive trait found on the X chromosome.

An inactivated X chromosome would be found in the nucleus of a female somatic cell.

What do you get when you cross a male hemophiliac with a female hemophiliac?

The gene for hemophilia A is found on the X chromosome (it is a sex-linked recessive disorder). Women have two X chromosomes and men have one X chromosome. A woman with hemophilia (very rare) would have the mutated gene on both of her X chromosomes. This means that all of their children, both male and female would have hemophilia.


Cystic fibrosis is it monosomy 21?

No. Cystic fibrosis is an autosomal recessive disease caused by mutations found on chromosome 7.


What chromosome number is hemophilia on?

Hemophilia is a Sex-linked genetic disorder. It is found on the X chromosome of chromosome 23.A carrier for Hemophilia(represented by H(dominant) or h(recessive)) would look like this:XHXh(Female)*Males are not carriers for hemophilia-They are either affected or they're not*An affected person would look like this:XhXh(Female) XhY(Male)Someone who is neither a carrier nor affected would look like this:XHXH(Female) XHY(Male)

What is a is a sex-linked trait?

If a gene is found on the X chromosome ( and, less commomly on the Y chromosome), it is said to be a sex-linked trait. Because the gene controlling the trait is located on the sex chromosome, sex linkage is linked to the gender of the individual. Usually such genes are found on the X chromosome. The Y chromosome is thus missing such genes (See Diagram above.). The result is that females will have two copies of the sex-linked gene while males will only have one copy of this gene. If the gene is recessive, then males only need one such recessive gene to have a sex-linked trait rather than the customary two recessive genes for traits that are not sex-linked. This is why males exhibit some traits more frequently than females.


What determines if you are male or female?

TDF (testicular determining factor) is a gene found on the Y chromosome that will determine if one is male or female. If it is present, one is a male. If it is absent, one is a female.

Is the genotype the outward expression of a gene?

NO NO NO!!!!!a genotype refers to the actual makeup of the gene, as in the type of alleleuppercase refer to dominant genes, lowercase refer to recessive genesan expressed gene regardless of whether it is dominant or recessive is expressed in the PHENOTYPE which is the physical traits observable caused by the genotypePhenotype is what your question should be changed to and then your answer will be yes
