X-linked recessive traits that are not related to feminine body characteristics are primarily expressed in the observable characteristics, or phenotype of men. This is due to the fact that men only have one X chromosome. Subsequently, genes on that chromosome not coding for gender are usually expressed in the male phenotype even if they are recessive since there are no corresponding genes on the Y chromosome in most cases. In women, a recessive allele on one X chromosome is often masked in their phenotype by a dominant normal allele on the other. This explains why women are frequently carriers of X-linked traits but more rarely have them expressed in their own phenotypes.

∙ 10y agoThe male sex genes are sequestered on the male sex chromosome (the Y chromosome in humans) while the female sex genes are located on the female sex chromosome (the X chromosome in humans).
In humans, males have the sex genotype XY (one X chromosome and one Y chromosome) while females have the sex genotype XX (two X chromosomes). Since females do not have the Y chromosome, they cannot produce male sex hormones (e.g. testosterone) while since males have only 1 copy of the X chromosome, they do not produce sufficient female sex hormone to manifest female secondary sexual characteristics.

∙ 6y agoIf you remember that males have XY chromosomes and females have XX you have the explanation, don't you?
A female has two chances for every trait - she could have a dominant trait that overpowers an unhealthy X-allele, but a male has only one X chromosome so whatever he gets is expressed.

Is colorblindness a dominant or recessive trait?
Color blindness is an inherited trait that can be passed on through reproduction but it has some peculiarities. It is recessive and not very prevalent in the gene pool. Because of this, color blindness does not appear very often in the population. In addition, it is a sex-linked gene on the X chromosome. Thus males only have one gene to express color vision. If it happens to be the recessive allele, then males are color blind. Females, on the other hand, must have both alleles recessive in order to be color blind.source: ciese.org/curriculum/genproj/activity35.html
How do you differentiate between males and females in a pedigree?
The males and females in a pedigree are differentiated by their sex organs.
Females are more lustful or males?
Females are more lustfull but they also have more resistance to control their lust
Do more females smoke than males?
I looked this up and the recent trends in smoking using graphs showed that males smoke more then females. I think....... I'm not sure. Yes. Females do smoke more.
A scientist studies a species of bird in which the males and females are about the same size. The females have plain colors and the males have bright colors. What can the scientist conclude about thes?
The scientist could conclude that the females choose mates.

Why is there a difference in the numbers of alleles for hemophilia and colorblindness between males and females?
females have xand males dont
Do females write french differently?
no
How many alleles for hemophilia do females have?
females have 2 alleles for hemophilia, (X^hX^H) and (X^hX^h) if H is the normal allele and h is the recessive allele for hemophilia
What does homozgous mean?
Homozygous means that you have identical alleles for a trait. Example: For females, both alleles are XX. Males are heterozygous, with XY.
How does a weight-training program affect males and females differently?
A weight training program can affect males and females differently because their bodies are built differently. Typically, men are able to lift more weight, and their bodies are also built differently in their structure.
Most copies of harmful recessive alleles are carried by?
individuals that are heterozygous for alleles
How will a weight training program affect males and females differently?
A weight training program can affect males and females differently because their bodies are built differently. Typically, men are able to lift more weight, and their bodies are also built differently in their structure.
What happens if your lezbian?
You like other females. You dress differently. It all depends on how much you change.
Do you believe male and females learn differently?
yes they do they learn differently because, females learn faster because they like to take there time with everything so that it is perfect while some men not all but some men half step wit some of there jobs.
