Calico cats are nearly all females because the alleles for the different colors that appear are carried on the X chromosomes. Males are never multicolored because they can only carry one form of the a?
It is most common for calico cats to be female because the alleles for the different colors are carried on the X chromosome, which female organisms have two of (XX in female versus XY in males). Male calicos do exist and can be multicolored, but they are rare because they only carry one X chromosome.
Red-green colour blindness in human is caused by an X-linked recessive allele if the trait occur in 4 of the males in a population at Hardy-Weinberg equilibriumthen the frequency of this allele is?
If 4% of males in a population have red-green color blindness, then the allelic frequency is 4% in males and in females. If mating is random, then in females, 92.16% do not carry the allele on either X chromosome, 7.68% carry the allele on one X chromosome, and 0.16% carry the allele on both X chromosomes. We have the dominant allele with frequency p and the recessive allele with frequency q, so 0.9216 + 0.0768 + 0.0016 = p^2 + 2pq + q^2 = (p + q)^2 = (0.96 + 0.04)^2
Are males most likely to have an x-linked disorders?
Males are much more likely to be affected by an x-linked disorder because they only have one copy of the x-allele, so if they carry an abnormal version, it will be expressed. On the other hand, since women have two copies of the x-allele, they would need two copies of the abnormal gene to show the disease.
More males suffer from red-green color blindness than females because?
It is due to a recessive allele on the X chromosome, in which women have 2 and men have 1. Women kinda have a "back-up" to cover the defected X, but males don't.
Which is true of autosomal recessive diseases a. The disease can skips generations b. Males and Females have an equal chance of inheriting the mutant allele c. Only Males inherit the?
only A and B
What is it an example of when calico cats are mostly females because the allele for different covers is carried on the X chromosome so males are never multi colored?
sex-linked inheritance
Sex linked traits are primarily found in?
Males, because they have one X chromosome, in which the traits are carried on. Therefore, if they have one allele they will have that trait because they do cannot have another allele to affect it.
Colorblindness is more common in males than in females because?
the allele for colorblindness is recessive and located on the X chromosomes
Under what condition is a single recessive allele expressed in a male?
Recessive alleles are expressed if there is no dominant allele (of the same gene) present. This can be for two reasons, because the other allele is also recessive, or because there is no other allele (such as X-linked genes, which males only have one copy of).

Why are female carriers?
Females carry two X chromosomes; males only carry one. A female carrier carries a defective recessive allele for a gene on the X chromosome. Thus, the female will not be affected because she still has a copy of the dominant allele. However, if she has any male children, that child will be affected because males inherit their X chromosome from their mothers.
Why are sex linked traits more common in males rather than females?
because males only have one X chromosome, and don't have the stuff to keep the resessive allele away, only one fighter.

The allele for color blindness is found on the x chromosome more males suffer from red-green color blindness tha females because?

Why are sex link traits more common in male than females?
Sex-linked traits are more common in males than in females. This because recessive allele in the X chromosome and produces the trait in males.
