Why is there a difference in the number of alleles for hemophilia and redgreen colorblindness between males and females?

There is a difference in the number of alleles for hemophilia and red-green colorblindness, because when a carrier of protanomaly has a child with a deuteranomalic man. Denoting the normal vision alleles by P and D and the anomalous by p and d, the carrier is PD pD and the man is Pd. The daughter is either PD Pd or pD Pd. Suppose she is pD Pd. Thanks...

In humans the alleles for hemophilia h is recessive. Which phenotype is displayed in an individual with the genotype XhY?
Genes that come together with different alleles are called _____.
An example of a sex-linked trait?
The best known examples in humans are color-blindness and muscular dystrophy. Males are the ones that are the most vulnerable because the Y chromosome is shorter than the X chromosomes that females have.
What is the difference between homozygosity and heterozygosity?
Homozygosity is the condition of having two identical alleles from the parents for a gene (AA). Heterozygosity is the condition of having two different alleles for a trait from parents (Aa).
What is the difference between a herezygous and a homozygous?
"Heterozygous" and "homozygous" are terms that refer to alleles, which, in genetics determine what trait, from which parent, will appear in the offspring. Alleles can be either Dominant or Recessive. Every organism has two alleles, which can both be dominant, both recessive, or one of each.So,If an organism heterozygous, it has one recessive and one dominant allele.If an organism is homozygous then both of its alleles are the same; you need to specify if they are homozygous recessive (both alleles are recessive) or homozygous dominant (both alleles are dominant).
How can you test for hemophilia?
Hemophilia must be diagnosed through blood tests. Family history of bleeding disorders can help narrow the tests needed to make an accurate diagnosis. If hemophilia is known in the patient's history and a bleeding disorder is suspected, it is probably the same, both in severity and type. Actual diagnosis however should only be bade following appropriate blood tests.
Why is there a difference in the numbers of alleles for hemophilia and colorblindness between males and females?
females have xand males dont
How many alleles for colorblindness do females have?
2
How many alleles for red-green colorblindness do females?
2
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
Is a carrier for colorblindness is colorblind?
Not necessarily. The allele for colorblindness is recessive. For a female, in order to be colorblind she must have to recessive alleles for colorblindness. Example: XcXc would be colorblind. XCXc would be a carrier for colorblindness, but not colorblind. For a male, because colorblindness is a sex-linked gene, he only needs one allele to be colorblind. Example: XcY is colorblind. XCY is not colorblind.

Genes that come together with different alleles are called _____.
What is the phenotype of an individual - XHY?
Genes that come together with different alleles are called _____.
In human the allele for hemophilia h is recessive. which phenotype is displayed in an individual with the genotype?
Genes that come together with different alleles are called _____.
Why is a son who receives the allele for color blindness from his mother always colorblind?
Being Colorblind means you recieved 2 recessive alleles from you parents. So that means the mother and father must of had 2 recessive alleles. Also Colorblindness is more common in males.
How is colorblindness genetic?
colorblindness is a genetic disorder.its gene is present on the x- chromosome.mutations or even combination of certain alleles( forms of a gene) can cause color blindnessmore males than females are affected to this disease as males require only one X-chromosome while females are suppossed to receive 2 X chromosomes for her to show the disorder.
A husband and wife have two sons one boy has a straight thumb while the other has a bent thumb what causes the difference?
The brothers have different alleles. They received different alleles from their parents
Difference between a gene and an allele?
The alleles are the different forms of the gene. This is simplified, but an example might be, if the gene is "eye color," the alleles would be "green, blue, brown, etc." The variations in the gene are the alleles.
