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...
What else can I help you with?
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 _____.
What is the difference between dominant and recessive alleles on the basis of DNA?
Dominant alleles override recessive alleles. For instance, if there is both a dominant allele and a recessive allele present the dominant allele will be the trait that you end up with. If you have two recessive alleles, then you will have the recessive trait. :::::::::::::::brown eyes overrided blue eyes, because they are darker:::::::::::::::::: usually a darker color overpowered/override the lighter ones....i dont really know why but my science teacher said so......
What is the difference between codominance and multiple alleles?
Codominance occurs when both alleles in a heterozygous individual are fully expressed, resulting in a phenotype that displays characteristics of both alleles, such as in blood type AB. Multiple alleles refer to the existence of more than two alternative forms of a gene within a population, allowing for a variety of genotypes and phenotypes, like the ABO blood group system where three alleles (A, B, O) determine blood type. While codominance describes the expression of alleles, multiple alleles describe the variety of alleles available for a trait.
What are traits caused by alleles on the sex chromosomes?
Traits caused by alleles on the sex chromosomes are known as sex-linked traits. Some examples include color blindness and hemophilia, which are more common in males because they only need one copy of the recessive allele to show the trait. This is due to males having only one X chromosome.
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.
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 _____.
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.
What is the difference between two alleles of the same gene?
The difference between two alleles of the same gene is that they are variations of the same gene that can result in different traits or characteristics. Alleles can be dominant or recessive, and individuals inherit one allele from each parent. These variations in alleles can lead to differences in physical traits or characteristics in an organism.
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.
What is the difference between alleles and genotype in terms of genetic inheritance?
Alleles are different forms of a gene that can be inherited from each parent, while genotype refers to the specific combination of alleles an individual has for a particular gene. In genetic inheritance, alleles determine the genotype of an individual, which in turn influences their traits and characteristics.
Is hemophilia codominance?
Hemophilia is not an example of codominance; it is an X-linked recessive disorder. This means that the gene responsible for hemophilia is located on the X chromosome, and males (who have one X and one Y chromosome) are more severely affected. Females can be carriers if they have one affected X chromosome but typically do not show symptoms unless both X chromosomes are affected. Codominance, on the other hand, refers to a genetic scenario where both alleles in a heterozygote are fully expressed, such as in blood type AB.
What are the differences between a long allele and a short allele in terms of genetic inheritance?
Long alleles and short alleles refer to different versions of a gene that can be inherited from parents. The main difference between them lies in the number of repeated sequences within the gene. Long alleles have more repeated sequences, while short alleles have fewer. This difference can affect how the gene is expressed and can influence traits or characteristics passed down from parents to offspring.
