What is a sex linked disorder caused by a recessive allele on the x chromosomes?
colour blindness
What happens if a baby inherits two recessive genes for colour blindness?
If a baby inherits two recessive genes for color blindness, they will express the condition, as color blindness is typically an X-linked recessive trait. This means that if the baby is male, he will have color blindness if he inherits the recessive gene from his mother. If the baby is female, she would need to inherit the recessive gene from both parents to be color blind. In either case, the child will have difficulty distinguishing certain colors, commonly red and green.
Why are men most likely to be color blind than women?
Men are not just 'likely' to be colour blind, they are the 'only ones' who can suffer from colour blindness. This is because colour blindness is cused by an x-linked recessive gene, that is it can occur only if a person carries 2 of these x-linked recessive traits. Now, females have one X and one Y chromosome,so in no way, they can have 2 X chromosomes.(exception-Klinefelter's syndrome, where thery is XXY trisomy) Only men can have 2 X-chromosomes. Hence, females can only carry the colour blindness gene, while men can 'suffer' from colour blindness.
Color blindness is a recessive trait. The gene for color blindness is on the X-chromosome. The family tree below shows the trait of color blindness. The only unknown is the mother in the first generation?
(Apex Learning) She has at least one recessive color blindness allele.
Is color blindness a dominant or a recessive trait?
Color blindness is a recessive trait, meaning that an individual needs to inherit two copies of the gene for color blindness (one from each parent) in order to be color blind. If an individual inherits only one copy of the gene, they are considered a carrier and will not exhibit color blindness.
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
Explain how red-green color blindness is inherited?
well actually i very much disagree, i believe that color blindness is a sex-linked trait; therefore, a girl (written Xc ) who receives one recessive allele for one red-green blindness WILL NOThave the trait, however a boy who receives one recessive WILL be recessive.
Is color blind dominant or recessive?
recessive
In humans red green color blindness is?
An autosomal recessive trait
If night blindness is a recessive trait what should the phenotype of the couple's fourth child be?
If night blindness is a recessive trait, the couple's fourth child will exhibit the phenotype associated with night blindness only if both parents carry the recessive allele (i.e., they are either carriers or affected). If at least one parent has the dominant allele for normal vision, the child will not express night blindness. Therefore, the phenotype of the fourth child could be either normal vision or night blindness, depending on the genetic makeup of the parents.
