Is color blind dominant or recessive?
recessive
Which parental pair could produce female with color blindness?
X' = color blindnessX'X'-- X --X'Yis a cross that could lead to a color blind female as the mother is homozygous recessive and the father's X chromosome is the recessive color blind trait.
If a male has red -green color blindness show his genotype and explain who be inherited his recessive allele form.?
A male with red-green color blindness has the genotype X^cY, where X^c represents the X chromosome carrying the recessive allele for color blindness. He inherited the recessive allele from his mother, who must have at least one X chromosome with the color blindness allele (either X^cX or X^cY). Since males inherit their X chromosome from their mothers and their Y chromosome from their fathers, the mother's genotype determines whether the son will express the condition.
Explain why the incidence of color blindness is higher in male than females?
Overall, colorblindness is much more common in males than females due to the fact that it is a sex-linked trait. The gene for colorblindness is carried on the X chromosome. Since this is a recessive condition, males will be more likely to express it due to the fact they only have one X chromosome while the females have two.
Is Red-green color blindness an X-linked recessive disorder?
Yes, red-green color blindness is typically an X-linked recessive disorder. This means that the gene responsible for red-green color blindness is located on the X chromosome, and individuals who inherit an abnormal gene on their X chromosome are more likely to express the trait if they are male, as they have only one X chromosome.
Is the color blindness gene also present on the Y chromosome?
No - the colour blindness gene is only found on the X chromosome.
Is color blind dominant or recessive?
recessive
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.
Sex-linked trait in men?

X' = color blindnessX'X'-- X --X'Yis a cross that could lead to a color blind female as the mother is homozygous recessive and the father's X chromosome is the recessive color blind trait.
Where is the color blindness gene found?
It is found on the non homologous part of the X chromosome.

The allele for color blindness is found on the x chromosome more males suffer from red-green color blindness tha females because?
Plato Users: A and B.
What causes color blindness genetically?
The majority of affected individuals are males. Females are carriers, but are not normally affected. This indicates that the X chromosome is one of the locations for color blindness.

How is colour blindness passed on?
Color blindness is primarily an inherited genetic condition, passed down through specific genes on the X chromosome. It is more common in males because they have only one X chromosome, meaning if the gene is present on that chromosome, they will exhibit color blindness. Females are less likely to be color blind because they have two X chromosomes, so they would need to inherit the gene from both parents to be affected.
