Can normal woman whose father was colorblind is married to a normal man the sun would be?

Option B: only 50\% of sons are color blind and the rest of the sons will be normal. Therefore, this is the correct option.

When a colorblind woman marries a normal man?

Complete answer: Option A: When a colorblind woman marries a man with normal eyesight, her daughters become carriers for the condition, and all sons become colorblind.

Can a colorblind father have a normal son?

A colour blind boy can’t receive a colour blind ‘gene’ from his father, even if his father is colour blind, because his father can only pass an X chromosome to his daughters.

What is the probability that a colorblind woman?

The most common form of color blindness is red-green color blindness. With this condition, the gene is passed from the parent to the child on the X chromosome. Globally, 1 in 12 males and 1 in 200 females are colorblind.

When the mother is normal and the father is colour blind the son will be?

A colourblind mother and normal father would have colour blind sons and carrier daughters. Daughters will be normal phenotypically but they will be carrier genotypically.

Where is the gene for color blindness located?

The genes that can give you red-green color blindness are passed down on the X chromosome. Since it’s passed down on the X chromosome, red-green color blindness is more common in men. This is because: Males have only 1 X chromosome, from their mother.

What is the genotype of a female with normal vision?

Any woman with normal vision could be XX or XX’. Since this woman has a colorblind son (genotype X’Y), she has to be XX’ (a carrier).

Can a female be color blind?

Color blindness affects an individual’s ability to see and distinguish differences in color. It largely affects men (more on that below). Ophthalmologists determine that as much as 10\% of the male population has diminished color vision, but women can have it as well (only about 1 in 200 women).

What is the genotype of a colorblind woman?

Problem 1: Audrei’s genotype

Female Genotype	Female Phenotype
XR XR	Normal Vision
XR Xr	Normal vision, “carrier”
Xr Xr	Red-green color blind

What happen when color blind girl and boy become parents?

If they have children with a man who is not color blind, then each daughter has a 50\% chance of being a carrier and each son has a 50\% chance of being color blind. The daughters without that blue X will not have color blind sons.

What are the chances of being colorblind if your father is colorblind?

If the female’s father was colorblind, and she has a children with a colorblind man, BOTH sons and daughters have a 50\% chance of being colorblind. If the female’s father was NOT colorblind, and she has children with a colorblind man, NEITHER sons nor daughters are likely to be colorblind.

What is the genotype of a person with colouredcolour blindness?

Colour blindness is a X-linked recessive disorder. Father transmit its X chromosome to the daughters so the colour blind father will inherit its affected X chromosome to the daughter. Hence, the genotype of carrier female will be (X c X) and that of normal man will be (XY). The carrier female and normal man will transmit the disease to 50\% sons.

Can a woman be a carrier of the color-blindness gene?

Women, being XX, can be color-blind (if both X chromosomes carry the color-blindness gene), carriers (if only one of their X chromosomes carries the gene), or completely free of the gene. So, we know that the woman is not color-blind, but that her father was. This means she is a carrier of the gene.

What is the most common cause of color blindness?

The most common form is caused by a defective gene on the X chromosome. A woman with normal color vision will have one normal X and one defective X chromosome. If she has a son with a colorblind male, the child will get only a Y chromosome from his father, and one X chromosome from his mother.
