The girl must have a copy of the gene on each X chromosome. This means that she must have a father who is colorblind and a mother who is either a carrier or is colorblind.

What must be true about the father?
he is color-blind
Is it more common for girls or boys to be color blind?
Boys. The gene that causes the varying degrees of color blindness is recessive and must be present on the X Chromosome. Since boys have only one X Chromosome, it is more common for boys to be color blind than girls. It is still possible for a girl to be color blind, but it is significantly rarer. The problem affects 8% of Caucasian males and 0.5% of Caucasian females.
Is there a control group in the dog color blind experiment?
Experiments that test to see if dogs are color blind must use a control group. Otherwise, the results are inaccurate and not scientifically valid.
What must occur for a girl to be colorblind?
Each parent must have the recessive allele for colorblindness.
Does the mother or father pass on the color blind trait?
It depends. If the child is male, the person to pass the trait on must be the mother. She may be a hybrid or color-blind herself for her to be capable of doing this. If the child is female, the father must be color-blind in addition to the mother being a carrier. Both have to donate the recessive gene to their daughter.
Can color blind people do explosive ordnance disposal?
No- not safely. Military ordnance uses color codes that an EOD tech must be able to interpret. Color blindness will interfere with that.
Are zebra's color blind?
No, but most mammals see only in black and white.
A male who is colorblind marries a heterozygous womanWhat percent of their total children will be color-blind?
NOW. Colourblindness we will assume, is a Sex-Linked Disorder. Hence, the sex chromosomes are involved in determinig the phenotypes of the children. XY --male XX--female XbY--colourblind male XBXb --normal female Cross: (parents) Xby * XBXb F1 progeny/offspring XBXb, XbXb, XBY, XbY 50 % of the children will be colourblind. This is a very simple question. You also need to clarify within the question if it is sex linked or autosomal.
What color is the thong that John Tucker puts on for a girl in John Tucker Must Die?
red
Father isn't colorblind mother is a carrier--one son is colorblind but the other is not how?
It is called x-linked alleles. It is rare for a female to have color blindness because the allele must be passed from both parents. Males only need one allele to be color blind.With the equation, color blind female and non-color blind male reproduce. Each son has a 50% chance of developing the disorder.
Must mitosis occur in budding?
