Genetics of color blindness

Can a female get color-blindness from her father’s side? The quick answer is that yes, a female can get a copy of the gene that leads to colorblindness from her father. In fact, the odds are nearly 100% that she’ll get that gene from her dad. However, to be colorblind, a woman needs to get two copies of the gene that leads to colorblindness — one from their mom and one from their dad. What this means is that if there is no history of colorblindness in your family, then odds are that your daughter will end up being a carrier for colorblindness. As a carrier, she’ll have one copy of the colorblind gene but not be colorblind herself. She’ll also have a 50% chance of passing the gene on to her kids. It is different for a son who can only get the gene that causes colorblindness from his mother and only needs one copy to be colorblind. These two different situations arise from the fact that the gene that causes colorblindness is found on the X chromosome and is recessive. As you probably know, boys have an X and a Y chromosome while girls have two X chromosomes — this is usually how one becomes male or female. Girls need two copies of the faulty gene copy because colorblindness is recessive to having color vision. What this means is that if you have one good copy of the gene that can cause colorblindness, then you won’t be colorblind. #ColorBlindnessDiseaseOrMedicalCondition #autosomal #DaughterCells #SisterChromatid #bloodType #PCR #punnettSquare #meiosis #doubleStrandedDNA #lawOfProbability #hardyWeinbergEquilibrium #colorblind #viruses #MolecularBiology #Primers #XChromosome #Nucleotide #Diploid #mutation #TumorCells #Haploid #GeneticExamQuestionsSolutions #GeneticsFieldOfStudy #gene #AminoAcids #CellCulture #cytosine #inheritance #NaturalSelection #Morphogenesis #ChromosomeArm
