What is a DNA code for one hereditary trait is called?
The DNA code for one hereditary trait is called a gene.
What kind of non Mendelian trait is color blindness?
Color blindness is an example of an X-linked recessive trait, which is a type of non-Mendelian inheritance. This means that the gene responsible for color blindness is located on the X chromosome, and the trait is more commonly expressed in males than females.
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.
In a survey 16 women out of 20 000 were found to be colour blind What is the expected frequency of colour blind males in this population?
Not all forms of color blindness are hereditary. There are three distinct types of hereditary color blindness, each with different frequencies in the human population, and with distinct genetic causes. Red-green color blindness is more common among males than females, but blue-yellow color blindness is not. Talking about color blindness in general, there is no reliable ratio of male-to-female prevalence.
How does linkage affect the inheritance of traits?
As in sex linkage?Well if a trait is sex linked then one gender may be more likely to have that trait than the other. For example, colour blindness is a trait that is linked to the X chromosome. So males are more likely to be colour blind than females because the colour blindness gene is recessive and males only have 1 X chromosome where as females have 2 X chromosomes. Though females may be carriers of the colour blindness chromosome, therefore potentially passing it on to their children (son or daughter).
How do you cure color blindness in humans?
you cannot cure Colour blindness is hereditary, it's in your genes.
Name one sex linked trait and describe how it is inherited?
Colour blindness
What age dose colorblindness start in kids?
Colour-blindness is hereditary... Sufferers have the condition from birth.
What is colour blindness recessive?
Yes, Color Blindness is recessive, Not dominant. :)
Why is red-green color blindness not contagious?
Colour blindness is a usually a genetic (hereditary) condition (you are born with it). Red/green and blue colour blindness is usually passed down from your parents. The gene which is responsible for the condition is carried on the X chromosome and this is the reason why many more men are affected than women
What is a DNA code for one hereditary trait is called?
The DNA code for one hereditary trait is called a gene.
How do people contract the disease color blindness?
Color blindness is hereditary and non-communicable.
Does colour blindness affect male and females equally?
AnswerWomen have the sex chromosomes XX, while men have the chromosomes XY. The gene for normal colour vision is found on the X-chromosome. If a woman has one X-chromosome with the gene and one without it, she will not be colour blind. On the other hand, a man with an X-chromosome that is missing the gene has no 'backup'. He will definitely be colour blind. Colour blind women have both X-chromosomes missing the colour vision gene. This is less probable mathematically than having just one X-chromosome missing the gene.
Is persistence a hereditary trait?
Yes.
Is blindness hereditary?
Yes, it can be hereditary...but it depends on a lot of things.
Is athletic ability a hereditary trait?

What are dominant traits?
dominant trait is a genetic trait which may cause a hereditary condition
