Does blindness affect a certain age group?
No colour blindness does not affect a certain age group it can affect anyone but usually you are born with colour blindness its not like usually as you grow older you go blind its completely different
What is a sex linked disorder caused by a recessive allele on the x chromosomes?
colour blindness
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.
Which chromosome is connected with colorblindness?
There are many chromosomes linked to colour blindness. If you are reading a really old text book or your teacher is a fossil and hasn't done any work since the 60's then they will say that colour blindness is linked to the sex chromosomes. More men than women have Red-Green colour blindness as the "dodgy" copy of the gene is on the X chromosome which males only get one copy of. Females have two X chromosomes and so are more likely to get at least one "good" copy of the gene. Yawn, this is a lie, well its outdated science which is just as bad. Currently around half the human chromosomes linked to colour blindness in one way or another.
Can color blindness affect people with autism?
No, of course colour blindness is not a form of autism. Autism is a neurological difference that results in social and communication problems, along with other issues like sensory problems and executive functioning problems. Autism isn't even comparable to colour blindness.
Why are men most likely to be color blind than women?
Men are not just 'likely' to be colour blind, they are the 'only ones' who can suffer from colour blindness. This is because colour blindness is cused by an x-linked recessive gene, that is it can occur only if a person carries 2 of these x-linked recessive traits. Now, females have one X and one Y chromosome,so in no way, they can have 2 X chromosomes.(exception-Klinefelter's syndrome, where thery is XXY trisomy) Only men can have 2 X-chromosomes. Hence, females can only carry the colour blindness gene, while men can 'suffer' from colour blindness.
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).
Can color blindness affect visual sight?
colour blindness will either make coloured things grey or it will make things hard to see. so yes,yes it does
