What allele combination would will have a colorblind child?
carried on the x chromosome
What describes allele that causes color blindness?
It is carried on the X chromosomeIt is carried on the X chromosome
Is a chromosome a allele?
No. An allele is the tip of a chromosome.
Sex linked traits are primarily found in?
Males, because they have one X chromosome, in which the traits are carried on. Therefore, if they have one allele they will have that trait because they do cannot have another allele to affect it.
What is the condition that is carried on the x chromosome whereby an affected mother passes the condition to all sons?
for son x chromosome comes from mother and y chromosome from father. If the mother had both allele got affected then the transfer of disease is 100 %. If only one allele is affected then 50% possibility of son getting affected
Why does selection act faster against a harmful dominant allele than a harmful recessive allele?
The harmful dominat allele has a better chance of eliminating a population.
What an allele?
An allele is an alternative form of a gene that is found at the same location on a chromosome.
What is dominant the X or the Y?
An allele on either X or Y could be dominant over the allele on the other chromosome, but it is more common for the allele on the X to be dominant, because the Y chromosome is much smaller than the X and contains fewer genes. In many cases, there is no allele for a particular gene on the Y chromosome; so whatever allele is on the Y will be dominant.
Is the Prader Willi Syndrome carried by males or females?
it is carried by both males and females but technically the cause of it is when chromosome 15 from the father is not passed on. so they child only gets the chromosome from the mother. so is it from the mother or father? it cant be both can it? the father's chromosome dissapears, so the mothers replaces it. it is so confusing. Remember that each parent contributes 1 allele, or copy of a chromosome. So in Prader Willi, the mother's allele is imprinted, or silenced and so you're depending on the father's allele for expression. But unfortunately, in PW you get deletion of the father's allele, which is why disease occurs. So yes- can occur in both males and females bc we're not talking about sex chromosomes here.
Is homologous recombination a type of mutation?
No. A mutation can change an allele into any other allele. Homologous recombination can only change an allele to the allele of the homologous chromosome.
What is it an example of when calico cats are mostly females because the allele for different covers is carried on the X chromosome so males are never multi colored?
sex-linked inheritance
How is a chromosome effeced by achondroplasia?
The only difference in the chromosome is the presence of the allele that results in an individual with acondroplastic dwarfism. The chromosome affects the structure of the organism, the allele affects the growth plates of the long bones resulting shortened limbs.
