Help, I'm so confused! autosomal recessive, autosomal dominant, and s*x linked

Question

. For each of the following types of disorders, indicate which individuals (male and/or female) can be carriers for the diseased allele. What are the carriers’ genotypes?

Note: You may use a dash (–) to indicate the Y chromosome where appropriate (For example: A- instead of XAY).

Autosomal Dominant-

Autosomal Recessive

s*x-Linked Recessive

Answer 1

i think you will get more information in the Biology category

Answer 2

Autosomal Dominant - This means the gene is carried on one of your 22 pairs of somatic chromsomes (not s*x chromosomes) and that you only need one copy of the allele to show the trait.  So, no one can be a "carrier" because a carrier is someone who doesn't show the trait, but has an allele for it.  Since the trait is dominant, if you have the allele, then you show the phenotypic trait.

Autosomal Recessive - Again, on a somatic chromosome, but because it is recessive, you have to have two copies of the allele to show the phenotype.  So, both males and females can be carriers and their genotype would be Aa.

s*x-Linked Recessive - This means the gene is on a s*x chromosome and since they don't specify, it usually means on the X chromosome.  So, males cannot be carriers because they only have one X chromsome.  If they have the allele, they express it and show the phenotypic trait.  However, females can be carriers because they have two X chromosomes, one can carry the recessive allele and they still would not show the trait because their other X chromosome would carry the dominant/normal allele.  Their genotype would be X(A)X(a).
