What is the pattern of sex linked inheritance?
In humans sex linked traits are passed on the X chromosome. (For the purpose of this discussion the trait being passed is recessive.) This means that a male parent cannot pass the characteristic on to his male offspring, but he can pass the trait on to his female offspring. The female parent can pass the trait on to any of her offspring. Both parents must carry the allele for the sex-linked trait (and pass it on) in order for a female child to have the characteristic. Male children that get the trait from their mother will have the trait no matter what the genetics of the father. If the female parent is heterozygous for the trait 50% of her male children will have the characteristic no matter the father's genetics for that trait. Assuming that the characteristic is not lethal and both parents are "carriers" (keep in mind that the father displays the trait and a heterozygous mother will not)... 50% of the sons will have the trait, 50% of the sons will not have the trait, 50% of the daughters will be homozygous for the trait and 50% will by heterozygous "carriers".
How do you recognize a pedigree for an x-linked recessive allele in human beings?
For a recessive sex-linked trait to manifest in women it would have to be in double dose (XaXa) while for men in single dose (XaY). Women carriers would have one of each but would not be affected (XAXa). Knowing this it's quite easy to spot pedigrees where this kind of inheritance occures.Heterozygote mothers (gene carrier) can have sons that are affected (50% chance);Affected mothers have only affected sons (100%);No first generation daughter of an heterozygote mother will be affected but there is a 50% chance that she is a carrier;Affected fathers with normal mothers will have zero sons that are affected but all their daughters will be carriers;
If your husband has a lot brothers will you birth a lot of sons?
No. The gender of the baby is always a 50/50 chance. Females have two X chromosomes, while males have one X and one Y. If the father gives the X chromosome, then the baby will be a girl (XX) but if the father gives a Y chromosome then the baby is a boy (XY). Whether he gives an X or a Y is completely random.
