   Yes it does, as long as it's a *recessive* gene and can be passed on by   
   heterosexual individuals who carry the gene.  Kinship selection is not   
   limited to helping one's own offspring survive, but also includes helping   
   other young kin survive.   
      
   Your brother or sister most likely has 50% of your genes.   
   Your niece or nephew most likely has 25% of your genes.   
      
   Now if a couple are both carriers of a recessive gene then the odds are   
   1/4 that a given son or daughter of theirs will have 2 copies, 2/4 that   
   s/he will be a carrier, and 1/4 that s/he will have 0 copies.   
      
   OK, what about survival?  In species with "r-strategy" reproduction (have   
   tons of offspring, at least some will keep themselves alive), this is   
   irrelevant.  In species with "K-strategy" reproduction (have a few   
   offspring and try to keep all of them alive), this is very relevant.  So,   
   in a "K-strategy" species:   
      
   - Who's more likely to survive and pass on genes?  S/he who has only   
   parental care?  Or s/he who has Mom and Dad *and* an aunt or uncle or two   
   caring for her?   
      
   - Who's most likely to be a carrier for some recessive gene which makes   
   adults nonreproductive and healthy?  S/he who has carrier parents and   
   nonreproductive aunts and uncles, or s/he who doesn't?   
      
   Thus, having aunts and uncles who don't reproduce and spend their "care   
   for related kin" instincts on nieces and nephews instead is a survival   
   trait.  In other words, one's being likely a *carrier* of a recessive   
   gene for homosexuality would increase reproductive fitness because it   
   increases the odds of one's surviving childhood living long enough to   
   reproduce.
