I computed indicate H in the 160 microsatellite loci (described into the ), coating 35 linkage teams and you may an intercourse-averaged autosomal chart period of 1731 centiMorgan , whilst latter is probable an enthusiastic underestimate because of the number of indicators put . The 38–40 chromosomes usually used in birds have been included in at the least you to and maximally dos0 loci. Comprehend the electronic second matter to have facts about genotyping and you may mistake prices.

Right here, we report analyses according to imply multilocus heterozygosity (H; we.elizabeth. the newest small fraction away from genotyped loci which is heterozygous), replacement any forgotten philosophy during the certain locus on the suggest heterozygosity for it locus . Within dataset, H is nearly well correlated that have standard multilocus heterozygosity (correlation coefficient roentgen = 0.999) . As it could easily end up being interpreted as a possibility or good ratio, i here explore H as the a measure of heterozygosity.

(c) Matchmaking ranging from F and you can H, and you may term disequilibrium

We estimated the correlation between F and H (rF,H) and the slope of the regression of F on H (?F,H) using 1966 individuals that hatched in the years 1993–2006 and had all four grandparents genetically verified. We calculated the theoretically expected values using equations (1.4) and (1.5). We derived the theoretically expected identity disequilibrium g2 using equation (1.6), and estimated g2 from marker data using approximations derived by Hoffman et al. . These approximations allow for fast computation of g2, which is important for large datasets. We estimated a 95% CI by bootstrapping 10 000 times across individuals.

(d) Physical fitness

To stop difficulty arising from trade-offs one of physical fitness section , i used measures from exercise you to definitely feature more other lives values: lifespan (undertaking in the banding), lives amount of banded kiddies, lives number of mature young children for everybody individuals that hatched toward Mandarte Isle (that’s zero for all people that died ahead of reproduction effectively), and quantity of adult little ones lead during the lifetime of in your town hatched folks that lasted in order to adulthood merely (and thus decreasing the great number of zeroes present in another fitness methods).
