Fitness outcomes off polymorphic inversions regarding zebra finch genome

Inversion polymorphisms constitute a keen evolutionary secret: they want to raise embryo death when you look at the heterokaryotypic people but nevertheless they was common in some taxa. Some insect species enjoys advanced elements to attenuate the price of embryo mortality but humans have not. For the wild birds, reveal studies was destroyed even when intraspecific inversion polymorphisms is actually considered as the prominent. Inside Australian zebra finches (Taeniopygia guttata), several polymorphic inversions are understood cytogenetically so we set out to choose both of these and you will potentially extra inversions using genomic products and you can analysis their consequences on embryo death and other physical fitness-related and you can morphological characteristics.

Show

Playing with entire-genome SNP studies, i processed 948 nuts zebra finches to have polymorphic inversions and explain four large (12–63 Mb) intraspecific inversion polymorphisms having allele wavelengths alongside fifty %. Using additional data out-of 5229 birds and 9764 eggs regarding nuts and you can about three captive zebra finch populations, i reveal that only the premier inversions increase embryo death inside the heterokaryotypic people, having surprisingly quick impact products. I decide to try to possess a beneficial heterozygote advantage over most other physical fitness components however, find no evidence to possess heterosis the of the inversions. Yet ,, we find strong ingredient outcomes on several morphological faculties.

Results

New process who has transmitted new derived inversion haplotypes so you’re able to such higher allele frequencies stays evasive. (περισσότερα…)
