Y-linked Mendelian inheritance of giant and dwarf male morphs in shell-brooding cichlids.
Behavioural variation among conspecifics is typically contingent on individual state or environmental conditions. Sex-specific genetic polymorphisms are enigmatic because they lack conditionality, and genes causing adaptive trait variation in one sex may reduce Darwinian fitness in the other. One way to avoid such genetic antagonism is to control sex-specific traits by inheritance via sex chrom...
متن کاملMale and female shell-brooding cichlids prefer different shell characteristics
http://dx.doi.org/10.1016/j.anbehav.2014.10.004 0003-3472/© 2014 The Association for the Study of A In resource defence polygyny, where males defend resources that females use for reproduction, the resource characteristics preferred by the two sexes are expected to match. We tested this expectation by comparing the shell characteristics preferred by males and females in the shell-brooding cichl...
متن کاملAlternative reproductive tactics in snail shell-brooding cichlids diverge in energy reserve allocation
Life history theory predicts that the amount of resources allocated to reproduction should maximize an individual's lifetime reproductive success. So far, resource allocation in reproduction has been studied mainly in females. Intraspecific variation of endogenous energy storage and utilization patterns of males has received little attention, although these patterns may vary greatly between ind...

متن کاملتوارث مندلی (mendelian inheritance)
بیماری های مندلی بیماری هایی هستند که ناشی از اثرات یک ژن بر فنوتیپ فرد می باشند. انتقال آنها از نسلی به نسل دیگر همانند الگوهایی است که مندل توضیح داد. اگر ژن بیماری ها بر روی کروموزوم های جسمی (اتوزوم) قرار داشته باشد این توارث را جسمی (autosomal) و اگر بر روی کروموزوم های جنسی قرار داشته باشد آن را توارث وابسته به جنس (sex-likned) می نامند. طرح توارث بیماری ها از طریق انتقال صفات در خانواده ...
