The fetal adrenal cortex produces dehydroepiandrosterone sulfate DHEA-S used by the placenta to produce estrogens. Indeed, many genes may serve as potential targets for sex determination in plants, given that male or female sterility can evolve in various ways [86].

Sex portal. However, other homologous genes, Cyp19a1a and Cyp19a1bSox8a and Sox8b were placed in different modules, suggesting a functional difference of these duplicate genes. Menarche Menstruation Follicular phase Ovulation Luteal phase.

A sufficient amount of any androgen can cause external masculinization. The two missing sequences were inferred manually from the genome assembly: one, FGF9 , was identified by comparison with orthologous sequences of other species, and the other, GSDF , by aligning an L.

Even though the outcome of sex determination—whether an individual produces relatively few large ova or many small sperm—is strongly conserved, a bewildering number of underlying mechanisms can trigger development as either a male or female [3] , [4].

Submit Feedback. Elger, W. Cell-autonomous sex determination can result in the formation of gynandromorphs—individuals that contain both male and female characteristics, found in birds and many insects, including butterflies and beetles.
