ENDEL discovered that genes segregate, rather than blend during the process M of germ cell formation in heterozygotes. This makes sexual and asexual reproduction profoundly different in their genetic consequences. Asexual reproduction yields a progeny which, barring mutation, is genotypically uniform and identical with the mother. Sexual reproduction engenders genetic variability in the offspri...

The purpose of this clinical report is to provide pediatricians updated research on evidence-based sexual and reproductive health education conducted since the original clinical report on the subject was published by the American Academy of Pediatrics in 2001. Sexuality education is defined as teaching about human sexuality, including intimate relationships, human sexual anatomy, sexual reprodu...

The origin of sexual reproduction involved the evolution of zygotes from separate genomes and, like other social processes, should therefore be amenable to analysis using kin selection theory. I consider how kin structure affects sexual interactions in three contexts--the evolution of sexual reproduction, sex allocation and sexual conflict. Kin structure helps explain the even-handed replicatio...

Summary Ascospores generated during sexual reproduction are the primary inoculum for wheat scab fungus Fusarium graminearum . Purine metabolism is known to play important roles in fungal pathogens but its lifecycle stage‐specific regulation unclear. By characterizing genes involved purine de novo and salvage biosynthesis pathways, we showed that syntheses of inosine, adenosine guanosine monopho...
