LATEST VERSION. "Sexuality in plants is regulated by genetic, epigenetic and physiological mechanisms. The most specialized mechanism of sex determination is sex chromosomes." https://lnkd.in/g2Bsw9g View in LinkedIn

POROUS BORDER. "Unisexuality in flowering plants evolved from a hermaphrodite ancestor. Transition from hermaphrodite to unisexual flowers has occurred multiple times across the different lineages of the angiosperms." https://lnkd.in/g2Bsw9g View in LinkedIn

SEX DETERMINATION. "Epigenetic control and hormonal influence of sex determination were elucidated in both plants and animals." https://lnkd.in/g9AcjQt View in LinkedIn

MAJOR CHANGE. "Sex determination is a major switch in the evolutionary history of angiosperms. Sex chromosomes reinforce dioecy and increase genetic diversity." https://lnkd.in/g9AcjQt View in LinkedIn

PREVALENT. "Sexual dimorphism is prevalent among dioecious species." https://lnkd.in/ge7JD6J View in LinkedIn

DESPITE THE RISKS. "Separating sexual function between different individuals carries risks, especially for sedentary organisms. Nevertheless, many land plants have unisexual gametophytes or sporophytes." https://lnkd.in/griFcgZ View in LinkedIn

GENOME MODIFICATION. “The plague did write itself into human genomes: The descendants of plague-affected populations share certain changes in some immune genes.” https://lnkd.in/ggGWR4A View in LinkedIn

POSITIVE SELECTION. “Geneticists know that human populations evolve in the face of disease. Certain versions of our genes help us fight infections better than others, and people who carry those genes tend to have more children than those who don’t. So the beneficial genetic versions persist, while other versions tend to disappear as those carrying them die. This weeding-out of all but the best genes is called positive selection.” https://lnkd.in/gWy9UtF View in LinkedIn

THE OLD AND WEAK. “Scientists long believed that the Black Death killed indiscriminately. But DeWitte's previous research found the plague was like many sicknesses: It preferentially killed the very old and those already in poor health.” https://lnkd.in/ggGWR4A View in LinkedIn
