Document Summary
Lecture 6 sex, reproductive systems and evolution. Hermaphrodite: individuals that perform both as females and males. You mate with yourself -- not cloning! because gametes are involved. Water fleas: different reproductive systems occur in different environment. In cold water, more energy are used to metabolize heat than reproduce. Easier to move around and encounter a mate. Many perennial plants (e. g. water hyacinth) reproduce through both sexual and clonal reproduction. Potential for sex (but there is only one form in the population) The plants are getting cues by touching the roots to the soil that it is the time to flower. Time and energy to find and attract mates. You will expose yourself when look for mates. If it reproduces asexually, you don"t need males. Asexually -- transmit all its genes to the next generation. This is the big question known as the paradox of sex".
