The majority of butterflies and moths also have a ZW sex-determination system. Tim rejects Jenny, who learns about Marina's other lover; Bette struggles with her fears about parenthood, while Dana runs from her fears and from Lara; Kit is stung when her son doesn't show up for their meeting. Sean Holden who are investigating the death of Jenny Schecter. Other examples demonstrate that it is the preference of females that drive sexual dimorphism, such as in the case of the stalk-eyed fly. In mammals, the fertilized embryo instead develops within the female, receiving nutrition directly from its mother. In both XY and ZW sex determination systems, the sex chromosome carrying the critical factors is often significantly smaller, carrying little more than the genes necessary for triggering the development of a given sex. This may be associated with the cost of producing egg cells, which requires more nutrition than producing sperm—larger females are able to produce more eggs.

Part 2 Bette Porter and Tina Kennard have been a couple for seven years and want to start a family. Humans and other mammals have an XY sex-determination system: Because of their motility, animal sexual behavior can involve coercive sex. In female mammals the vagina connects with the uterus , an organ which directly supports the development of a fertilized embryo within a process called gestation. Genetic Like humans and other mammals, the common fruit fly has an XY sex-determination system. Yeast with the same mating type will not fuse with each other to form diploid cells, only with yeast carrying the other mating type. These gametes combine to form embryos which develop into a new organism. Conversely, there are also species in which there is no sexual specialization, and the same individuals both contain masculine and feminine reproductive organs, and they are called hermaphrodites. This is called X0 sex-determination —the 0 indicates the absence of the sex chromosome. Many plants, including conifers and grasses, produce lightweight pollen which is carried by wind to neighboring plants. Sexual dimorphisms in animals are often associated with sexual selection — the competition between individuals of one sex to mate with the opposite sex. In pines and other conifers the sex organs are conifer cones and have male and female forms. Some plant species also exhibit dimorphism in which the females are significantly larger than the males, such as in the moss Dicranum [46] and the liverwort Sphaerocarpos. Isogamy and Anisogamy The life cycle of sexually reproducing organisms cycles through haploid and diploid stages Sexual reproduction in eukaryotes is a process whereby organisms form offspring that combine genetic traits from both parents. While the show is seen as fulfilling lesbians' "obvious and modest representational need" [41] or even the "ferocious desire not only to be seen in some literal sense In field crickets , for example, insects with a single X chromosome develop as male, while those with two develop as female. Each video showed the interrogation of one character with a new video being released each Monday after the final episode via the Showtime website. Jo on " Facts of Life "? Bacteria, for instance, reproduce asexually, but undergo a process by which a part of the genetic material of an individual donor is transferred to another recipient. Sex-determination system Sex helps the spread of advantageous traits through recombination. The most basic sexual system is one in which all organisms are hermaphrodites , producing both male and female gametes—[ citation needed ] this is true of some animals e. They are specialized for motility, seeking out an egg cell and fusing with it in a process called fertilization. Send us Feedback Get Help 1. Typically, prior to an asexual division, a cell duplicates its genetic information content, and then divides. The defining characteristic of sexual reproduction in eukaryotes is the difference between the gametes and the binary nature of fertilization.

    Some bacteria use conjugation to transfer genetic material between cells; while not the same as sexual reproduction, this also results in the mixture of genetic traits.

    In some of these cases, the fusion is asymmetric, and the cell which donates only a nucleus and not accompanying cellular material could arguably be considered "male". This double-chromosome stage is called " diploid ", while the single-chromosome stage is " haploid ".
