Figure 2 highlights the possible pathways for the evolution of separate sexes from a hermaphrodite ancestor name of male sex cell in animals in Seattle illustrates their relation to sex chromosome evolution. Trends Genet 28 : — The answer begins in the late s, when insect gonad cells, whose large chromosomes are easy to view through a microscope, were the specimen of choice for investigating the cellular basis of heredity.
Thus, the Y chromosome can be a stable and important component of the genome in many species, and may even prevent turnover of sex-determining mechanisms see below. What scientists find puzzling is that most of them still use a system of two sexes — in their case plus and minus rather than male and female.
What is the name of plants that grow from a single cell? Gamete a male or female sex cell ie the egg or the sperm. What is the male sex cell called? If a sperm cell containing an X chromosome fertilizes an egg, the resulting zygote will be XX or female. Because plants are only multicellular, a plant growing from a single cell would be a clone.

Campbell NA Biology. Open in a separate window. As an analogy, one can imagine the genome as an key piano in each cell. Female gametes are made by female reproductive structures. In , an international panel concluded there are 22 human autosomes, and they should be numbered in a descending fashion, from longest to shortest.
