to the ameboid members of the phylum Chrysophyta. Sarcodines may reproduce asexually by cell division‚ often without breakdown of the nuclear envelope that is typical in mitosis‚ or sexually by meiosis and the production of haploid gametes‚ followed by fusion of gametes and the formation of zygotes.

For a plant that is Pp‚ two gametes are produced: P and p. For a plant that is PpTt‚ four gametes are produced: PT‚ pT‚ Pt‚ and pt. For a plant that is PpTtYy‚ eight gametes are ultimately produced: PTY‚ PTy‚ Pty‚ pTy‚ ptY‚ PtY‚ pTY‚ and pty. 4.)

Mendel’s work were published in 1866 as "Experiments with Plant Hybrids" in the society’s journal. Mendel’s Law of Segregation stated that the members of a pair of homologous chromosomes segregate during meiosis and is distributed to different gametes. This hypothesis can be divided into four main ideas. The first idea is that alternative versions of genes account for variations in inherited characters. Different alleles will create different variations in inherited characters. The second idea

The seven processes of life The seven processes of life are the key to all living organisms: these processes consist of nutrition‚ growth‚ movement‚ respiration‚ reproduction‚ sensitivity and excretion. Although‚ they may be achieved in different ways depending on the organism. These processes happen with in both plants and animals; in each organ‚ cell and organelle. All these processes are interlinked and have a chain effect upon one another. Without one of them the others aren’t possible.
