Meiosis – errors that occur Sexual reproduction is that the union of male and feminine gametes to create a fertilised egg or zygote. The ensuing offspring inherit one-half their traits from every parent. Consequently, they 're not genetically similar to either parent or siblings, except within the case of identical twins. As theorised by Mendel, adults are diploid, meaning as 2N, having 2 alleles offered to code for one attribute. The gametes should be haploid, signified by N, containing just
the cytoplasm of the cell divides in a process called cytokinesis, resulting in two separate and independent but identical diploid daughter cells. Meiosis occurs in two successive nuclear divisions: meiosis I and meiosis II. Meiosis I reduces the ploidy level from 2n to n (reduction) while Meiosis II divides the remaining set of chromosomes in a mitosis-like process (division). (8) The continuity of life is based on heritable information in the form of DNA and its transmission from one generation
1 Brief history of sugar beet The first references to the family of plants known as “Beta” can be found in Greek literature around 420BC. They were described as garden plants; dark and light varieties are mentioned. Sugar beet was first grown 2000 years ago originally for its leaves, which were probably the spinach or swiss chard of their day. Beet gradually spread throughout France and Spain, often in monasteries but also by peasant farmers. By the fifteenth century beet was grown all over Europe
Change is constant throughout all living things and that is particularly true when it comes to biology and in particular cell-division cycle. All organisms are constantly dividing and growing throughout their life time. The cell-division cycle in eukaryotes is a complex process that involves cyclins, cdks and multiple checkpoints that eventually lead to cell division. There are two different types of cell division which are Meiosis and Mitosis. Meiosis is the type of cell division which involves
