Title: Mitosis and Meiosis Abstract: There are two types of nuclear division‚ mitosis and meiosis. Mitosis is usually used for the growth and replacement of somotaic cells‚ while meiosis produces the gametes or spores used in an organism’s reproduction. Hypothesis: Mitosis occurs in whitefish blastula and onion root tip‚ and it is easily observable. Meiosis and crossing over occurs in the production of gametes and spores. Materials: This lab required prepared slides of whitefish blastula

Lab 8: Mitosis‚ Meiosis and the Cell Cycle . header Purpose: This activity is designed to familiarize you with the phases of mitosis and meiosis and compare these processes in a comparison chart. This activity will be three parts. For parts I and II‚ please scan your labeled work. Preparation: There is no preparation or materials needed for this activity. You will simply need access to a scanner to submit your work. Procedure Part 1: For this portion of the laboratory‚ please sketch a cell

That means that the old cells died and the new ones took their place. • Reproduction: This is a result of mitosis or meiosis‚ depending on the type of reproduction. There are two types of reproduction. The first type is asexual reproduction‚ and this is when there is only one parent. This results from normal cell division. This occurs in bacteria‚ protests‚ fungi‚ some

Genetics Paper Each human in the world is created both separate and unique. Although members of a family may possess common traits‚ each member has their own individuality. Genetics allows for a creation of a unique individual. Chromosomes‚ meiosis‚ and fertilization are essential parts of genetics vital to the development of a distinct organism. The effect of each allows for a world in which no human is equal. To begin‚ chromosomes in genetics plays a key role in individuality. In genetics

P1: Explain how sperm and ova are formed by producing an annotated diagram of meiosis and discussing what happens in ogenesis and spermatogenesis In the male‚ meiosis precedes sex cell differentiation. A single spermatogonium enters the first meiotic division as a primary spermatocyte. This division produces two secondary spermatocytes‚ each of which divides to form two haploid spermatids. Each spermatid then differentiates (by a process called spermiogenesis) into a spermatozoon by the elaboration

Haploid (N) is half of the diploid num-ber. In interphase‚ chromosomes are replicated and align in homologous pairs. Each pair contains a maternal and paternal homologue inherited from the previous genera-tion. An important consequence of meiosis is that the genomes are mixed and
