MEIOSIS  In sexually reproducing organisms, gametes (sex cells) are produced by a special type of cell division called meiosis.  Meiosis results in gametes.

Mitosis vs. Meiosis. What is the difference Mitosis is asexual reproduction. Does not produce a new organism. Mitosis is asexual reproduction. Does not.

Mitosis/Meiosis How do your cells divide?. A few words before we start….. Haploid:n one set of chromosomes Diploid: 2n two sets of chromosomes.

Sexual and Asexual reproduction. A type of reproduction that involves only one parent and produces offspring that are genetically identical to the parent.

Cellular Reproduction

1 Reproduction. 2 Production of new individuals is a fundamental characteristic of a living species. Genetic information is passed on from parental generation.

6.1 Chromosomes and Meiosis KEY CONCEPT Gametes have half the number of chromosomes that body cells have.

Sexual Reproduction and Genetics

Year 10, Pathway C  DNA Replicates in preparation for cell division  Each new cell needs the same DNA.

DNA and Cell Cycle. DNA and Chromosomes  DNA is in the nucleus of every living thing.  A Chromosome is coiled DNA.  Humans have 46 chromosomes.

Meiosis Cell division – ‘ reduction division’ Production of sex cells – gametes.

REPRODUCTION AND CONTINUITY OF LIFE

Reproduction Cell division MitosisMeiosis requires

Mitosis asexual reproduction production of genetically identical offspring from one parent Gives rise to genetically identical cells in which the chromosome number is maintained Growth, repair of damaged tissues, replacement of worn out cells and asexual reproduction

Meiosis Reduction division chromosome number is halved from diploid to haploid Diploid 46 chromosomes Haploid 23 chromosomes Results in Gametes. Sexual reproduction Haploid nuclei to form a diploid zygote(embryo/new born cell) Genetically dissimilar offspring
