Chapter 8.3. Meiosis. Types of Reproduction. Asexual reproduction Produce offspring with only ONE parent “babies” are identical to parent Sexual reproduction Produce offspring by meiosis and the joining of the sperm and egg “babies” are NOT identical to parents. Meiosis

DNA and Cell Reproduction

DNA and Cell Reproduction

DNA and Cell Reproduction. Chapters 10 and 8. Structure of DNA Deoxyribonucleic Acid. DNA is one of the two nucleic acids DNA RNA It is composed of repeating subunits (monomers) called NUCLEOTIDES. A nucleotide has three components – deoxyribose sugar A phosphate A nitrogenous base.

Meiosis

Meiosis

Meiosis. Chapter 11-4. The Basics. Genes are located on the chromosomes. Each organism must inherit one copy of every gene from both parents. Each organism has 2 complete sets of genes. Those two sets must be separated so that each gamete produced contains just one set of genes.

Meiosis

Meiosis

Meiosis. Meiosis. Cell division to form the gametes , sperm (male gamete) and egg (female gamete). Characteristic of eukaryotes only: not in prokaryotes. Normal cells are diploid : 2 copies of every gene.

Meiosis

Meiosis. What is Meiosis?. Meiosis produces daughter cells that have one half the number of chromosomes as the parent cell. 2N ® N. Meiosis enables organisms to reproduce sexually . Gametes (sperm and eggs) are haploid.
