Chromosomes and Human Genetics

Chromosomes and Human Genetics. Chapter 12. Chromosomes & Cancer . Some genes on chromosomes control cell growth and division If something affects chromosome structure at or near these loci, cell division may spiral out of control This can lead to cancer. Philadelphia Chromosome.

What are chromosomes?

What are chromosomes?. Genetic materials found inside the nucleus of a cell Made up of DNA & protein Appear as very thin & thread-like structures called Chromatins Each cell in each type of organism has a definite number of chromosomes

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. 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.
