Document Summary
Somatic cells are a regular type of body cell that is not involved in anyway in sexual in humans, a diploid cell has (46) chromosomes . Gametes are sex cells, so the egg and sperm . They are considered haploid because each gamete contains half the number of chromosomes (23) that an organism"s somatic cells will have. The gametes are the cells involved with inheritance because the dna contained in these are what is passed to the offspring: identify and apply chargaff"s rules. Chargaff"s rules state that dna from any cell of all organisms should have a 1:1 ratio (base. Pair rule ) of pyrimidine and purine bases and, more specifically, that the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine. Also that nucleotide base composition varies among species: distinguish between genotype and phenotype.
