BIOL 1001 Lecture Notes - Lecture 4: Gene Pool, Product Rule, Allele
Document Summary
Not all organisms are diploid: bacteria are not, some vertebrates are tetraploid. Gene: unit, self contained, of genetic info. Allele: alternate form of a gene, produces genetic and phenotypic diversity. Locus: the place on a chromo where gene is found. Haploid: one copy of the chromosome. Diploid: a cell with two copies of chromosome, locus of gene is the same, alleles on chromosomes can be different, all somatic cells that have nucleus are diploid. Homozygous: for a gene the alleles the same. Heterozygous: for a gene the alleles are different. Genotype: can be applied to a pair of chromosomes, all chromosomes. Friday, january 20, 2017: describes the genes. Population: group of interbreeding in a speci c geographically close to each other, interbreeding: mixing of individuals breed, outside of family, inbreeding: breeding with close relatives. Gene pool: the important diversity is in the different alleles, allele pool is a better expression of diversity.
