Document Summary
Principle of segregation : genes occur in pairs in an individual. In the production of sex cells, the pair of genes separated. Gene: segment of dna that codes for protein. Punnett square: in genetics, a type of grid used to show the gametes of each parent and their possible offspring. Homozygote: having 2 copies of the same allele. Dominate allele: expressed phenotypically in both homozygote and heterozygote. Principles of independent: assortment: the segregation of one pair of gene does not influence the segregation of the other pair of genes. Round r wrinkle w tall t short s. Homologous chromosomes: pair of the chromosomes with the same sequence of genes. Centromere- constricted portion of the chromosome that hold two chromatids together. Interphase: genes are active , chromosomes duplicate/ replication. Mitosis: prophase, metaphase chromosomes align independently from one another, anaphase centromeres, telophase. Two daughter cells are produced, both with the diploid chromosome number: diploid- full complement of chromosomes, 2.
