CHAPTER 11THE BASIC PRINCIPLES OF HEREDITY1.Heredity: transmission of genetic information from parent to offspring2.Genetics: the science of heredity3.Mendel’s work with peasa.Easy to grow and many varieties readily availableb.Easily distinguishable traitsc.Fast reproductiond.Controlled pollinations easy to conducti.Self-pollinate: male and female gametes from same flower4.Hybrid: offspring of two genetically dissimilar parentsa.Why hybrids mate with each other, they do not breed “true” b.Offspring of hybrids will show a mix of traits5.Genotype: genetic makeup of an organism6.Phenotype: physical appearance of an organisma.Ex. Brown fur7.Gene: unit of heredity (segment of DNA located on a chromosome)8.Alleles: alternative forms of a gene9.Locus (plural: loci): site of a gene on the chromosome10.A gamete has one set of chromosomes, the n number.
