Document Summary
The most common form of any property of an organism. Individuals that have some abnormal form of property. Heritable change in the dna of a gene. Coexistence of two or more reasonably common phenotypes. Gametes of only one type (female humans) all have x chromosome. Half the gametes are x and half y (male humans) Showing animal-like sexual dimorphism, with female plants bearing flowers containing only ovaries and male plants bearing flowers containing only anthers. Amass mutants affecting the biological property of interest. Cross the mutants to wild type to see if descendants show ratios of wild to mutant that are characteristic of single-gene inheritance. Deduce the functions of the gene at the molecular level. Deduce how the gene interacts with other genes to produce the property in question. *only steps 1 and 2 are covered in this chapter. A hereditary factor, called a gene, is necessary for producing pea colour.
