Genetics - Inheritance and Selection

Genetics - Inheritance and selection (part 1)

Genotype and Phenotype

• Genotype- genetic makeup of  organism
•  Sets limits within which characteristics of an induvisual can vary
•  Limits are set by env. Factors .: can change the potential characteristic.
•  Change to genotype due to change in DNA – MUTATION. This is inherited in the form of gametes.

•  Phenotype- observable characteristics of an organism.
•  Results from interaction between genotype and environment – affects appearance
• Change in phenotype doesn’t change genotype – MODIFICATION

Genes and Alleles:

•  Genes – section of DNA(Sequence of nucleotide bases) determines single characteristic by coding for…
