Basic Introduction to Heredity notes

Introduction to Heredity:

• Offspring inherit traits passed down from the biological parents.

• Some traits dominate other traits.

• There are two 'types' of alleles: recessive and dominate alleles. An allele is a specific version of a gene.

• (Gregor Mendel - monk- father of classical genetics. Cross bred plants to see what traits are handed down. Before the understanding of DNA. 1850's.)

• The locus on a chromosome = The location of a gene on a chromosome.

• The locus/ location of a gene on a chromosome i.e. from the mother will match the locus of the gene on the  father's chromosome.

• Ways a gene is expressed…
