- <em><u>Thomas Hunt Morgan work with the fruit fly showed that genes are linked in a series on chromosomes and are responsible for identifiable, hereditary traits. </u></em>He was the first to identify that genes are linked to the same chromosome.
- <em><u>According to his hypothesis he stated that genes that are linked are arranged linearly on a chromosome, while those genes with low combination frequencies must be closer together and thus difficult to separate</u></em>.
- When a gene contains two similar alleles that is, either two dominant alleles or two recessive alleles then it is called homozygous dominant and homozygous recessive respectively. White eyes of a fruit fly is an example of homozygous recessive
