Quick Answer: What Was Thomas Hunt Morgan’s Main Contribution To Science?

What was the Thomas Hunt Morgan’s main contribution to science Brainly?

He created the first white-eyed male Drosophila. He showed that genes are linked in a series on chromosomes and are responsible for identifiable, hereditary traits. Morgan’s work played a key role in establishing the field of genetics. He received the Nobel Prize for Physiology or Medicine in 1933.

What was the purpose of Morgan’s experiment?

To test his hypothesis that the white-eyed trait was on the X chromosome, Morgan mated other specific groups of flies together and observed the offspring. Prior to doing so, Morgan predicted what the sex and eye color ratios of the offspring would be if his hypothesis were true.

What did Thomas Hunt Morgan’s experiment conclude?

Morgan’s conclusion— that the white-eye trait followed patterns of sex chromosome inheritance —was at once very specific and very grand. A few years prior to these test crosses, Mendelian ideas of inheritance had been enthusiastically discussed by many researchers in the context of new findings about chromosomes.

What laws violated the chromosomal theory of inheritance?

Q5: The chromosomal theory of inheritance violates which of the following laws? Explanation: The chromosomal theory of inheritance violated none of Mendel’s laws as the only difference was the genes being present in the chromosome, other than that the laws are as they were.
