Question

what effect did Sutton's discovery that chromosomes come in pairs have on his life?

Answer 1

Sutton studied over Brachestola magna

, a type of grasshopper.

He examined chromosomes, sperm production , cell division in B. Magna.

• His arguments were as follows :

1. Somatic cell contains one of the each of the parent chromosomes: he stated that the offspring receives random group of triad after parent triads are mixed. He also claims that , the individual chromosome retain its integrity when passed from parent to offspring.
2. Somatic cells have pairs of chromosomes
3. Each chromosomes code for a specific set of traits.
4. Chromosomes are predetermined in what trait they are coding for.
5. Each part of chromosomes will be different from another set of gene on a different chromosome.
6. He supported mendel’s theory that one parent’s triat will be expressed while the other parent triat will be hidden in an offspring.

Sutton argued on above mentioned points.

Sutton's theories explained the variance in and the combinations of traits in Mendel's work.  Later his argument was supported by Boveri, but his studies were independent from sutton but gave similar theories for role of chromosomes in inheritance.

Thankyou.
