Therefore there is 50% chance of a male child being born and a 50% chance of, This mechanism of sex determination is called, In grasshoppers and some other insects, the male has only one sex chromosome (XO) whereas the, female has two homomorphic (of same size and shape) sex chromosomes (XX). Female, therefore, produces same type of all gametes (ova or eggs). A gene is a hereditary unit, a segment of DNA, having specific sequence of nucleotides that determines its specific biological function.It can, maintain constancy from generation to generation but at times may also undergo sudden. He supported his argument by pointing out that farmers and breeders have developed many varieties of animals and plants through artificial selection. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. Paleontology (study of fossils) 5. Because a great amount of data supports the idea of biological evolution through natural selection, and because no scientific evidence has yet been found to prove this idea false, this idea is considered a scientific theory. Sex determination is sometimes regulated by environmental factors . The nitrogenous base of each nucleotide is attached to the sugar molecule and.
