Answer:
a Anaphase I
b Metaphase I
c Telophase I
d Anaphase II
e Prophase I
f Telophase II
Explanation:
Prophase I begins after the DNA has been duplicated, as shown in picture e. The chromosomes are condensed, and also visible, which is apparent in picture e.
The next stage is called Metaphase I, in which the pairs of homologous chromosomes align at The the centre of the cell and the spindle fibres attach, as shown in picture b.
The pairs of chromosomes are pulled apart to opposite poles of the cell by the spindle fibres., as shown in picture a. This stage is called Anaphase I.
Then, a process called Telophase I occurs, when the cell divides into two daughter cells. One of these cells is shown in picture c.
Picture d shows the stage Anaphase II, where the spindle has attached and the chromatids are pulled to the opposite poles of the cell.
The final picture left is picture f, which shows the daughter cell at the end of meiosis II, where the nuclear envelope is reforming, as in telophase II.
Answer:
White eyes are lethal in male Drosophila was the hypothesis of Thomas hunt which was valid. Hence the answer is option B.
Explanation:
Thomas hunt Morgan was a famous American biologist. He was more famous because of his experiment on drosophila which contributed most of things about the lifestyle and health science in much of the findings about those insects.
He was also awarded by the Nobel prize for his works which was related to medicine in 1933. He has also contributed many knowledge about the chromosome and heredity. he is finding is very helpful nowadays for the scientist and other biologist.
