Question

of these two eggs.

7.   What is a genetic drift?

8.   What are the uses of fossils?

9.   What term did Mendel use for genes? Where are the genes located?

10.   What is the effect of DNA copying which is not perfectly accurate on the reproduction process?​

Answer 1

Answer:

7. variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce.

8. Fossils are also used to date sedimentary rocks. Some species with a broad distribution on Earth and a short-term life (Ammonites for instance) are great indicators to identify certain geological periods. Finally, fossils show us the long history of life and the past and current evolution processes on Earth.

9. The term Mendel used for genes are traits and these traits were later termed as genes. The genes are specific sequences of DNA that code for a particular protein. These genes are termed as the functional units of the DNA.

10. The DNA copying which is not perfectly accurate in the reproduction process results in variations in populations for the survival of species.
