The last time you saw the sisters pictured above, you considered how different protein molecules in their cells could lead to different traits. Now, you know that genes provide instructions for proteins that lead to traits. How could these sisters have ended up with different genes, leading to their different proteins and traits? Explain your ideas below. 60 words
These sisters could have ended up with different genes through a process called genetic recombination. During meiosis, the chromosomes from their parents can shuffle and exchange genetic material, leading to new combinations of genes in each sister. Additionally, mutations can occur spontaneously and be inherited, further contributing to differences in genes. These genetic differences can ultimately result in differences in protein molecules and subsequently, different traits.
