<span>Parents can pass on chromosomes to their children that are different than their own when the new gene combinations are created by crossing over. The exchange of genetic material between homologous chromosomes is known as crossing over which occurs in meiosis. When homologous chromosomes pair up and exchange different segments of the genetic material. As the result, a new combination of genes will be formed. If there was not crossing over, all genes on a chromosome would be inherited together.</span>
All of these components are reservoirs of carbon. The cycle is usually discussed as four main reservoirs of carbon interconnected by pathways of exchange. The reservoirs are the atmosphere, terrestrial biosphere (usually includes freshwater systems), oceans, and sediments (includes fossil fuels).
Answer:
Same age stars is a mark of Galaxy formed by collapse
Explanation:
Before a galaxy can be formed, the materials that help in building the galaxy rotate at a speed, it's the come together and collapse by it self due to it's gravitational pull. When it's collapse globular are formed and it's away from it's nucleus. The clusters this give rise Halo stars which are stars of the same age.
Answer:
c. All eight possible phenotypes could occur, but a greater proportion of the offspring would have the parental phenotypes
Explanation:
When genes are linked they do not assort independently. Instead, the alleles on the parental chromosome will have a tendency to migrate together to the same pole of the cell. To produce gametes with genotypes different than the parentals crossing over must happen between the genes of homologous chromosomes during meiosis. However, recombination is a rare event, so the recombinant gametes will be less frequent than the parentals (those that arise when no recombination occurs between genes) and for that reason a greater proportion of the offspring will have parental phenotypes.
