I think the correct answer from the choices listed above is option A. When crossing-over takes place, chromosomes exchange corresponding segments of DNA. Corresponding genes on non-sister chromatids are exchanged at chiasmata. Hope this answers the question.
Answer:
Women can be carriers of the color blind gene and pass the mutation down the family line. If only the father is color blind, there is a 100% chance that his daughters will carry the gene, but they will not be color blind themselves. His sons will neither carry the gene nor be color blind.

Answer:
<h2>The virus is a bacteriophage that is reproducing the lysogenic cycle.</h2>
Explanation:
When bacteriophage infect the bacteria, it can enter one of two cycles i) lytic or ii) lysogenic cycle.
In lysogenic cycle, virus injects its genome into the bacterial chromosome, known as prophage and it replicates with bacrerial DNA. When conditions change, this prophage can remove itself from the bacterial DNA , and lysogenic cycle can change into lytic cycle.
Answer:Thomson's model showed an atom that had a positively charged medium, or space, with negatively charged electrons inside the medium. Soon after its proposal, the model was called a "plum pudding" model because the positive medium was like a pudding, with electrons, or plums, inside. Thomson developed what became known as the "plum pudding" model in 1904. Plum pudding is an English dessert similar to a blueberry muffin. In Thomson's plum pudding model of the atom, the electrons were embedded in a uniform sphere of positive charge like blueberries stuck into a muffin.
Hope this helps... Stay safe and have a great day!!! :D
