Due to independent assortment and crossing-over, the possible allelic combinations found in gametes by the meiotic division of this cell are B and D can be on one chromosome, while b and d can be on the other. Therefore, the correct answer is (B) BD, bD, Bd, and bd.
What is crossing-over?Crossing-over is a process that occurs during meiosis, the cell division process that produces gametes (sperm and egg cells) in sexually reproducing organisms. During crossing-over, homologous chromosomes exchange genetic material, resulting in the creation of new combinations of alleles.
What is the law of independent assortment?The law of independent assortment is a fundamental principle in genetics that describes how different genes are inherited independently. Gregor Mendel first proposed this principle.

Explain how the interaction of the Sun, the atmosphere, and the oceans produce winds.
Answer:
The heating of the Earth's surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents. The greater the pressure differences between a low-pressure area and a high-pressure area, the stronger the winds.

HELP WILL GIVE BRAINLIEST IF CORRECT: What effect do plants' roots
have on rock?
a. They hold it together
b. They weather it
c. They cause it to undergo chemical changes
d. They break it apart
Answer: C
Explanation: Reason why is because whenever the roots put pressure on the rock it cracks open and all the minerals release so it has to be going thru a chemical change because the roots receive the minerals from the rock or stone ...
Answer:
im guessing d but im not sure..,
Explanation:
When these roots grow, they exert pressure on the rock around them, causing the gaps to widen or even crack. Plant roots can also weather rock through chemical processes. When dead roots decompose, they release carbon dioxide; this is sometimes converted into carbonic acid, which chemically breaks down rock into soil.

With respect to climate change and natural selection acting upon a population of one species of frog in a tropical rain forest, mutations of DNA sequences of the frog genome that are inherited by offspring It is estimated by a wide body of scientists that in recent decades we have begun another mass extinction event on Earth. Amphibians in particular have been in decline, sometimes due to climate change, and they therefore provide a possible early sign of dramatic biodiversity change to come. With respect to climate change and natural selection acting upon a population of one species of frog in a tropical rain forest, mutations of DNA sequences of the frog genome that are inherited by offspring may have no effect at all, be beneficial, or be harmful. will primarily be harmful. will only speed the decline and extinction of the species. could either be beneficial or harmful.
Answer:
be beneficial.
Explanation:
Mutations of DNA sequences of the frog genome that are inherited by offspring will be beneficial for the frog because this mutation in the genetic makeup of frog provides resistance in this new environmental conditions. This mutation occurs due to the exposure of cell's DNA to the environmental factor which gives benefit to the organisms to survive different condition which can't tolerate by their parents so this mutation is beneficial for that offspring of frog.

The true breeding individual for all traits is RRYY.
What is True breeding ?A true-breeding organism, sometimes also called a purebred, is an organism that always passes down certain phenotypic traits to its offspring of many generations. This means that the parents are homozygous for every trait.
Since RRYY is homozygous for all traits, it will be a true breeding organism if crossed over with another RRYY organism. This is because all the off-springs produced from this cross will also be RRYY that is purebred.
