One hypothesis that explains the result is : A) Two genes are involved with 12:3:1 epistasis, such that A_B_ and A_bb are black, aaB_ is brown,and aabb is green.
Explanation:
- This is a case of Dominant Epistasis.
- When two genes are involved and presence of dominant allele of one gene masks the effect of either allele of the second gene then the epistasis is termed as dominant epistasis.
- In the given case black :brown: green ratio is approximately equal to 12:3:1.
- Here presence of a dominant A allele that is responsible for the black colour masks the effect of either allele of B. Therefore A_B_ and A_bb produces black beetles
- Again , absence of dominant A allows B to express itself and Brown beetles are produced thus aaB_ is brown.
- When both the genes are present as recessive alleles, neither brown nor black colour is expressed and the beetles are green.Thus, aabb are green.
Answer:
- <u>Similarities And Differences:</u>
If a topic, law or scientific research shares the same origin of study, similar to another topic or term, then they will be compared and further analyzed by the team of scientists and research workers in order to have some conclusions and results.
Explanation:
- As there are many scientific research and analyses which is been carried out in order to analyze the different elements in the process of comparison between any two subjects and terms.
- <em>There are various subjects and topics of research work. Many of the scientific research work are in parallel to each other as they are somehow compared by other scientists and research workers.</em>
the believe they move inside the membrane which is creating a gradient
<span>Because 3,500 calories equals about 1 pound (0.45 kilogram) of fat, you need to burn 3,500 calories more than you take in to lose 1 pound. So, in general, if you cut 500 calories from your typical diet each day, you'd lose about 1 pound a week (500 calories x 7 days = 3,500 calories).
