The best explanation for this is 2.When looking atypBT and ASPM, some individuals counted as parental are actually double recombinant
The sum of the two intervening distances is larger than the distance between the outside genes DBT and ASPM (less than 33 map units). Why? because not all of the recombination events (double crossovers) are taken into account by the calculated distance between DBT and ASPM.
Thus, the map distance would have been greater if there were more double recombinants. Again, the map distance would decrease if the number of parents was higher. The map distance is lower here than anticipated. This indicates that the number of parents is higher than it ought to be.
Therefore, the best choice is 2.

(complete question)
You are measuring recombination between three genes: DBT, MEN2 and ASPM. The recombination fraction between the DBT and MFN2 is 15% and between MFN2 and ASPM is 18%: However, the recombination fraction between DBT and ASPM is slightly smaller than, but close to, 33%. What is the best explanation for this?
- One of these genes may be on different chromosomes than the other two but this fact is masked because of double recombinants
- When looking atypBT and ASPM, some individuals counted as parental are actually double recombinant
- When looking at DBT and ASPM, some individuals counted as double recombinants are actually parental
- DBT and ASPM actually assort independently
The answer is A, the division of cells into two identical cells.

Answer:
An acid is a substance that donates hydrogen ions. ... Now there are more hydrogen ions than hydroxide ions in the solution. This kind of solution is acidic
The correct statements are I, III and IV.
An angiosperm refers to a plant, which exhibits flowers and generates seeds enveloped within a carpel. The angiosperms include a large group of herbaceous plants, grasses, shrubs, and the majority of trees. While gymnosperms refer to the plants that exhibit seeds but not safeguarded by any kind of fruit or ovary. It includes the cycads, gingko, and conifers.
Both the angiosperm (sunflower) and gymnosperm (gingko) are seed-bearing plants. However, the seeds of a sunflower are safeguarded by a flower or fruit, while for the gingko, there is no mechanism like that, i.e, there is not any kind of protection. Additionally, sunflower exhibit phenomenon of double fertilization, which is not witnessed in the case of gingko.
