Agene that has two alleles, a and a, is located on the same chromosome as a second gene that also has two alleles, b and b. suppose a diploid individual has alleles ab on one copy of this chromosome and alleles ab on the other copy of this chromosome. for this individual, select the pair of recombinant genotypes that could result if crossing over occurs between these two chromosomes.

The correct answer to the question: For this individual, select the pair of recombinant genotypes that could result if crossing over occurs between these two chromosomes, would be, 3. Ab and aB.

Explanation:

During meiosis, the copy and distribution of genetic information present in genes, and which happens when chromosomes are divided and then crossed over, is a pretty unique one.

Essentially, genetic recombination happens when genes cross over and combine with genes present close to them. This process does not always happen and it is the reason why we say that some gametes are parental, instead of recombinant; because the genes in the chromosomes, especially depending on factors like distance between them, do not combine.

In this particular case, given the way that genes will cross over and knowing how recombination works, we could say that the possible genotypical recombinants for AB on chromosome 1 and ab on chromosome 2 would be the ones offered in option 3.

Answer from: Quest

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

On a backpacking trip, kenny hikes all day at a steady pace, covering 30 kilometers and burning 4000 calories. at the school track, janelle runs the 100-meter sprint in 13.5 seconds, burning 10 calories. afterward, janelle’s leg muscles are aching and she is breathing hard, while kenny maintains normal breathing all day, even though he burns 400 times more calories than janelle. which two statements offer the best explanation for this phenomenon? a. if the aerobic pathway—cellular respiration—cannot meet the energy demand, then the anaerobic pathway—lactic acid fermentation—starts up, resulting in lactic acid buildup and "oxygen debt." b. aerobic cellular respiration produces more energy, but its use is limited because of lactic acid buildup in the muscles and the resulting "oxygen debt." c. after about 90 seconds of intense exercise, the muscles become depleted of oxygen, and anaerobic respiration can no longer function to produce atp, resulting in "oxygen debt." d. the rate of energy demand determines how the muscles will obtain energy, either from cellular respiration or from lactic acid fermentation if not enough oxygen is present.
