Two genes, A and B, are located 30 map units apart. A mating between an individual homozygous dominant for both traits and one h
Westkost [7]

Answer:

35%

Explanation:

If two genes are 30 map units apart, 30% of the produced gametes will be recombinant.

A mating between an individual homozygous dominant for both traits (AB/AB) and one homozygous recessive for both traits (ab/ab) is conducted.

The F1 will be heterozygous for both genes: AB/ab.

The F1 progeny is then test-crossed to a homozygous recessive individual:

<h3>AB/ab X ab/ab</h3>

<u>The possible offspring will be:</u>

  • Parental (70%): AB/ab and ab/ab
  • Recombinant (30%): Ab/ab and aB/ab

Since 30% of all the gametes produced by the F1 individual will be recombinant, 70% will be parental. As there are two types of parental gametes, each of them will have a frequency of 35%.

<u>The offspring that will have a dominant phenotype for both traits has the genotype AB/ab with a proportion of 35%.</u>

When microbial action during decomposition in aquatic ecosystems removes too much oxygen, the body of water experiences .
pashok25 [27]

The body of water experiences eutrophication.  

The process of eutrophication takes place primarily in ecosystems with gradual changing waters, mainly in deep lakes. In the depths of the lake, where deposition of dead algae takes place, the aerobic bacteria, which feeds on them proliferate that in turn consumes more amount of oxygen.  

Though in the absence of enough circulation of water that is usually found in the case of deep lakes, the bottom of the lake is poorly oxygenated and the bacteria eventually deplete the oxygen found in the deep layers of water. Thus, they can no longer degrade all the dead organic matter and gets accumulated in the sediments. The lake is now considered to be aging.
