On chromosome 1 of fruit flies, the gene for yellow body is 27.5 map units away from the gene for tan body, 43 map units away fr
Masja [62]

Answer:

the gene for yellow body and the gene for forked bristles

Explanation:

The two genes that will have the highest recombination frequency are the gene for yellow body and the gene for forked bristles.

<em>Gene recombination refers to the exchange of genetic materials between different gene-containing regions (loci) on the same chromosome or between two or more independent chromosomes. A linkage map shows the frequency of recombination between genes.</em>

Generally, on a linkage map, when two loci are close to one another on the same chromosome, the frequency of recombination of the genes would be less than that of two loci that are further apart. In other words, the closer the loci, the lower the frequency of gene recombination and vice versa.

<em>In this case, the distance between the genes for yellow body and tan body is 27.5 map units, yellow body and sable body is 43 map units, yellow body and forked bristles is 56.7 map units. </em><u><em>The genes for yellow and forked bristles are the furthest to each other with 66.7 map units and, as such, will have the highest recombination frequency. </em></u>

Halobacterium has a photosynthetic membrane that appears purple. its photosynthetic action spectrum is the inverse of the action
a_sh-v [17]

Yellow- Green Wavelength of light at peak absorption of 565nm.

Halobacterium is known to be a member of Archaea and they thrive in very salty environment such as Great Salt lake and Dead Sea. Halobacteria under the process of photosynthesis with chlorophyll and they make their ATP from the sunlight using bacteriorhodopsin and halorhodopsin as photosynthetic pigments.

However, photosensory pigements found in Halabacterium were:

1. photosystem 565 which is used to respond to yellow –green light in other for cell to find optimum conditions for ATP synthesis and photophosphorylation and they have peak absorbtion at 565nm.

2. Photosystem 370 nm appears to be responsible for the protective avoidance of blue/UV light.
