The genotype of the guinea pig that you would want to mate it with the black one is ww, which is also a white guinea pig, as all white guinea pigs must have the genotype ww as w is recessive to b. Also, make sure you know that the black guinea pig should have the genotype of bx, where x is either b or w.
So, if you mate the black guinea pig with the ww guinea pig (white), the offsprings will either be all black, or half black half white.
If the offsprings are all black, you can be sure that the black guinea pig (parent) will have the bb genotype. As each offspring must receive one gene from each parent, so if all the offsprings have black fur, they must have one b gene from the black guinea pig.
On the other hand, if the offsprings are half black half white, the genotype of the black guinea pig (parent) should be bw. This is because in order to have white offsprings, each parent must pass on a w gene so that the offspring would have genotype ww, white.
<h2>Gram Negative and Positive Bacteria</h2>
Explanation:
- The cell wall of <em>gram-positive bacteria is a peptidoglycan macromolecule </em>with joined adornment molecules, for example,<em> teichoic acids, teichuronic acids, polyphosphates, or sugars</em>
- <em>Gram-negative bacteria</em> organisms are not destroyed by specific cleansers which easily <em>kill Gram-positive bacteria </em>
- Surface displayed proteins on microbes play key role in <em>pathogenesis </em>as they elevate bacterial attachment to have tissues, acquisition of essential nutrients, evasion and suppression of<em> immune response and host cell entry</em>
The human activities in addition to natural factors that can alter the terrestrial ecosystem is deforestation.
<h3>The effects of deforestation on food web</h3>
Deforestation is a the clearing of trees in a large area of land which can be purposeful or by nature.
Human activities that leads to clearing of trees include the following:
- dam construction and infrastructure development.
One of the negative effects of deforestation on food web is the reduction in food availablity. This is so because of the loss of biodiversity that are source of food to man.
The human activities in addition to natural factors that can alter the terrestrial ecosystem is deforestation.
