Not sure if this is the format you want it in but
F1:
Genotype: RWHh, RWHh, RWHh, RWHh
Phenotype: basically all of them would have the roan coat and they would be hornless
F2:
Genotype: WWHH, RWHh, RRHh, RWhh
Phenotype: one will have a white coat and hornless, roan coat and hornless, red coat and hornless, roan coat and horned
Hope this somewhat helped
Hello,
Please find below a short summary on the subject you have been assigned. This will help you in completing your project and also give you an overview on the current research on this subject.
Food additives are chemical substances added to food in order to either maintain or improve its physical characteristics such as taste, texture, appearance and even freshness.
The long term effects that these substances have on the human body are still largely unstudied. According to the hypothesis called "chemical obesogen", these synthetic compounds are contributing factors to the global obesity epidemic.
Although evidence-based scientific research is still lacking, the support for this hypothesis is growing as many of these additives have been found to disturb the body's endocrine functions.
Furthermore, artificial preservatives used today may increase the risk of inflammatory bowel disease. This has been shown by a study on mice in which the food additives known as emulsifiers (carboxymethylcellulose and polysorbate-80) have been shown to affect the animal's health.
Due to these chemicals, the mice not only became obese but also developed metabolic problems such as glucose intolerance. It seems that these chemicals affect the gut bacteria population in a negative way, as mice lacking gut bacteria did not become ill.
The mice study was followed by another study in which the human simulated through a series of flasks. Under the influence of the emulsifiers arboxymethylcellulose (E566 on EU labels) and polysorbate-80 (E433), the levels of bacterial protein called flagellin increased. This protein is known to cause inflammation at high concentrations. The next step in the study will be the first human trials.
Due to the long road our food takes from the farm to our table more extensive research is required. There are thousands of compounds that change the biochemical properties of the plants and animals that constitute our diet. The effects of the degradation and accumulation of these compounds are still unknown and thus many more studies and approaches are required in order to insure healthy food and stop the current obesity epidemic. Everything that is added to our food should be carefully analyzed.
Hey there!
I think you mean the Finches. Each Finch has a beak that is very similar to other beaks on the other islands. This shows that they are related. Their beaks change so that they can live better in their environment. They all had a common ancestor.
I hope this helps!
Explanation:
2. distribution and abundance of organisms
3. speciation of plants
4. Antarctic convergence
Geographical isolation is the physical barrier dividing the communities. It usually stops the gene flow between species in a process called allopatric speciation, contributing to reproductive isolation.
Further Explanation:
Spontaneous modifications within the genome may arise during the cycle of cell division, called mutations. These errors occur as copies of the DNA are produced within the cell; mutations may range from small modifications, called single nucleotide polymorphisms, to large-scale deletions and multi-gene additions.
These mutations form variants which, within a population, become stable, resulting in the formation of separate, genetically distinct populations called species. Apart from allopatric speciation, new species arise through several other evolutionary mechanisms such as:
- peripatric speciation— like allopatric speciation, however, one group is much smaller, making the unique characteristics more notable, or distinct
- parapatric speciation— sub-populations in a large geographic region develop reproductive isolation by mating with those nearby, but continue to undergo reproductive isolation;
- sympatric speciation-absence of physical barriers that impede the passage of genes; reproductive segregation by many variants of the same genes called polymorphisms
