Explanation:
A controlled experiment is repeated many times to ensure that the results are accurate
Answer:
Population density and transportation, Switzerland (technically), Africa
Explanation:
population density means of the population is close together and as such it can spread easier. Modern transportation I.E. buses, planes, railroads can transport large numbers of infected people to several different places within a nation and lead to more cases Switzerland is the highest per capita it has 1340 confirm cases per 1 million people however that's likely because they are able to test a large amount of the population at once whereas a larger Nations such as the u.s. or China is unable to test all their population at once and get accurate results. Africa is least affected due to not having a lot of population some together with the exception of some major cities and more industrialized countries such as Egypt and also Lacking the modern transportation systems available in more industrialized nations they don't have as many trains they don't really have too many planes able to transport infected people everywhere

Answer:
The parents must be Tt, Tt
Explanation:
Based on these results, we can conclude that each of the parents will have one dominant (T) and one recessive allele (t). We can prove this by drawing the Punnett square:
T t
T TT Tt
t Tt tt
We can see that the offspring will have the Tt genotype in two cases, the TT genotype in one case, and the tt genotype in one case, as well. Now we need to do some basic math. Two out of four is 50% (Tt - 50%), and one out of four is 25% (TT - 25%, tt - 25%).
This means that the parents must be Tt, Tt.
