Answer:
cant really answer much since you need the class results for these. but i can simplify question 1. so, does the class results prove that the traits made my dominant alleles are the most common? or in other words, are traits made by dominant alleles most common in the class results?
number 4 is yes because there are more possibilities that the dominant trait will occur than the recessive trait. therefore, it is more common and the conception is correct
Answer:
The results are precise but not accurate
Explanation:
Precision is the term that refers to the degree of agreement between measured results. This means that the measurements of the finished system are very similar and with equal differences, under the same conditions.
An example of this is the results shown in the question above, which are very similar. In addition, these results do not have the "real and absolute value" and therefore are not accurate.
The bacteria was not killed off. In those three days symptoms had stop because the bacteria was dormant. They must have been activated because Jim provided a suitable environment for their growth
Answer;
He conducted an experiment with breeding pigeons.
Explanation;
The pigeons provided the perfect animal to test his theory of selection for quite a number of reasons including its trait diversity from wing structures to color patterns to size to flight patterns. From these experiments he concluded that by natural selection of randomly occurring traits that make species better suited for survival and reproduction, evolve in the astounding diversity of organisms on Earth today.
Answer:
The mentioned characteristics of variability are witnessed because of the phenomenon known as X chromosome inactivation in heterozygous females. As females possess two X chromosomes, they actually should not possess any color blindness.
The phenomenon of X-chromosome inactivation takes place in a random manner at the time of embryo development. During this only one X chromosome is inactivated. If the chromosome comprising the defective gene is inactivated, the individual will possess normal vision.
If the chromosome comprising the usual gene gets inactivated than the individual will be color blind. In the given case of female, X inactivation took place in one eye. The inactivation of normal alleles has taken place and thus she possesses normal vision with one eye and is color blind in the other eye.
