For a person with blood type A- (A negative), they can be transfused with either blood type A negative , or blood type O negative.
This is because any other blood type will immediately be rejected by their body.
A person with blood type A negative has got antibodies against any other blood type which has a rhesus positive factor as well as antibodies against any other blood type of a different group such as B and AB, even if they are rhesus negative.
Therefore because of the rhesus negative factor, a person with blood type A negative can only be transfused with rhesus negative .
Answer:
Option D: O-
Explanation:
They can also receive blood type A-, but that's not one of the options on the test.
Answer:
1. Incomplete dominance has occurred
2. A phenotypic ratio 1 Blue : 2 pale blue : 1 white will be obtained.
Explanation:
Mendelian principle states that one allele is capable of masking the expression of another i.e. one allele is dominant and the other one is recessive. Genetic scenarios that have gone against this principle has been observed. One of them is the concept of INCOMPLETE DOMINANCE, which is a case where one allele is not completely dominant over the other, hence, they combine to form a third intermediate phenotype different from both parents.
This is the case in the question where the the blue allele (B) fails to completely dominate the white allele (W), instead it forms an heterozygous plant (BW) with a different phenotype (pale blue) that is a blending of the two parental phenotypes (blue and white). This heterozygote (BW) is formed in the F1 generation.
If the F1 offsprings (BW) are self-crossed, four possible offsprings will be produced using a punnet square. This offsprings will have genotypes: BB, BW, BW, and WW. This depicts a genotypic and phenotypic ratio of 1:2:1 i.e. 1 blue (BB) : 2 pale blue (BW) : 1 white (WW).

The answer is A and by the way, you spelled his first name wrong. It's spelled Louis.

Answer:
Explanation:
A scientific hypothesis is a prediction or idea which should be tested to answer the natural phenomenon.
The hypothesis can be evaluated through the following ways:
1. Hypothesis should be based on the previous research related to the scientific question.
2. Hypothesis should be tested by designing and performing the experiments.
3. The result or data must disprove or prove the hypothesis.
When evaluating a scientific hypothesis, designing and performing experiments is best. The experiment's results should agree or contradict the hypothesis's predictions. The more experiments that consent, the more likely the hypothesis is accepted as a useful description of nature.
When evaluating a scientific hypothesis, designing and performing experiments is the best approach. Experiments should be systematic observations or measurements made under controlled conditions where a single variable changes. The experiment's results should either agree or contradict the hypothesis's predictions. If the results are inconsistent, scientists must discard the hypothesis and develop an alternative. If the results agree, it does not prove the hypothesis is correct. However, the more experiments that consent, the more likely the hypothesis is accepted as a useful description of nature.
