This is a positive mutation, because the offspring will survive longer to reproduce. Their offspring will then carry the same genes passing it off to their offspring. The other color mice that did not blend into its environment will soon be extinct, leaving only the mice that can blend in.

"In the snake experiment, what was the basis for the hypothesis that mimic species benefit from looking" like unrelated harmful
Fantom [35]

Answer:

The contrast in coloration was pivotal to determine if predators attack snakes based on their colors.

It was for studying MIMICRY in snakes.

Assuming all the.snakes were the same the number of attacks will not indicate anything about the effect of the colored rings.

This question on the need for provision of a controlled experiment during experimental investigation. Thus in order to test the effect of a particular condition,another contrasting condition must be provided to determine if the condition under investigation is the actual results obtaned or the influence of other factors in the environment or in the experiment.

The change in the color of the ring is the VARIABLE .In the artificial snake the variable is the presence of this coloed rings against its absence in this snake.

since it changes in the artificial snake

Your first cousin died of tay-sachs disease (autosomal recessive, incidence 0.09%). you are not affected, nor is anyone else in
AlexFokin [52]
<span>25%

   Starting from my First cousin family, I know for sure that the Uncle is is a carrier (Aa) and he must have married a wife who is also a carrier (Aa) and that is how they got an affected son. Thus, this leads to the fact that either both of my grandparents are carriers (Aa x Aa) or only one of them is a carrier (Aa x AA). As a result, the chances that my mom (who is related to the uncle who has a defected child) is a carrier is either (2/3 or 1/2) depending if my grandparents genotype, respectively. Thus, if my mom chances of being a carrier is 1/2 then my chance of being a carrier is 1/4. (given that my dad is not a carrier b/c CF is a rare disease) However, if my mom chance of being a carrier is 2/3 then my chance of being a carrier is (2/3)x(1/2)=(1/3) As a result, I could either be 1/4 or 1/3. But since the answer only provide the choice of 1/4 and not 1/3. This leave 25% is the correct answer.</span>

The false spider mite, Brevipalpus phoenicis, has only two chromosomes. Which of the following pieces of evidence would allow yo
Reptile [31]

Answer:

The correct answer is - a. If these two mite chromosomes have different genes at different loci.

Explanation:

If it is 2n= 2, it means that it is diploid and has two sets of chromosomes in which one set comes from mother and the other from father which means parent's genes contribute to diploid equally. Both sets of chromosomes form homologous chromosome pair. Each homolog of the pair has the same gene at the same loci in diploid and if it has not the same homologous gene at the same loci these are haploid.
