Answer:
I would say C because in number one, the tests were never repeated
Explanation:
do you mean
this question??
Experiment 1: A group of students tested to see if the acidity of water affected pea plant growth. The students followed a logical method and performed their experiment once, using control and experimental groups. Their results supported their hypothesis.
Experiment 2: A group of students tested to see if bacteria growth in water was affected by acidity. The students used control and experimental groups. They repeated their experiment several times and found the results were the same.
Which experiment most likely has greater reliability?
A. Number 1 because it follows a logical method
B. Number 2 because the experiment was repeated
C. Number 2 because the experiment was repeated and the results were always the same
D. Number 1 because it has control groups

Answer:
12%
Explanation:
The genes E/e and F/f are 24 cM apart.
- E_: elongated wings
- ee: small wings
- F_: five stripes
- ff: four stripes
A distance of 24 cM means that the frequency of recombination between the two genes is 24%.
The cross Ef/eF x ef/ef would produce the following offspring:
- Ef/ef: Parental; elongated wings and four stripes
- eF/ef: Parental; small wings and five stripes
- EF/ef: Recombinant; elongated wings and five stripes
- ef/ef: Recombinant; small wings and four stripes
The total percentage of recombinant gametes is 24%, and there are two possible recombinant gametes, so each of them appears in 12% of the cases.
The individuals with elongated wings and five stripes have the recombinant genotype EF/ef, therefore the percentage of the offspring with this phenotype is 12%.
