Total magnification when the objective is at high power (also called 40x) is:

1 answer:

8 0

To find the total magnification, you multiply the power times the power of the ocular lens. The ocular lens is usually 10x power. So, if the power is 40x, you would multiply 40x*10x. That would make the total magnification 400x. So, your answer is c.

A test cross was made between true-breeding EEWW flies and eeww flies. The resulting F1 generation was then crossed with eeww fl

Anton [14]

Explanation:

<h3><u>If the genes were linked:</u></h3>

<u>Parental cross: EW/EW X ew/ew</u>

F1 genotype: EW/ew

F1 Gametes:

- Parentals (more abundant): EW and ew

- Recombinant (less abundant): Ew and eW

<u>Test cross: EW/ew X ew/ew</u>

<u>F2 genotypes:</u>

Parentals: EW/ew; ew/ew;
Recombinant: Ew/ew; eW/ew

<h3><u>If the genes are not linked:</u></h3>

<u>Parental cross: EEWW X eeww</u>

F1 genotype: EeWw

F1 gametes: EW, Ew, eW, ew. Genes assort independently, so all of the possible gametes of the F1 individual will have the same probability.

<u>Test cross: EeWw X eeww</u>

<u>F2 genotypes:</u>

1/4 EeWw, 1/4 Eeww, 1/4 eeWw, 1/4 eeww
