Answer: A) 2 gametes will have 2 of these chromosome and 2 will have 0 of these chromosomes.

Explanation: Meiosis is a division process in sex cells. Meiosis has two stages: In Meiosis I duplicated homologous chromosomes (one pair from mother and one pair from father) are separated in two daughter cells. Later those cells begin meiosis II where chromatids of each chromosome are separated in two daughter cells. If homologous chromosomes fail to separate during meiosis I, the result would be 2 diploid (contain two copies of that chromosome) gametes for that chromosome and 2 gametes without that chromosome.

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
