In zebrafish, three genes have been mapped on the third chromosome, in the order fiz---6 m. u.---myob14 m. u.sufi The wild-type allele of each gene is dominant. A strain that is fiz myob sufi / + + + is testcrossed, and there are 1000 offspring fish. 1) How many wild-type offspring would you expect to see in these 1000 offspring?
2) How many fiz + + offspring would you expect to see in these 1000 offspring?
3) How many + + sufi offspring would you expect to see in these 1000 offspring?
4) How many + myob + offspring would you expect to see in these 1000 offspring?

What controls activities within a eukaryotic cell?

During crossing-over, a. genetic material is exchanged between nonsister chromatids, resulting in new combinations of alleles. b. nonsister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles. c. one homologous chromosome of a tetrad is exchanged with another tetrad, resulting in new combinations of alleles. d. sister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles. e. genetic material is exchanged between sister chromatids, resulting in new combinations of alleles.
