A breeder wants to set up a program to produce zebrafish with long fins. Having long fins is a dominant trait compared to the sh
ort-finned wild type. Before she can market her zebrafish, she needs to perform a test cross on the long-finned fish she plans to use as a breeder. How can she tell whether her fish are homozygous or heterozygous for the long-finned trait?
Continuous long-finned offspring from several cross test
Explanation:
She must severally test cross betweethe long-finned fish and the short-finned fish; if the offspring are always long-finned, the long-finned parent could probably be homozygous
No- the question isn’t too clear but since the plasma membrane is the only part of the cell responsible for movement of molecules, there doesn’t need to be other molecules to replicate the same process
