If the genotype of the nonrecombinant progeny of a three-point testcross is A B C and the genotype of the double-crossover progeny is a B C, which gene is likely in the middle of the three loci?

Gene A

Explanation:

If the three points test cross genotype A B C is crossed withe the double crossover progeny BC, the resulting gene will have A at the centre of the three loci

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.

not always but somethings can be reproduced in a laboratory.
