Two true-breeding parents, one who is a Iceberg and Balsamic lover, and the other who is Romaine, Thousand Island lover, are mated. One of the F1 offspring is back-crossed to a Iceberg, Balsamic lover. If the observed counts of each phenotype from 500 F2 offspring are: Ice/Ba Ro/TI Ice/TI Ro/Ba 240 240 10 10 what is the estimated recombination fraction between the two genes?A.

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.
