What should be the genotypes of the parent flowers (P generation) if he wants to ensure that all of the
flowers in the F, generation are tall and yellow?

If the trait for tall and trait for yellow are recessive: ttyy and ttyy

If the trait for tall is dominant and trait for yellow is recessive: TTyy and TTyy, Ttyy and TTyy

If the trait for tall is recessive and trait for yellow is dominant: ttYY and ttYY, or TtYy and TTYY

If the trait for tall is dominant and trait for yellow is dominant TTYY and TTYY, or TtYy and TTYY

What should be the genotypes of the parent flowers (P generation) if he wants to ensure that all of the  flowers in the F, generation are tall and yellow?

YYTT x YyTt= YYTT, YyTt, YYTT and YyTt

The genotype of the parent flowers is YY and Yy in order to produce all generation that are tall and yellow

Explanation:

examples of nucleic acids are deoxyribonucleic acid (dna) and ribonucleic acid (rna).

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.
