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?

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

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
