monitta

Answer:

•The relationship between the twist and the wild type flower in the first crossing is known as a COMPLETE DOMINANCE

•The relationship between the forked and the wild type flower in the second crossing is also known as a COMPLETE DOMINANCE

•The relationship between the pale and the wild type flower in the third crossing is known as an INCOMPLETE DOMINANCE

Explanation:

A complete dominance is characterised by having one of the genes (the dominant gene) in an heterozygous condition, completely masking the effect of the other (the recessive gene) of thesame allelic pair. E.g. if the genes in allelic is represented with Aa, "A" is said to completely dominate "a" if it does not allow "a" to Express itself phenotypically.

The heterozygous condition is always the result of the F1 generation

and the F2 generation of a Complete dominance is always characterised by a phenotypic ratio of 3:1 which is in line with the results gotten from the first crossing and the second crossing as stated in the question.

An complete dominance is characterised by having an intermediate progeny in the F1 generation which was evident in the result of the third crossing. Also a phenotypic ratio of 1:2:1 in the F2 generation is also a characteristic feature of an Incomplete dominance relationship which was also evident in the third crossing.
