Snapdragons, a flowering plant popular with gardeners, can have red, white, and pink colored petals. When snapdragons with red petals (RR) are crossed with snapdragons having white (rr) petals, the offspring have pink petals. The pink coloration (Rr) is a phenotype in between the red and white parental phenotypes. What is this kind of inheritance pattern called? A) classic dominance B) bipolar inheritance C) incomplete dominance D) recessive inheritance 8) Among a species of butterflies, the color blue (B) is a dominant trait. Yellow color (b) is a recessive trait. If a pure blue butterfly (BB) mates with a pure yellow (bb), what will the offspring look like?

The correct option are as follows:
7. This type of inheritance pattern is called INCOMPLETE DOMINANCE. The correct option is C.
In inheritance, incomplete dominance is said to occur when an offspring expressed a characteristic that is intermediate between one parent dominant trait and the other parent recessive trait. An example of this in human occur when a straight haired {dominant phenotype} man married to a curly hair {recessive phenotype} woman give birth to a wavy hair {intermediate product} son.

8. If a pure blue butterfly [BB] mates with a pure yellow [bb] butterfly, they will give birth young butterflies who all have blue color. This is because blue is the dominant trait. The genotype of the offspring will be Bb, that is, they will have one dominant and one recessive gene.
