A typical fruit is derived from a single carpel or several fused carpels and is called a simple fruit. First, they regulate the process of seed development. Flowers are the reproductive part of most plants. An aggregate fruit is one that develops from numerous carpels that are all in the same flower; the mature carpels fuse together to form the entire fruit, as seen in the raspberry. Homozygous recessive expression of the W gene (ww) coupled with homozygous dominant or heterozygous expression of the Y gene (YY or Yy) generates yellow fruit, and the wwyy genotype produces green fruit.
