NGSS.HS-LS3-2

Gregor Mendel's "P" generation consisted of homozygous purple flower plants crossed with homozygous white flower plants. What were the results of this cross?

• 100% heterozygous purple flower offspring since purple is dominant.
• 100% homozygous white flower offspring since white is recessive.
• 100% homozygous purple flower offspring since purple is dominant.
• 50% purple flowers and 50% white flowers
