Flowers “self pollinate”

• Contain both male and female structures

• Bees do most of the work

Scientists use an ​ (a)   to symbolize a dominant allele. We use a ​ (b)   to symbolize a ​ (c)   allele. If the allele is recessive, it's effects may not be seen if the organism also has a ​ (d)   allele.

• uppercase letter
• lowercase letter
• recessive
• dominant
