|
traits
|
characteristics that are inherited

the transfer of the male pollen grains to the pistil of a flower

|
|
dominant

|
|
recessive
|
trait of an organism that can be masked by the dominant form of a trait
|
|
|
law of segregation
|
madelian principle explains that because each plant has two different alleles, it can produce two different types of gametes. during fertilization, male and female gametes randomly pair to produce four combinations of alleles.
