multipule alleles(novanet)
The genotype of a pea plant with two alleles YY is homozygous dominant. This means that both alleles for the trait in question are the same and dominant. In this case, the plant will express the dominant trait associated with the YY genotype.
Alleles Frequency
Blood type inheritance is determined by three alleles (A, B, O), but an individual inherits only two alleles, one from each parent. This means a baby can have only two alleles for blood type, such as AO or BO, even though three alleles exist in the population.
if the pea plant has 2 recessive alleles then the plant is gonna come out short.but if it has 1 recessive and one dominant allele then the plant turns out tall, because the dominant allele can be present without the recessive allele.

You cross a pure-breeding plant with red flowers and a pure-breeding plant with white flowers. All the offspring have red and white speckled flowers. What type of allele relationship does this show?

Alleles come in pairs. Organisms inherit one allele from each parent organism with sexual reproduction. If the alleles are the same, they could be said to be pure alleles. The science term is monozygous.

Dominant alleles :-)
There are three alleles for blood type: IA=Blood type A IB=Blood type B i=Blood type O The alleles for blood type A and B are codominant so when someone contains the IA and IB alleles, their blood type is AB.
wha- dominant? alleles?
Three common blood alleles are A, B, and O. A person's blood type is determined by the combination of these alleles. People with type A blood have A alleles, people with type B have B alleles, people with type AB have both A and B alleles, and people with type O have neither A nor B alleles.
