A husband and wife have two sons one boy has a straight thumb while the other has a bent thumb what causes the difference?
The brothers have different alleles. They received different alleles from their parents
What type of alleles mask recessive alleles?
Dominant alleles :-)
What are the multiple forms of genes called?
Alleles are genes that exist in multiple forms.
What term describes a pair of alleles that are the same?
Alleles that are the same = homozygous Alleles that are different = heterozygous
When more than two different alleles control a trait?
The presence of more than two alleles that control a trait is called multiple allele. An example of this is the group gene of ABO blood that has three alleles.

The number of alleles of a certain type divided by the total number of alleles is what?
Alleles Frequency
Compare homozygous alleles to heterozygous alleles?
When the alleles are identical, the individual is homozygous for that trait. While if the pair is made of two different alleles.
What type of alleles does a plant have?
unlike alleles
