Many different types of disorders can be found if multiple alleles occur, for example, if your have 3 number 21 chromosomes, then you will have a disorder called "Down syndrome", so the answer is "Yes".

∙ 14y agoDiploid organisms inherit one set of chromosomes from each parent. So there are 2 alleles for every gene. If one parent is homozygous dominant and the other is heterozygous with the recessive allele, there is a 50% chance the heterozygous parent will pass on the recessive allele.
For the recessive trait to be expressed, the progeny must pick up a recessive allele from both parent, so either the parents must be homozygous recessive or heterozygous and pass on the recessive allele.
Example, two heterozygous individuals have a 50% chance of passing on recessive allele.
50%*50% = 25% recessive phenotype.

Genetic disorders are caused by?
Genetic Disorders are caused By a change in a person's DNA. Recessive alleles is the most human genetic disorder.
Which alleles is the recessive alleles?
recessive alleles are the ones with small letters, for example in Rr, the recessive is the r.
How are dominant and recessive alleles are represented in a punnet square?
Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.
What type of alleles mask recessive alleles?
Dominant alleles :-)
A recessive allele is represented by an letter?
Most of the time a recessive allele is expressed using lower case letters in comparision to the upper case dominant alleles.
Genetic disorders are caused by?
Genetic Disorders are caused By a change in a person's DNA. Recessive alleles is the most human genetic disorder.
What evidence is there that the long and round alleles did not become blended?
A number of genetic disorders are caused when an individual inherits two recessive alleles for a single-gene trait. Recessive genetic disorders include Albinism, Cystic Fibrosis, Galactosemia, Phenylketonuria (PKU), and Tay-Sachs Disease. Other disorders are also due to recessive alleles, but because the gene locus is located on the X chromosome, so that males have only one copy (that is, they are hemizygous), they are more frequent in males than in females.
Is tay-sachs caused by codominant alleles?
No, autosomal recessive

What are some human traits that are caused by multiple alleles?
The heredity of the ABO blood groups are governed by multiple alleles.
What combinations of alleles could produce a trait controlled by a recessive alleles?
recessive + recessive or tt

What can be dominant or recessive?
Alleles can be dominant or recessive
Is sickle cell anemia and cystic fibrosis caused by recessive alleles?
im not really sure, but i think it is.
