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".
Some disorders caused by recessive alleles include cystic fibrosis, sickle cell anemia, and phenylketonuria. These disorders manifest when an individual inherits two copies of the mutated gene, one from each parent.
Diploid 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.

A blood type
Abundant body hair
Astigmatism
Baldness (in male)
Broad lips
Broad nose
Dwarfism
Hazel or green eyes
High blood pressure
Large eyes
Migraine
Mongolian fold
Nearsightedness
Rh factor
Second toe longest
Short stature
Six fingers
Webbed fingers
Tone deafness

Genetic disorders are caused by?
Genetic disorders are caused by abnormalities in an individual's DNA, either through mutations or changes in the genes. These abnormalities can be inherited from parents or can occur spontaneously during a person's lifetime. Genetic disorders can affect various aspects of health and development.
Which alleles is the recessive alleles?
Recessive alleles are alleles that are masked or overshadowed by dominant alleles. In a heterozygous genotype, the recessive allele does not show its effects. Only in a homozygous recessive genotype does the recessive allele manifest its trait.
What type of alleles mask recessive alleles?
Dominant alleles :-)
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.
When two recessive alleles are inherited the trait is observed?
When two recessive alleles are inherited, the trait associated with those alleles is observed because there is no dominant allele to mask its expression. This results in the individual displaying the recessive trait.

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 combinations of alleles could produce a trait controlled by a recessive alleles?
recessive + recessive or tt
What is the result of two recessive alleles joined?
When two recessive alleles are joined together in an individual, the individual will display the recessive trait associated with those alleles. This is because recessive alleles only express themselves when a dominant allele is not present.
What type of alleles mask recessive alleles?
Dominant alleles :-)
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.
How are Dominant and recessive alleles are represented in Punnet Square?
Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.
