Does Tay-Sachs disease have single cells or multiple alleles?
Klooper
Multiple mutations are responsible for Tay Sachs Disease. For example, Tay Sachs in the french Canadian population may be due to a different mutation then people of eastern European Jewish descent with Tay Sachs.
any mutation that causes the absence of the enzyme Hexosamindase (Hex-A) is a mutation that can cause a Tay Sachs genotype/phenotype within an individual

Is huntington's disease determined by multiple alleles?
No. This is a single gene disorder. If at least one allele has the huntington's mutation, the person will eventually develop the disease.
Is the three alleles of the single gene that controls blood type is said to be what alleles?
multiple alleles
What is multiple aleles?
Multiple alleles indicates that either the study is being conducted on alleles at more than one gene locus, that the characteristic being studied is controlled by several alleles at different loci or that there are two or more alleles at a single gene locus.
Which is most inclusive A. Allele B. Genotype?
single genes wiht multiple alleles
What is the difference between alleles and multiple alleles?
Alleles refer to different versions of the same gene. So a single gene can have multiple alleles. For example in fruit flies there is a single gene that controls eye color, and the eye color of the fly depends on the alleles they have for that gene (since they have two copies of every gene, being diploid). A polygenic trait refers to any inheritable trait that is controlled by multiple genes, and each of these genes can have multiple alleles. For example, eye color in humans is a polygenic trait. There are at least three different genes, each with multiple alleles, that determine eye color in humans. Polygenic traits don't follow patterns of mendelian inheritance. So in summation the difference is multiple alleles refers to different versions of one gene and polygenic traits refers to a single trait which is controlled by multiple genes (each with multiple alleles) Yes, or: Multiple alleles are "the existence of more than two alleles (versions of the gene) for a genetic traits. Polygenic traits are "[characteristics of organisms that are] influenced by several genes." So multiple alleles are more than two alleles for one trait, and polygenic traits are one trait that is influenced by multiple genes. This information came from my biology textbook, "Biology: Principles and Explorations" by Holt, Rinehart, and Winston.
What is the difference between a single gene and a polygenics trait?
A polygenic trait is a trait in which multiple sets of alleles are used to determine the trait, whereas in a single gene trait aka. a Mendelian trait, only one pair of alleles is used.
What are the characteristic of multiple alleles?
1) Multiple alleles are always on the same location (locus) on the alleles.2)they always effect the same character.3)They always occupy the same gene locus on chromosome.4)no crossing over is known to occur on chromosome.5)a single multiple allelic series affects only one trait _eye color etc
What is a single cyst or multiple cysts usually benign in the breast?
fibrocystic breast disease
What three ways are human traits controlled?
Human traits are controlled by a combination of genetic factors (inherited from parents), environmental factors (such as diet and lifestyle), and epigenetic factors (changes in gene expression without changes in the underlying DNA sequence). These factors interact in complex ways to influence the development and expression of human traits.
What are both inherited alleles called?
Genetic makeup formed from both inherited alleles together is called a genotype. Homozygous alleles would be a pair of identical alleles for a single trait. Heterozygous is different alleles for a single trait.
What do geneticists call alleles that are both expressed in the phenotype when they are together?
Genetic makeup formed from both inherited alleles together is called a genotype. Homozygous alleles would be a pair of identical alleles for a single trait. Heterozygous is different alleles for a single trait.
What is three or more forms of a gene that code for a single trait are called?
A gene can have multiple forms, which are called Alleles. While a single gene may code for a trait in an organism, when multiple alleles exist for that gene, each different may produce a different character of that trait. For example, a person has two copies of the gene that codes for ABO blood type. There are three different alleles for this gene, A, B and O. This results in six different combinations of the alleles that the person can have (the genotype), which in turn results in four expressions of the gene in the person (called the phenotype), which is the blood type of the person.
