How many alleles is a gene controlled by?
A gene is controlled by two alleles, one inherited from each parent. These alleles can be the same (homozygous) or different (heterozygous), influencing the expression of the gene and determining an individual's specific traits.
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
How do combination of alleles on your genes determine your phenotype?
Your phenotype is a characteristic of how you look, for example if you have brown or blue eyes. You inherit one allele for each characteristic you have from you mom and dad. Say your mom gives you a blue eyes allele and your dad gives you a brown eyes allele. Since brown eyes usually dominate over blue eyes, you would most likely be heterozygous for brown eye color, and you would have brown eyes. This would be represented by Bb, the B standing for brown eye color, the dominant trait, and the b standing for blue eye color, in this case the recessive trait. So, depending on what alleles you receive from your parents, you may look different than, for example, than your siblings do because they got a different set of alleles. This is possible because your parents both have 2 alleles, but they only give you one of each, so if both your parents give, for example, your sister a blue eye allele, she will most likely have blue eyes, even if you have brown.
What are the two types of alleles traits?
The two types of alleles for traits are dominant alleles and recessive alleles. Dominant alleles are expressed when at least one copy is present, while recessive alleles are only expressed when two copies are present.
What is the allele frequency?
The distribution of alleles in a population - APEX
How many alleles control blood type in humans?

For a gene that has multiple alleles more than 2 what is the maximum number of different allels a normal individual can have?
2. Even though there are multiple alleles for the same characteristic in the general population, an individual can only have two.
What is the definition of homozygus?
Homozygous -It is the characteristic of having two identical alleles at the same locus of sister chromatids.homozygous means having identical alleles at corresponding chromosomal locus or the specific site of a particular gene on its chromosome
How many alleles is a gene controlled by?
A gene is controlled by two alleles, one inherited from each parent. These alleles can be the same (homozygous) or different (heterozygous), influencing the expression of the gene and determining an individual's specific traits.

How many characteristics does each gene contral?
2 genes control each characteristic of an offspring. x
What is the difference between a gene and trait?
Trait is a characteristic like: tall, short, black eyes, blue eyes Trait is determine by the genes: your gene is a little section on chromosome. A gene that control 1 trait usually have 2 alleles, for ex: Blue eyes is : Bb (b or B are the alleles make up the gene that determine the trait.) hope this help for whoever confuse!
How many alleles for a trait are there?

What is gene pair consists of two dominant alleles or two recessive alleles?
A gene pair that consists of 2 dominant or 2 recessive alleles is considered homozygous dominant or homozygous recessive.
How many alleles for one trait can an individual have?
An individual can have a maximum of two alleles for one trait, as they inherit one allele from each parent. These alleles can be the same (homozygous) or different (heterozygous) for a specific trait.
What is an example of a heterozygous genotype?
Genotype means the particular alleles an individual has alleles are just a kind of gene and a gene is a section of DNA which codes for a particular protein or characteristic in an organism. Heterozygous is when a person has 2 alleles for the same characteristic like hair you could have the allele for both blonde or brown hair but due to the blonde one being recessive (ie not as powerfull/strong), you would not know. So, an example would be WBWb: B = Brown b = blonde W= allele so for hair a heterozygous person would have the genotype WBWb.
Example of heterozygous?
homozygous means you have two alleles with the same characteristic. example; two alleles for brown eyes recessive means that when you have two different alleles, one of then doesn't show its trait example; one allele for brown eyes and one allele for green eyes gives brown eyes, because green eyes are recessive people who have green eyes have homozygous recessive alleles for green eyes (two alleles for green eyes)
