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 heterogenous in genes?
when an organism has 2 different alleles for a trait an allele is a specific gene examples: Blond hair, Blue eyes, Big feet
What is the number of alleles in a gene?
An allele of a gene resides on a chromosome; as there are typically two chromosomal copies in an individual Cell, there are typically two alleles of each and every gene in the individuals genome, or its genetic complement.
How many alleles is a gene controlled by?
2
What is the genotype for homozygous green?
2 green alleles.
How many alleles control blood type in humans?
2
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
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 are the characteristic of multiple alleles?

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 characteristics does each gene contral?
2 genes control each characteristic of an offspring. x
What is heterogenous in genes?
when an organism has 2 different alleles for a trait an allele is a specific gene examples: Blond hair, Blue eyes, Big feet
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.
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 a trait are there?
2
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)
Differences between dominant and recessive?
Dominant is stronger than recessive. So you can only have the phenotype ( visual characteristic ) of a recessive allele if you have 2 recessive alleles in your DNA , and other combination the dominant allele would be predominant
