Alleles are different forms of a gene that can result in variations in traits. These differences can arise from mutations, genetic recombination, or genetic drift, leading to variations in the DNA sequence that ultimately determine the specific characteristics of an organism.

How many alleles for one trait are normally found in the genotype of an organism?
An organism has two alleles for one trait. If the two alleles are the same, the individual is homozygous for that trait, and if they are different, the individual is heterozygous.
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.
Do codominant alleles assort independently?
Yes, codominant alleles assort independently during Mendelian inheritance. This means that the inheritance of one pair of alleles does not influence the inheritance of another pair of alleles on different chromosomes. Each allele segregates independently into gametes during meiosis.
What genotype has different alleles?
A heterozygous genotype has two different alleles for a given gene, one inherited from each parent. For example, in the genotype Aa, the individual has one dominant allele (A) and one recessive allele (a) for that gene.
An what is a different version of the same gene?
A different version of the same gene is called an allele. Alleles are variations in the DNA sequence of a gene that can result in different traits or characteristics. Individuals inherit two alleles for each gene, one from each parent.
Why do population have variations in certain traits?
For one thing, different individuals have different alleles.
What is another name for hybrid alleles?
Another name for hybrid alleles is heterozygous alleles. This term refers to having two different versions of a gene in an individual's genetic makeup.
What is a codominance?
Co-dominant allele is the one that shows dominance with another allele from a different loci. Basically its one of the following: 1) two different alleles at a locus are responsible for different phenotypes. 2) two alleles that affect the phenotype of the heterozygote. For instance ab blood groups
What is another term for heterzygous?
Another term for heterozygous is "heterozygote." This term refers to an organism that has two different alleles for a specific gene, one inherited from each parent. In contrast, an organism with identical alleles for that gene is called homozygous.
What happens to the allels durnig meiosis?
The alleles of 2 or more different gene pairs assort independently of one another.
When two different alleles appear on one gene but one of those alleles appears in the phenotype?

How many alleles for one trait are normally found in the genotype of an organism?
An organism has two alleles for one trait. If the two alleles are the same, the individual is homozygous for that trait, and if they are different, the individual is heterozygous.
When two alleles in a pair are different?
When the alleles are different the organism is heterozygous for that trait. Another way of putting it is to say the genotype is heterozygous for that trait. The dominant allele will be seen in the phenotype ie what is displayed.Most traits are governed by more than one pair of alleles.
What is the two alleles letters for one traits that are different?
The two alleles for a trait that are different are represented by two different letters, typically one uppercase and one lowercase. For example, if the trait is flower color, the alleles could be represented as "R" for a dominant red color and "r" for a recessive white color. This combination of different alleles is referred to as heterozygous.
If a gene has one completely dominant allele and two recessive alleles how many different traits can these alleles produce?
A gene with one completely dominant allele and two recessive alleles can produce two different traits. The dominant allele will express its trait regardless of whether it is paired with another dominant or a recessive allele, while the two recessive alleles will express their trait only when paired together. Therefore, the possible combinations of alleles result in one dominant trait and one recessive trait.
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 difference between segregation and independent assortment?
Every diploid cell has two alleles for every gene. Segregation means that when these alleles go through meiosis to create gametes, they will segregate from one another, and each of the haploid gametes will end up with only one allele.Independent assortment comes into play when you are looking at how the alleles of two genes separate. As long as each gene lies on a different chromosome, then the alleles of these genes will assort themselves independently of one another when the haploid gametes are formed in meiosis. Each haploid gamete can end up with a different combination of alleles of these two genes.
