How many dominant alleles do you need to inherit that particular characteristic eg brown eyes?
To express a dominant characteristic, such as brown eyes, you need at least one dominant allele. In a diploid organism, which has two alleles for each gene (one inherited from each parent), possessing either one or two copies of the dominant allele will result in the expression of that trait. Therefore, having just one dominant allele (heterozygous) is sufficient to exhibit the dominant characteristic.
What else can I help you with?
If offspring receive two sets of instructions for each characteristic how are the offspring's traits determined?
Offspring inherit two sets of instructions, or alleles, for each characteristic—one from each parent. These alleles can be dominant or recessive, and the combination of these alleles determines the offspring's traits. If a dominant allele is present, it typically masks the effect of a recessive allele, leading to the expression of the dominant trait. The specific combination of alleles received from both parents ultimately shapes the offspring's phenotype.
Which refers to the diffferent forms of genes representing a certain trait?
Alleles represent the different forms of genes that code for a particular trait. Alleles can be dominant or recessive, and individuals inherit two alleles for each gene, one from each parent. These alleles determine the physical characteristics of an organism.
What are facts about allele?
Alleles are different forms of a gene that can occupy the same position on homologous chromosomes. Alleles can be dominant or recessive, influencing the expression of a particular trait in an individual. Diploid organisms inherit two alleles for each gene, one from each parent, which can be the same (homozygous) or different (heterozygous).
How do you inherit alleles?
You inherit alleles from your parents through the process of reproduction. Each parent contributes one allele for each gene, resulting in a pair of alleles for every gene in the offspring. The combination of these alleles determines traits, with some alleles being dominant and others recessive. This genetic inheritance follows Mendelian principles, where allele segregation and independent assortment play key roles.
How come there are no carriers in genetic diseases caused by dominant alleles?
If carried on a dominant allele, you either inherit it- and have the disease- or you don't- and do not have the disease, nor the gene that causes it. If you don't have the gene, you can not pass it to your offspring.

Why a student inherited a recessive phenotype of a particular characteristic even both the parent are phenotypically dominant for the characteristic?
May be the parents are heterozygous.So, the percentage for the students to inherit a recessive phenotype from the parents is 25%.

What type of inheritance pattern (are the A and B alleles to each other (Autosomal dominant-Regular dominant-recessive relationship, X linked, co-dominant, incomplete dominant)?
Incomplete dominance
How do you inherit alleles?
You inherit alleles from your parents through the process of reproduction. Each parent contributes one allele for each gene, resulting in a pair of alleles for every gene in the offspring. The combination of these alleles determines traits, with some alleles being dominant and others recessive. This genetic inheritance follows Mendelian principles, where allele segregation and independent assortment play key roles.
Alleles are described as?
Different versions of a gene that can code for different traits. Alleles can be dominant or recessive, and individuals inherit two alleles for each gene, one from each parent. Variations in alleles contribute to genetic diversity within a population.
What name is given to different forms of same gene?
Alleles are different forms of the same gene, each producing a unique variation of a specific trait. Alleles can be dominant or recessive, and individuals inherit two alleles for each gene, one from each parent.
How come there are no carriers in genetic diseases caused by dominant alleles?
If carried on a dominant allele, you either inherit it- and have the disease- or you don't- and do not have the disease, nor the gene that causes it. If you don't have the gene, you can not pass it to your offspring.
Why does an organism have one factor for a dominant trait and one factor for a recessive trait?
Organisms have two factors (alleles) for a trait because they inherit one from each parent. Dominant traits are expressed when at least one dominant allele is present, while recessive traits are only expressed when both alleles are recessive. This is known as Mendelian inheritance.
Describes a trait or an allele that is expressed only when two of the alleles for the saame characteristic are inherited?
A trait or allele that is only expressed when two alleles of the same type are inherited is called recessive. This means that the individual must inherit two copies of the recessive allele to exhibit the trait. If an individual inherits one dominant allele and one recessive allele for a trait, the dominant allele will be expressed.
Different forms of a gene?
the alternative form of a gene is called an "allele."
