Dominant alleles are expressed regardless of any other alleles. Recessive alleles are not expressed if a dominant allele is present.
Dominant alleles are written with capital letters (eg. B or T), recessive with lower case letters (eg. b or t).
Dominant - if B codes for black fur - BB and Bb will both end up with black fur.
Recessive - if b codes for white fur, only bb will result in white fur.
The difference between a dominant allele and a recessive allele is that if a person inherits one dominant allele and one recessive allele the dominant allele will appear as it is stronger or more dominant than a recessive allele the dominant allele is stronger the recessive allele weaker. For instance brown eyes is a dominant allele, blue eyes is a recessive allele.
A recessive allele does not always determine the trait.
Dominant alleles override recessive alleles. For instance, if there is both a dominant allele and a recessive allele present the dominant allele will be the trait that you end up with. If you have two recessive alleles, then you will have the recessive trait. :::::::::::::::brown eyes overrided blue eyes, because they are darker:::::::::::::::::: usually a darker color overpowered/override the lighter ones....i dont really know why but my science teacher said so......
"Heterozygous" and "homozygous" are terms that refer to alleles, which, in genetics determine what trait, from which parent, will appear in the offspring. Alleles can be either Dominant or Recessive. Every organism has two alleles, which can both be dominant, both recessive, or one of each.So,If an organism heterozygous, it has one recessive and one dominant allele.If an organism is homozygous then both of its alleles are the same; you need to specify if they are homozygous recessive (both alleles are recessive) or homozygous dominant (both alleles are dominant).
Genotype refers to the genetic makeup of an organism, including both the dominant and recessive alleles present. Phenotype, on the other hand, is the physical expression of those genetic traits, which can be influenced by both dominant and recessive alleles. The genotype determines the phenotype, with dominant alleles more likely to be expressed in the phenotype than recessive alleles.
Homozygosity refers to having two identical alleles for a particular gene (e.g., both alleles are dominant or both are recessive), while heterozygosity refers to having two different alleles for the same gene (one dominant and one recessive allele). In homozygosity, an individual's genotype is either homozygous dominant or homozygous recessive, whereas in heterozygosity, the genotype is a combination of both dominant and recessive alleles.
Homozygous individuals have two identical alleles for a particular gene, while heterozygous individuals have two different alleles for the same gene. Homozygotes can be either homozygous dominant (two dominant alleles) or homozygous recessive (two recessive alleles), while heterozygotes have one dominant and one recessive allele.
Dominant alleles override recessive alleles. For instance, if there is both a dominant allele and a recessive allele present the dominant allele will be the trait that you end up with. If you have two recessive alleles, then you will have the recessive trait. :::::::::::::::brown eyes overrided blue eyes, because they are darker:::::::::::::::::: usually a darker color overpowered/override the lighter ones....i dont really know why but my science teacher said so......

the dominant trait is the stronger one and the recessive trait is the weaker one

An individual must have 2 recessive alleles in order for a trait to show up. One must only have 1 dominant allele in order for a trait to occur.
Homozygosity refers to having two identical alleles for a particular gene (e.g., both alleles are dominant or both are recessive), while heterozygosity refers to having two different alleles for the same gene (one dominant and one recessive allele). In homozygosity, an individual's genotype is either homozygous dominant or homozygous recessive, whereas in heterozygosity, the genotype is a combination of both dominant and recessive alleles.
This inter action is called dominance .
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
Homozygous refers to having two identical alleles for a particular gene (e.g., two alleles for blue eyes). Heterozygous refers to having two different alleles for the same gene (e.g., one allele for blue eyes and one allele for brown eyes).
A Punnett square is a genetics tool that uses letters to represent dominant and recessive alleles. This tool is used to predict the possible outcomes of a genetic cross between two individuals.
There are no such things as dominant and recessive genes. There are only dominant and recessive alleles. Dominant alleles are parts of a gene that present its features over the recessive allele, which is the one that is always masked by the dominant allele. The recessive allele's trait only shows if both of the alleles in a trait are recessive.
Homozygous individuals have two identical alleles for a particular gene, while heterozygous individuals have two different alleles for the same gene. Homozygotes can be either homozygous dominant (two dominant alleles) or homozygous recessive (two recessive alleles), while heterozygotes have one dominant and one recessive allele.
