actually, they are not controlled by genes, but actually chromosomes. and they are NOT controlled by the same chromosome, unless you are an albino, in which case, a chromosome would take care of multiple genes.
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.
Traits controlled by a gene with multiple alleles can vary in terms of expression or phenotype. For example, human blood type (A, B, AB, O) is controlled by a gene with multiple alleles. The different alleles can result in different phenotypes (A, B, AB, O) for the same trait.
A dominant gene or variant, refers to gene alleles ("variants") that "beat" other (recessive) genes. Meaning that if an individual has both a dominant and a recessive allele for a certain trait, the dominant allele will express itself "over" the recessive one, affecting the phenotype accordingly. A common example, while being a simplification of the actual complexities of the matter, is hair color. Brown hair is dominant over blond hair. A person with blond hair has both genes for that trait recessive, while a person with brown hair can have either both "brown hair color" genes or one "brown hair color" gene plus one "blond hair color" gene.
An allele is a gene. It is one form of a gene. For example, height in pea plants is controlled by one gene with two forms. A pea plant can be tall or short. There is a short allele and a tall allele for the gene governing height.
Dominant Gene
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.
Yes, red hair is typically considered a recessive genetic trait. In order for a person to have red hair, they must inherit two copies of the recessive gene associated with red hair color from both parents.
Dominance in genetic terms is the tendency of one version of a gene to be expressed over another version of the same gene in the same organism. An example of this is hair on the fingers of humans, between the knuckle and the first finger joint. Having hair is dominant - if one of the two alleles in your genome says "grow hair", you will have hair on this portion of your skin. The only way you have no hair on this portion of your skin is for you to have two copies of the recessive gene (no hair).
:) it depends how mush cordination you have.
Teeth do not belong because they are not made of the same protein (keratin) as skin, hair, and nails.
Traits controlled by a gene with multiple alleles can vary in terms of expression or phenotype. For example, human blood type (A, B, AB, O) is controlled by a gene with multiple alleles. The different alleles can result in different phenotypes (A, B, AB, O) for the same trait.
It's the same than the difference between the hair of a turtle and a snake.
No, hair and nails are not the same. Hair is made of protein called keratin, while nails are also made of keratin but have a different structure and function in the body. Hair grows from follicles in the skin, while nails grow from the nail matrix at the base of the nail.
LL and Ll will both express the dominant gene, in this case short hair. Only an animal with both recessive genes (ll) will have long hair.
Yes, they can have a baby with blond hair if the mother has the gene that produces blonde hair (recessive) and also if the father has the same gene. It would be best if they both had blonde hair, but two people with brown hair can still have a blonde haired baby. It all depends on the genes that the parents received from their parents.
A dominant gene or variant, refers to gene alleles ("variants") that "beat" other (recessive) genes.

A person with blond hair has both genes for that trait recessive, while a person with brown hair can have either both "brown hair color" genes or one "brown hair color" gene plus one "blond hair color" gene.
Each and every person has the same set of genes - about 20,000 in all. The differences between people come from slight variations in these genes. For example, a person with red hair doesn't have the "red hair gene" while a person with brown hair has the "brown hair gene." Instead, all people have genes for hair color, and different versions of these genes dictate whether someone will be a redhead or a brunette.
