∙ 15y agoThere is no allele for short hair. Short hair is not a pheontype, it's a hair cut.

∙ 13y agothere is actually no allele for black hair unless you dye it black your baby might come out with dyed black hair also there is only an allele for brown,red,and blond hair

How do you write alleles?
It will be the lowercase form of the dominant allele. For example the dominant form for tallness is T, the recessive allele for shortness is t.
What stands for dominant allele?
Normally a dominant allele is represented by a capital letter. It can be any letter used. Example; Brown hair is dominant and blond is recessive. B represents the dominant allele (brown) and b represents the recessive (blond) in Bb. You can have any combination of two alleles; BB, Bb, or bb. BB would have brown hair, Bb would have brown hair or a mix, and bb would have blond hair. Instead of B we could have used T or any other letter.
What is an example of multiple allele heredity?
An allele is a type of gene that is hereditory. In fertilisation, an allele from both the father and mother are fused, this is multiple allele hereditory. Alleles influence many things, from hair colour to blood type. human blood typeshuman blood types
What does it mean to have a dominant trait?
In genetics, a trait is considered dominant when it determines a phenotype over a recessive trait. For example, AA is crossed with AA to make Aa, Aa, Aa, and Aa. If "A" is the dominant trait and "a" is the recessive trait, then since this cross produces heterozygous progeny, they will all show the dominant phenotype. A dominant trait is just how it sounds, it dominates over recessive traits when they are both present.
What is allele masked by the dominant allele?
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.
Wavy hair is caused by the shared expression of a allele for curly hair and an allele for straight hair?
it depends on which allele is most dominant in the parents.
What colour would a person's hair be if he or she inherited a brown hair allele and a black hair allele?
dark brownn
What does this tell you about the allele for white hair in horses?
The allele for white hair is recessive...study island
How Do recessive and dominant alleles get filled into a punnet square?
here is an example: key: dark hair - H (dominant) light hair - h (recessive) father: Hh mother: hh father's alleles: H & h mother's alleles: all h punnet square: father's __H____l____h_____ Mothers: h l Hh l hh The father's dominant H allele combines with the mother's h allele produces Hh The father's reccesive h allele combins with the mother's h allele produces hh therefore the possible combinations of alleles are Hh and hh. 1/2 of their children will have dark hair and 1/2 of their children will have light hair
If straight hair is genetic why do you have straight if none f your ancestors did?
it is because the parents each were heterozyous dominant. meaning each of them had a dominant allele and a recessive allele. the dominant allele would be the curly hair, and the recessive allele would be the straight hair. There would be a 1/4 chance that the child would have curly hair, and a 3/4 chance that they would have curly hair. Say that the Curly hair allele was H and the straight hair allele was h. In order for the parents to have curly hair, they would either have to have an HH gamete or an Hh gamete. Seeing as though the child came out with curley hair, both parents would have to have an Hh gamete. In order to find out the probability, you multiply the parents gametes. (Hh)(Hh). This will give you HH, Hh, Hh, hh. seeing has three of the gametes have the dominant allele, this child will have curly hair, and one is a homozygous recessive, so it will turn out with straight hair.
If Patrick has red hair and his parents have brown hair Patrick's trait must be?
one of his parents must have the red-hair allele, but they both have brown hair so they are both hetereozygous with the dominant brown allele. Patrick's red hair is homozygous recessive
Why do most people have brown hair?
It's all in the Genes. The dominant color gene allele for hair is brown.
What what is an example of a recessive allele?
blue eyes blonde hair etc.. brown eyes and brown hair are dominant
What the different between a dominant and recessive trait?
In simple Mendelian genetics, there may be several alleles (variations) for a given trait. since organisms generally have two pairs of chromosomes, they have two alleles. A dominant allele is one that when it is present, always shows itself. A recessive allele only shows when there are two copies of the recessive allele. For example, suppose brown hair is dominant and black hair is recessive. If there are any copies of the brown hair allele, the person's hair will be brown. A person's hair will be black only if they have two copies of the black hair allele. In reality, genetics is much more complicated than simply dominant and recessive as many genes may influence one trait.
How do you write alleles?
It will be the lowercase form of the dominant allele. For example the dominant form for tallness is T, the recessive allele for shortness is t.
What does it mean to have brown hair?
Doesnt "mean" anything. If someone has brown hair the dominant Allele between the two parents happened to be brown hair...
If a child has blonde hair and both the parents have brown hair what does that tell you about the allele for blonde hair?
It tells you that even though the parents have brown hair, they have a recessive allele for blonde hair also. And even though brown is suppose to be visually dominant, it is not the case at all. Two brown heads can make a blonde or brown, and of course even red haired child. Another way to look at it may be the parents have the following alleles for hair color: (b,b) - (b,b) in which case the dominant allele is Blonde or Brown.
