Dominant - everything is dominant apart from diseases such as malaria, cystic fibrosis
Dominant alleles are the ones that show up in the phenotype. Recessive alleles do not unless both alleles are recessive, but can be passed on. For example: Tt , T=tall and t=short. Tall is dominant and short is recessive. You are tall and can pass on the short gene. Or, you can use black hair being dominant over red. Or, brown eyes being dominant over blue. Dominant can be seen on you and recessive can't.
When an offspring inherits a dominant gene from one parent and a recessive gene from the other, the dominant trait will typically be expressed in the offspring. This occurs because dominant alleles mask the effects of recessive alleles. For example, if the dominant gene is for brown eyes (B) and the recessive gene is for blue eyes (b), the offspring will have brown eyes (Bb) as the dominant trait prevails.
If by "all dominant phenotypes" you mean the parents are homozygous, then no. AA x AA will never yield a gamete with AA But if you're talking about heterozygous chromosomes Aa x Aa, then yes
You would use a capital letter. And for the recessive a lower case. For example. Brown hair is dominant over blonde. B for Brown (the dominant) And b for Blonde (the recessive)
dominant-appears in first generation recessive-seems to dissapear
Well, black hair is the most dominant, but if you were comparing, say, blond hair to brown hair then the brown hair would be dominant. I am studying this for collage right now so I an pretty sure this is right, if it's not i am so doomed :0!!! lol! hope that helped, Aquilo
Brown eyes are dominant. That's why more people have brown eyes then hazel or blue or green.
With brown eyes, they are recessive.
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.
A dominant trait is the trait that will show. A recessive trait is the trait that is hidden. For example if your mom had brown eyes and your dad has green eyes you would have brown eyes because brown eyes are the dominant trait
An allele that is masked by the dominant allele is called a recessive allele. When an individual has one dominant allele and one recessive allele, only the trait determined by the dominant allele will be expressed. The recessive allele will only be expressed if an individual has two copies of it (homozygous recessive).
Dominant alleles are the ones that show up in the phenotype. Recessive alleles do not unless both alleles are recessive, but can be passed on. For example: Tt , T=tall and t=short. Tall is dominant and short is recessive. You are tall and can pass on the short gene. Or, you can use black hair being dominant over red. Or, brown eyes being dominant over blue. Dominant can be seen on you and recessive can't.
Examples of dominant genes include brown eyes and attached earlobes, where the dominant allele will be expressed over its recessive counterpart. Recessive genes include blue eyes and detached earlobes, which will only be expressed when an individual has two copies of the recessive allele.
When an offspring inherits a dominant gene from one parent and a recessive gene from the other, the dominant trait will typically be expressed in the offspring. This occurs because dominant alleles mask the effects of recessive alleles. For example, if the dominant gene is for brown eyes (B) and the recessive gene is for blue eyes (b), the offspring will have brown eyes (Bb) as the dominant trait prevails.
Some traits are dominant and others are receptive. The gene for blue eyes is recessive and the gene for brown eyes is dominant.
Alleles can be dominant or recessive
Brown eye color is dominant, while blue, green, and hazel eye colors are recessive. This means that brown eyes are more likely to be expressed if an individual inherits one brown-eyed allele and one allele for a different eye color.
