yes, if two Bb parents have kids, there is a 3:1 ratio that their children will show a dominant trait (BB Bb Bb bb). For multiple alleles (3 or more) it gets a little more complicated. Some traits, like height, have 1000's of genes affecting them. Consult your Biology teacher for more information.
Yes. Because to have a dominant trait you can have two dominant alleles or just one dominant and one recessive (because a dominant allele negates the effect of a recessive allele.) To get a recessive trait it takes two recessive alleles as oppose to a dominant trait where it takes only 1 to have a dominant trait. Therefore Dominant traits are more common.

∙ 13y agoAnything dominant, really. You can use a punnett square to figure it out as well. Some examples of dominant traits in humans are brown eyes, brown hair, and detached earlobes. all the others that contrast to that would be recessive.
hope its helpful!

∙ 14y agoIn biology, the dominant alleles are usually expressed in the organism like brown eyes. the traits are then known as the phenotype of the organism.

If an offspring receives a pair of trait-controllers containing both a dominant and a recessive trait what happens to the recessive trait?
The dominant trait is shown in that organism with the possibility of carrying either the dominant or recessive gene to the next generation
A living thing with a dominant and recessive gene for a trait?
A living thing with a dominant and a recessive gene for a trait is heterozygous. This individual will display the dominant phenotype for that trait but may have offspring that display the recessive trait.
What gene is defined as a gene that controls the appearance of a certain trait?
the dominant allele
What is an XO genotype?
it means it has one gene from the dominant trait and one gene from the recessive trait
What is a dominant form of a kind of characteristic carried by a gene?
trait
Will a A trait controlled by a dominant gene be expressed even if the instructions of the corresponding gene in the other half of the pair are different?
Yes, a trait controlled by a dominant gene will be expressed even if the instructions of the corresponding gene in the other half of the pair are different.
What are non-mendelian trait?
Non-Mendelian traits are:A trait with no clearly dominant alleleA trait with four allelesA trait controlled by many genes
Dominant gene plus Dominant gene?
It would be definite that you have that gene or trait.
If an offspring receives a pair of trait-controllers containing both a dominant and a recessive trait what happens to the recessive trait?
The dominant trait is shown in that organism with the possibility of carrying either the dominant or recessive gene to the next generation
Organisms that are homozygous dominant and those that are for a trait controlled by simple dominance have the same phenotype?
Because the dominant gene always appears in the phenotype, whether or not it is "pure" (homozygous) or "mixed" (heterozygous). The recessive gene does what it says: it is recessive to the dominant gene. So, if it comes between the two, the dominant always appears. Of course, this only happens in your average Dominant-Recessive traits.
A living thing with a dominant and recessive gene for a trait?
A living thing with a dominant and a recessive gene for a trait is heterozygous. This individual will display the dominant phenotype for that trait but may have offspring that display the recessive trait.
What is a dominate trait?
Dominant trait is a genetics term. A dominant trait is one which will be expressed if one of the parents has the gene for that trait. A recessive trait is one that will be expressed only if both parents carry the trait.
What is it called when a trait that is not seen when a dominant gene is paired with a recessive gene?
Heterozygous dominant. Could also be called a masked trait.
WHAT is single gene trait?
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
When mendel crossed a strain of tall pea plants with a strain of short pea plants he observed that all the f1 generation were tall this suggest that?
the tall trait was controlled by a dominant factor.
What is an autosomal dominant trait?
When the gene is dominant and the traits are autosomal.
What is a gene trait?
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
