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.
What else can I help you with?
What is a trait controlled by only one gene?
How nice you are. Yeah I was shocked too when I found out.
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
What gene is defined as a gene that controls the appearance of a certain trait?
The gene defined as controlling the appearance of a specific trait is referred to as the "gene for that trait" or "trait-specific gene." These genes can influence physical characteristics like eye color, height, or leaf shape.
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.
A widows peak is a humans trait that is controlled by?
A widow's peak is a V-shaped point of hair at the front of the head, and it is controlled by genetics. It is inherited as a dominant trait, meaning one copy of the gene from either parent can result in a widow's peak.
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, if a trait is controlled by a dominant gene, it will be expressed regardless of the instructions of the corresponding gene in the other half of the pair. Dominant genes only require one copy to be expressed in the phenotype.
What is a trait controlled by only one gene?
How nice you are. Yeah I was shocked too when I found out.
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
Dominant gene plus Dominant gene?
It would be definite that you have that gene or trait.
Why did Mendel get when he crossed a tall and short pea plant?
Mendel obtained all tall plants in the first generation, showing that the tall trait is dominant over the short trait. This suggests that the tall trait is controlled by a dominant gene while the short trait is controlled by a recessive gene.
Which is a mendelian trait?
A trait controlled by many genes
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.
What is a trait that is expressed even if only one gene for that form of the trait is inherited?
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.
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 gene won't display its trait in the prescience of a dominate trait?
A recessive gene will not display its trait in the presence of a dominant trait. A recessive gene only expresses its trait when paired with another copy of the same recessive gene.
What gene is defined as a gene that controls the appearance of a certain trait?
The gene defined as controlling the appearance of a specific trait is referred to as the "gene for that trait" or "trait-specific gene." These genes can influence physical characteristics like eye color, height, or leaf shape.
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.
