What does it mean that an organism is homozygous recessive for a trait?
That organism has two recessive alleles for that trait, one from each parent. It will display the recessive trait.
How does meiosis ensure that each reproductive cells cells only gets gets one gene for each trait?

A genetic trait expressed in a person who has only one copy of the gene associated with the trait?
Dominant
What is one difference between single gene trait and a polygenic trait?
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
What is a trait controlled by only one gene?
How nice you are. Yeah I was shocked too when I found out.

That organism has two recessive alleles for that trait, one from each parent. It will display the recessive trait.
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.

Will an offsping show a recessive trait if only one of its parents has the gene for that trait?
No
What is the difference between a single gene and a polygenics trait?
A polygenic trait is a trait in which multiple sets of alleles are used to determine the trait, whereas in a single gene trait aka. a Mendelian trait, only one pair of alleles is used.
A genetic trait expressed in a person who has only one copy of the gene associated with the trait?
Dominant
What shows that alleles might combine?
The manifestation of two traits or a whole new trait, whereas in examples where only each of the gene is present, the manifestation of one trait in either one.
Genes that are only seen when paired with a recessive gene?
if u have a recessive gene with a recessive gene then u can see the recessive gene but if you have a dominant gene with a recessive gene you can only see the dominant gene hope that helps:)
Can children get sickle cell?
Only if they have 2 parents with the trait(gene) or disease
What type of trait is only seen if its gene is present in both gametes that unite to start the life of a new organism?
Recessive trait.This trait is only manifested if gametes from both parents pass on the gene to the new organism
What is one difference between single gene trait and a polygenic trait?
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
What is a recessive traits?
An x-linked recessive trait is a trait located on a x gene that is not dominant. It typically will show up when there is only 1 x gene, in the instance of males. Color blindness is an example.
