Is an organism that is homozygous for many recessive traits at a disadvantage?
It depends on the trait. A dominate trait is not always an advantage, and a recessive trait is not always at a disadvantage.
How many phenotypes can come from a heterozygous parent and a homozygous recessive parent?
Two types: A heterozygous parent (Aa) and a homoygous recessive parent (aa) can produce phenotypically dominate and phenotpically recessive offspring (with 50% genotypes Aa and the other 50% aa). If the genes are co-dominate then the offspring can have blended traits and recessive traits phenotypically.
Do traits vary from person to person?
Yes! Many types of people can have many different traits. There are people who have similar traits, but not everyone can have the exact same set of personality or physical traits.
Why do recessive trail are more common in some cases?
They're not necessarily, but they can be. When a recessive trait is more common, it likely because it was advantageous to have that trait so the species evolved to have more of it in the gene pool. Also, since dominant traits are expressed over recessive traits, natural selection has more of an effect on them.
Why did mendel perfrom so many crosses for the same characteristics?
The first few showed the dominant characteristics, but after so many crosses, the recessive traits began to show.
Albinism is a recessive trait in humans that is controlled by a single gene how many recessive alleles must a person have to have albinism?

How many recessive alleles must a person have to have albinism?

What factor controls a trait?
A person's genes are what control what traits. Genes can either be recessive or dominant and the combination of many different genes are what make up different traits.
Are many undesirable traits in humans recessive?
the term recessive traits referrs to genetics there are no bad traits recessive traits are the ones that are less likely to show up such as lleft handedness dominate traits are things like eye color,the color of your hair and skin etc
Traits determined by recessive genes located on the x chromosomes are said to be?
Some traits are determined by recessive genes on the X chromosomes. Many times these are genetic disorders and are called recessive genes.
What is the controller of traits of an organism?
The traits an organism displays is a result of their genetics. Recessive traits tend to not show in many organisms.

How does albinism affect the lifestyle of a person who has it?
People with albinism have many limitations. These limitations include burning easily in the sun and have extremely sensitive eyes.
How many phenotypes can come from a heterozygous parent and a homozygous recessive parent?
Two types: A heterozygous parent (Aa) and a homoygous recessive parent (aa) can produce phenotypically dominate and phenotpically recessive offspring (with 50% genotypes Aa and the other 50% aa). If the genes are co-dominate then the offspring can have blended traits and recessive traits phenotypically.
Is it possible to stop albinism?
No. Albinism is in a person's genetics and you can't stop a person from having it, or change someone who already has it. There are, however, surgeries that albino people have to option of having to make life easier as someone with albinism as many of the have eye problems and increased sensitivity to sun.
The trait of an organism is controlled by what?
The traits an organism displays is a result of their genetics. Recessive traits tend to not show in many organisms.
