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 is the combination of genes important in determining the inheritance of biological traits?
The genes an organism contains is called the organism's genotype.
What is a genotype composed of?
Genotype is the genetic make up of an organism both expressed (phenotype) and unexpressed.Example: AaeeDndn is the genotype which includes unexpressed (recessive) alleles a and dn.Expressed dominant traits A and Dn as well as expressed recessive traits (ee). Note that expressed recessive traits have to be homozygous.
In the F2 generation in Mendel's experiment's the ratio of dominant to recessive traits was?
3:1 homozygous dominant, heterozygous dominant, heterozygous dominant and homozygous recessive.
Are recessive traits are always shown in an organism offspring?
No, a recessive trait will only show in the offspring if there is no dominant allele masking it. The trait that will always show in the offspring is the dominant allele, provided one parent was homozygous for it.
Are Recessive traits always shown in an organism's offspring?
No, a recessive trait will only show in the offspring if there is no dominant allele masking it. The trait that will always show in the offspring is the dominant allele, provided one parent was homozygous for it.

What are the types of homozygous traits you can get from punnet squares?
AA: Homozygous dominant aa: Homozygous recessive
What is the phenotype of a purebred recessive?
A recessive trait is known as the characteristic that is the outward expression of the gene. Recessive traits can be masked by dominant traits but are still present if the gene is present in the organism.

Genotype is the genetic make up of an organism both expressed (phenotype) and unexpressed.Example: AaeeDndn is the genotype which includes unexpressed (recessive) alleles a and dn.Expressed dominant traits A and Dn as well as expressed recessive traits (ee). Note that expressed recessive traits have to be homozygous.
Why is it not necessary when the dominant and recessive traits are known to use the term homozygous when referring to the genotype of an individual that has a recessive phenotype?
An organism with a recessive allele from a particular form of a trait will exhibit that form only when the dominant allele for the trait is not present.
When will a recessive trait show its effect?
A recessive trait will be expressed when there is no dominant allele in the genotype for that trait. In a Mendelian trait, where one gene with one dominant and one recessive allele governs a trait, a recessive trait will be expressed when the individual's genotype for that trait is homozygous recessive, meaning that both of the individual's alleles for that trait are recessive.
In the F2 generation in Mendel's experiment's the ratio of dominant to recessive traits was?
3:1 homozygous dominant, heterozygous dominant, heterozygous dominant and homozygous recessive.
Are Recessive traits always shown in an organism's offspring?
No, a recessive trait will only show in the offspring if there is no dominant allele masking it. The trait that will always show in the offspring is the dominant allele, provided one parent was homozygous for it.

No, a recessive trait will only show in the offspring if there is no dominant allele masking it. The trait that will always show in the offspring is the dominant allele, provided one parent was homozygous for it.
What do you call traits that can only be seen if the individual has both alleles for it?
Homozygous recessive.
What is the difference between homzyguos and heterozyous?
Homozygous recessive: is when the genes are both recessive Homozygous dominant: is when the genes are both dominant (traits show) Heterozygous dominant: is when one gene is dominant and one is recessive (traits show) Heterozygous recessive: is the same as heterozygous dominant but the dominant genes are inactive
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.
