Two fruit flies having the same red eye color is an example of two organisms that are homozygous for the eye color trait. If the fruit flies had different eye colors, then they would be heterozygous for the trait.

What is when an individual has two copies of a dominant allele?
The person is considered to be heterozygous dominant. Heterozygous refers to having to of the same allele (AA or AA). dominant means AA not AA
Organisms that has two different alleles for a trait?
Having two different alleles for a trait is called heterozygous.
Which term means the state of having two different alleles for the same trait?
Two different alleles for the same trait are heterozygous. No, Its homozygous. This answer is incorrect as homo = same.
Organisms that have identical alleles for a particular trait are called?
There is no particular relationship between organisms that have identical alleles for a particular trait.
What is homozygous recessive genotype?
variation in alleles of genes, occurs both within and among populations. Genetic variation is important because it provides the genetic material for natural selection. Genetic variation is brought about by mutation, which is a permanent change in the chemical structure of a gene. Polyploidy is an example of chromosomal mutation. Polyploidy is a condition wherein organisms have three or more sets of genetic variation (3n or more).
What does heterozgous mean?
Heterozygous is to different alleles and homozygous is having the same alleles.
What do homozomes and heterozygous mean?
In genetics, you have certain traits that give you certain features. You get one part from each parent. You may have a dad with brown eyes and a mom with blue. Your dad maybe BB or Bb, and your mom bb. Like in eye color, there's brown, blue, hazel, and other colored eyes. Brown eyes is a dominant trait. So it is homozygous dominant or heterozygous (homozygous dominant = BB, heterozygous = Bb). Blue eyes are a recessive trait (homozygous recessive = bb). So, homozygous are carrying one single part of the trait, and heterozygous is carring a part of both traits.
What is Having two unlike genes for the same trait?
When two alleles differ from each other, such as Tt, it is called heterozygous, hetero meaning different. When alleles are the same (TT) it is called homozygous, homo meaning same.
What do you call an organism that possesses two dominant or two recessive genes fir a single trait?
I think you are referring to the term homozygous. This term applies not to the entire organism but is typically used with regard to one trait. For example, homozygous tall or homozygous dwarf when referring to height in peas. The term heterozygous refers to having one dominant and one recessive gene, or at least to having two different forms of the gene.
What is the genotype and phenotype of homozygous?
Are you talking about phenotype or genotype? Phenotype is the expression of the genotype. Genotype is what you inherited. Phenotype is what you see. Homozygous is the same. Heterozygous is different. If you inherit one allele for blue eyes and one allele for brown eyes, your phenotype should be brown eyes. Your genotype would be brown eyes, blue eyes. You would have a heterozygous genotype.
What is when an individual has two copies of a dominant allele?
The person is considered to be heterozygous dominant. Heterozygous refers to having to of the same allele (AA or AA). dominant means AA not AA
When two homozygotes for same allele are crossed what happens?
If you are looking to see what happens to a specific trait, this is not actually an answerable question in this context. It is so open-ended. Also, parents are not directly homozygous or heterozygous, the genes are. However, in the simplest case, half of the offspring would be homozygous for the gene in question and half would be heterozygous. How this affects the phenotypic trait under observation depends on a lot of other things.
Why can the father not be homozygous for a dominant trait?
Homozygousity is defined as having the two alleles that are the same for a certain locus. For example, AA or AA are both homozygous. Dominance, however, is a different concept and it is independent of homozygousity. In addition, both dominance and homozygousity are independent of the sex of the individual (unless the trait is X-linked) Therefore, the three possibilities of homozygous dominant, heterozygous, and homozygous recessive for a trait are available for a male just as a female individual.
Do a punnett square for one parent having AAA and the other having AAA?
For the two given parents: 1 offspring will have the homozygous genotype: YY 1 offspring will have the homozygous genotype: yy 2 offspring will have the heterozygous genotype: Yy
An individual heterozygous for a trait and an individual homozygous recessive for the trait are crossed and produce many offspring?
The offspring has a 50% chance of the dominate trait (while being heteroygous) and a 50% chance of having the recessive trait ( homozygous recessive).
An organism is called a homozygote if it carries two different alleles?
If both alleles are the same, the organism is homozygous for the trait. ... If one allele is missing, it is hemizygous, and if both alleles are missing, ... An organism is heterozygous
Why do children have characteristics of both their mother and father?
Children have similar characteristic's to their parents because when they are conceived, both of the parents genes unify to create a new set of characteristic'd depending on dominant and recessive traits. For example, Jane and Henry find out they are having a baby. Jane has homozygous blue eyes whilst Henry has heterozygous brown eyes. The chances are that their baby will either have 50% homozygous blue eyes or 50% heterozygous brown eyes.
