Why is an organism genotype may be homozygous dominant homozygous recessive or heterozygous but never heterozygous recessive?
I take it you're referring to the phenotype. Say a trait, like flower colour, is influenced by a single gene. The plant will possess two copies of the gene, one from each parent, but only one colour is expressed. Let's say that red is dominant and white is recessive. A plant containing 2 red alleles (homozygous for the dominant allele) will be red. A plant containing 2 copies of the white allele (Homozygous recessive) will be white and heterozygous plant, containing a single copy of both alleles will be red. There is no heterozygous recessive because the dominant allele will determine the phenotype.
If Genotype of a G as dominate green and g for recessive yellow what would the heterozygous look like?
the heterozygous will look like green because the green is dominant allele.
What is the difference between homozgous and heterozygous?
Heterozygous vs. Homozygous: These terms refer to genetic mutations. There are two copies of the protein codes in the genetic code. If one copy is normal and the other has the mutation, it is said to be heterozygous. If both copies have the mutation, it is said to be homozygous. For example: A/A -- homozygous. A/a -- heterozygous. a/A -- heterozygous. a/a -- homozygous.Homologous refers to the pair of chromosomes that are the same whilst Homozygous refers to the fact that alleles of a gene pair are the same
What is heterozygous?
Heterozygous refers to alleles that are not the same. For example, lets pretend that the gene for hair color is H for brown hair and h for blond hair. If someone was HH, they would be homozygous because the two alleles of the gene are the same. If a person was blond, their genes would have to be hh, which is homozygous recessive. Heterozygous is when the alleles are different, like so: Hh.
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.

How does heterozygous and homozygous differ?
Heterozygous is when you are a hybrid, and you have one recessive and one dominant allele. Like Aa for example. people who are homozygous are either homozygous dominant or homozygous recessive. Homozygous recessive is when you have two recessive alleles, like aa. Homozygous dominant you could either have Aa or AA. A capital letter represents the dominant allele, and a lower case letter represents the recessive allele. If one of your parents had brown eyes, and one had green, and the brown is dominant and the green is recessive, and you were heterozygous, you would have brown eyes. E (lets just say stands for eyes) would be dominant and e would be recessive. if you were heterozygous, you would have Ee. You'd have brown eyes because the dominant allele masks the recessive allele. and yes im only 13 years old im sorry if its too confusing i probably didnt word it right:)
If Genotype of a G as dominate green and g for recessive yellow what would the heterozygous look like?
the heterozygous will look like green because the green is dominant allele.
What can you predict about the offspring if you know the genotypes of the parents?
So, if one parent is Aa (heterozygous) and the other parent is aa (homozygous recessive) the punnett square would look like this: ___|_A__|__a_ _a_|_Aa_|_aa_ _a_|_Aa_|_aa_ The genotypes of the offspring 50% heterozygous and 50% homozygous recessive
What kind of alleles does a heterozygous individual have?
2, it means that both of the alleles are different when compared to homozygous. Homozygous alleles are like aa or AA. Heterozygous simply means Aa so it has one dominant and one recessive allele

If one copy is normal and the other has the mutation, it is said to be heterozygous. If both copies have the mutation, it is said to be homozygous. For example: A/A -- homozygous.

What is the difference between a homozygous individual and a heterozygous individual?
In genetics, homozygous genes are identical alleles, while heterozygous genes have different alleles. For example, TT(same alleles) is homozygous genotype, while Tt (different alleles) is a heterozygous genotype.
Condition of being heterozygous for a recessive trait?
If you are heterozygous this means you carry both a dominant and recessive allele. if you are heterozygous for a recessive trait then you will have a dominant and recessive allele. example: let T represent tall and t represent short. a person with heterozygous for a recessive trait will have 'Tt'.
Is heterozygous Bb or BB?
It's heterozygous. Heterozygous is when there is a big letter and a little letter, like Bb. Homozygous is when both letters are the same size, like BB or bb.
Can several alleles affect a single trait like eye color?
Alleles affect traits like eye color. Alleles for brown and blue eyes are dominant and recessive respectively. Individuals who have homozygous and heterozygous genotypes with the dominant allele will have brown eyes. However individuals are homozygous for the recessive allele will have blue eyes.
What is heterozygous?
Heterozygous refers to alleles that are not the same. For example, lets pretend that the gene for hair color is H for brown hair and h for blond hair. If someone was HH, they would be homozygous because the two alleles of the gene are the same. If a person was blond, their genes would have to be hh, which is homozygous recessive. Heterozygous is when the alleles are different, like so: Hh.
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.
