a homozygous trait is when an offspring has either both dominant genes or both recessive genes from its parents. a heterozygous trait is when an offspring has both dominant and recessive genes. for example: a long-tailed cat is dominant and a short-tailed cat is recessive. the long-tailed cat (homozygous dominant) had offsprings with the short-tailed cat (homozygous recessive). by doing the punnett square, 100% of their offspring will be heterozygous.
Heterozygous is when the organism has two different alleles for a traitHomozygous is when they have two of the same the sameexample of homozygous= two blue eyesexample of heterozygous= one blue eye and one green eyeHomozygous is when the combination of alleles are the same. EX: AA or BB. Heterozygous are when the combination of alleles are different. EX: Aa or Bb.
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
Heterozygous is a combination, for example two different alleles, as opposed to homozygous, for example two identical alleles.
A trait that exhibits incomplete dominance, is one in which the heterozygous offspring will have a phenotype that is a blend between the two parent organisms. An example of this is when a homozygous red sweet pea flower crossed with a homozygous white sweet pea flower, their offspring will be heterozygous and have the pink phenotype, rather than either red or white. So, the homozygous red flower will be red, the homozygous white flower will be white, and the heterozygous flower will be pink. So there are three possible phenotypes in incomplete dominance. There are also no dominant or recessives genotypes.
it means there is one of each. in a homozygous gene it means that there are two of the same. for example if "t" repressents a recessive trait and "T" represents a dominant trait, then an organism with a gene that is tT would be considered heterozygous, and a gene that is TT or tt would be considered homozygous or "pure bred"

it's to do with genes, a homozygous organism has two alleles that are the same, whereas a heterozygous organism will have two different alleles. eg, on a chromosome for eye colour, a homozygous example would have both alleles for say, blue eyes. a heterozygous example would have an allele for blue and an allele for brown, where brown would be dominant, reccesive, or cooperative.
You're looking at a gene which contains 2 alleles (meaning variations of that gene). Let's call it "A."Remember that you get 2 copies of EACH gene (one from mom, one from dad).

You can't have heterozygous dominant or recessive. A genotype is either homozygous dominant (MM), homozygous recessive (mm) or heterozygous (Mm). Hope it helps!
a heterozygous gene is a gene with a genotype with two different letters. For example, Hh rather then hh, HH (which are homozygous). Hope this helps. =)
Heterozygous is a combination, for example two different alleles, as opposed to homozygous, for example two identical alleles.
The possible genotypes of parents who are heterozygous would be found using a punnet square. The outcome would be 50 percent heterozygous dominant, 25 percent homozygous dominant, and 25 percent homozygous recessive.
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.
A trait that exhibits incomplete dominance, is one in which the heterozygous offspring will have a phenotype that is a blend between the two parent organisms. An example of this is when a homozygous red sweet pea flower crossed with a homozygous white sweet pea flower, their offspring will be heterozygous and have the pink phenotype, rather than either red or white.

The words homozygous and heterozygous don't apply to the chromosomes that you have but instead refer to the differing alleles (versions) of a gene you have. For example if you have a brown hair allele and a blond hair allele, you are said to be heterozygous for the hair colour gene. If you have two of the same allele you are said to be homozygous. As such one person will heterozygous for some of the thousands of human genes and homozygous for others. If you are XY it means you are male, and XX means you are female.
