what is the difference between.....?

Question

homozygous
and hetrozygous
brief answer please

Answer 1

homozygous-- genotype in which both alleles are the same

heterozygous-- genotype in which the alleles of a pair are different

Answer 2

A homozygote's cells are diploid or polyploid and have the same alleles at a locus (position) on homologous chromosomes. When an organism is referred to as being homozygous for a specific gene, it means that it carries two identical copies of that gene for a given trait on the two corresponding chromosomes (e.g., the genotype is AA or aa). Such a cell or such an organism is called a homozygote.

A homozygous dominant genotype occurs when a particular locus has two copies of the dominant allele (e.g., AA). A homozygous recessive genotype occurs when a particular locus has two copies of the recessive allele (e.g., aa). This can occur when both parents carry at least one copy of the allele.

Put simply: Homozygous is just having two of the same alleles.

An organism is a heterozygote or heterozygous for a gene or trait if it has different alleles at the gene's locus for each homologous chromosome. Such an organism must be either diploid, have two homologous chromosomes in each cell, or polyploid, having more than two homologous chromosomes. In diploid organisms, the two different alleles were inherited from the organism's two parents. These different alleles contain different genetic codes. One allele may override the other, or they may both be expressed in a trait simultaneously.

Heterozygosity refers to the state of being a heterozygote, but in population genetics, it commonly refers to the fraction of individuals in a population that are heterozygous for that locus. Heterozygosity can also refer to the fraction of loci within an individual that are heterozygous.

In a heterozygous individual, each allele produces its own unique protein or enzyme. The result is a mixture of the two rather than a combination of the two into one. If the presence of the abnormal enzyme produces an abnormal effect in the heterozygote, the abnormal allele is termed a dominant gene. In other cases, especially when the abnormal allele produces a nonfunctional enzyme, the abnormal enzyme molecules have no obvious effect on the heterozygote. The individual is an asymptomatic carrier of the abnormal allele, which is referred to as a recessive gene.

To symbolize how a gene is inherited (Main article: Mendelian inheritance), the dominant allele is indicated with an upper case character and the recessive with a lower case character. The colour of Mendel's peas are often indicated as PP for the dominant homozygote, which produces a pink flower, and pp for the recessive homozygote, which produces a white flower. When these are crossed, the F1 or first filial generation receives a chromosome with the P gene from the pink-flowered parent and a corresponding chromosome with the p gene from the white-flowered parent. All of the F1 generation are heterozygous, and this is indicated with Pp. All of the F1 plants produce pink flowers.

Some genes are neither dominant nor recessive to another allele. In such cases, both alleles affect the heterozygote. Sometimes the result is intermediary: when a red carnation is crossed with a white carnation, they produce heterozygous carnations with pink flowers. If the test is sensitive enough, the heterozygote has the phenotype of both parents: when a person who is homozygous for the A blood type gene marries a person who is homozygous for the B blood type gene, they produce heterozygous children who express both A and B antibodies (see, co-dominance).

Answer 3

Homozygous is when you have two identical alleles of a particular gene.
Hetrozygous is when yo have two different alleles of a particular gene.

Answer 4

" Homozygous - occurs when the two genes for a trait are the same.
Heterozygous - occurs when the two genes for a trait are different, also known as a hybrid."

Answer 5

homozygous is a gene with 2 dominant alleles or two recessive alleles and heterozygous is a gene with one dominant allele and one recessive allele

Answer 6

homozygous is a gay zygous and a hetrozygas is a zygous who like to look pretty which pretty much makes them the same.

Answer 7

Look in the back of your Biology book- under "definitions..."

Answer 8

homo=the same/alike

adn hetero=different types/kinds
