The definition of homozygous is when a cell hastwo identical copies of a gene. An example of homozygous isa cell containing blue eye genes from both parents..
In this way, what is heterozygous for kids?
heterozygous. Genes come in pairs, calledalleles, and each pair is located in a specific position (or locus)on a chromosome. If the two alleles at a locus are identical toeach other, they are homozygous; if they are different from oneanother, they are heterozygous.
Beside above, what is heterozygous trait? An organism that is heterozygous for atrait has two different alleles for that trait. Sinceorganisms have two alleles for each trait, when the allelesof a pair are heterozygous (Yy), the dominant alleletrait is expressed and the recessive allele trait ismasked.
Correspondingly, what is a dominant gene for kids?
Remember that alleles are differing copies of the samegene. We also learned that copies of genes that arealways expressed, or used to make traits, over other alleles arecalled dominant, while the copies of genes thataren't expressed if a dominant allele is around are calledrecessive.
What is an example of a dominant trait?
Examples of Dominant Traits Dark hair is dominant over blonde or red hair.Curly hair is dominant over straight hair. Baldness is adominant trait. Having a widow's peak (a V-shaped hairline)is dominant over having a straight hairline. Freckles, cleftchin and dimples are all examples of a dominanttrait.

What is a dominant allele simple definition?
n an allele that produces the same phenotypewhether its paired allele is identical or different.Synonyms: dominant Type of: allele, allelomorph.(genetics) either of a pair (or series) of alternative forms of agene that can occupy the same locus on a particularchromosome and that control the same character.Is xy homozygous or heterozygous?
Females (XX) have two copies of each gene on the Xchromosome, so they can be heterozygous or homozygousfor a given allele. However, males (XY) will express all thealleles present on the single X chromosome that they receive fromtheir mother, and concepts such as 'dominant' or 'recessive' areirrelevant.Are humans heterozygous?
Homozygous and Heterozygous Since humans possess two copies of eachchromosome, they also have two copies of each gene and locus onthose chromosomes. Each of these trait-encoding genes (or loci) iscalled an allele. If the alleles are different, the person isheterozygous for that trait.Are the parents homozygous or heterozygous?
An organism can be homozygous dominant, if itcarries two copies of the same dominant allele, orhomozygous recessive, if it carries two copies of the samerecessive allele. Heterozygous means that an organism hastwo different alleles of a gene.How do you know if something is heterozygous or homozygous?
Genotypes, unlike phenotypes, can be homozygousor heterozygous. If an organism isheterozygous for a gene, or possesses one of each allele,then the dominant trait is expressed. A recessive allele is onlyexpressed if an organism is homozygous for thattrait, or posses two recessive alleles.What is a sentence for heterozygous?
having two genes that are different, with one beingrecessive and one being dominant. Examples of Heterozygousin a sentence. 1. Heterozygous eye color alleles ledthe boy to look like his brown-eyed mother but not his blue-eyedfather. ??What is difference between allele and gene?
Alleles are also genetic sequences, andthey too code for the transmission of traits. The short answer isthat an allele is a variant form of a gene. Explainedin greater detail, each gene resides at a specific locus(location on a chromosome) in two copies, one copy of thegene inherited from each parent.What happens when two homozygous plants are crossed?
Homozygous Versus Heterozygous A monohybrid cross between a parent that ishomozygous dominant and a parent that is homozygousrecessive for a particular trait produces offspring that are allheterozygous for that trait. These individuals have twodifferent alleles for that trait.What do you mean by allele?
allele. An allele is a variant form of agene. Some genes have a variety of different forms, which arelocated at the same position, or genetic locus, on a chromosome.Humans are called diploid organisms because they have twoalleles at each genetic locus, with one alleleinherited from each parent.Are freckles homozygous recessive?
Homozygous Freckles Having freckles is a third example of a dominanttrait. Let's also assume that both Sally and John have one dominantallele for freckles and one recessive allele. Sallyand John would both have a heterozygous genotype forfreckles, which would be represented as"Ff."What homozygous dominant genotype?
A homozygous dominant genotype is one in whichboth alleles are dominant. For example, in pea plants,height is governed by a single gene with two alleles, in which thetall allele (T) is dominant and the short allele (t) isrecessive.
