What is the difference between heterozygous and homozygous alleles?

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).

∙ 14y agoHomozygous alleles are the same alleles. Either both dominant or both resessive. Example: AA or aa.
Heterozygous are both a dominant and recessive allele. Example: Aa

Show the cross between 2 heterozygous dogs. black fur B is dominant to brown fur b?
BbxBb = 25% homozygous BB; 50 % heterozygous Bb, and 25% homozygous recessive bb.
What does genotypic ratio mean?
genotype means genetic make up. it can give the information about the parents wether they were homozygous or heterzygousAnswer (Improved)A genotypic ratio is the proportion of genotypes found in individuals after a cross. For example, consider a cross between two heterozygous individuals for trait A: Aa X AaThe result is a 1:2:1 ratio for the genotypes AA, Aa, and AA respectively. Put another way, if the parents had 100 offspring, 25 would be expected to have the genotype AA, 50 the genotype Aa and 25 the genotype AA.This is hard Good Luck
How are dominant and recessive traits represented?
Autosomal recessive alleles ( both males and females) and X-linked alleles in females always express themselves in homozygous condition. On other hand, X -chromosome linked recessive allele express singly in males.
In aquirrelsblack fur is recessive to grar fur show the genotypic and phenotypic ratios of a cross between a heterozygous gray squirrel with a black squirrel?
they can not cross breed.
What does incomplete dominan ces mean?
This means that a trait which is expressed is between the dominant and recessive genes. This means both alleles are partially expressed.
What is the difference between a herezygous and a homozygous?
"Heterozygous" and "homozygous" are terms that refer to alleles, which, in genetics determine what trait, from which parent, will appear in the offspring. Alleles can be either Dominant or Recessive. Every organism has two alleles, which can both be dominant, both recessive, or one of each.So,If an organism heterozygous, it has one recessive and one dominant allele.If an organism is homozygous then both of its alleles are the same; you need to specify if they are homozygous recessive (both alleles are recessive) or homozygous dominant (both alleles are dominant).
1 What is the difference between homozygous and heterozygous?
Homozygous is the same(purbred) and heterozygous is different(hybrid)
Differentiate between homozygous and heterozygous?
Homozygous means that both alleles for a gene are the same, designated by two identical letters, such as RR (dominant) or rr (recessive). Heterozygous means that both alleles for a gene are different, designated by two different alleles, such as Rr.
What is the difference between a homozygous dominant homozygous recessive and heterozygous individual?
They are the same
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.
What is the difference between homozygous and 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.
The difference between homozygous and heterozygous?
one is curved one is straight
What is the difference between homozygous and heterozygous organism?
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.
What is the opposite of homozygous of dominant?
heterozygous recessive
What is the difference between purebred organism and a hybrid?
A purebred organism is the offspring of two homozygous parents, having either two dominant alleles, AA or two recessive alleles, aa. A hybrid is the offspring of two heterozygous parents, Aa.
Diffrence between homozygous and heterozygous?
They refer to the alleles in a genotype. For the basics of genetics, we can say that each allele is either dominant or recessive. Dominant is represented by an uppercase letter, and recessive a lowercase. If the genotype is AA, it is homozygous dominant. If it is aa it is homozygous recessive. If it is Aa, it is heterozygous. Simply, homozygous means that both of the alleles are the same and heterozygous means it has one of each allele.
What is the differences between homozygous dominant and homozygous recessive and heterozygous?
A homozygous dominant genotype means that both alleles for a trait are dominant. A heterozygous genotype means that one allele is dominant and the other is recessive. A heterozygous genotype will express the dominant phenotype, not the recessive phenotype.
