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).
"Homo" means 'one' or 'the same'. Homozygous alleles are either both dominant or both recessive. In heterozygous alleles, one allele is dominant and the other is recessive
Homozygous 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
BbxBb = 25% homozygous BB; 50 % heterozygous Bb, and 25% homozygous recessive bb.
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
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.
they can not cross breed.
There is no difference.
"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).
Homozygous is the same(purbred) and heterozygous is different(hybrid)
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.
They are the same
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.
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.
one is curved one is straight
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.
heterozygous recessive
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.
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.
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.
