It is a heterozygous genotype for a particular gene if there are two different versions of it. For instance, a heterozygous for eye colour corresponds to say that you have one allele for black and one for brown.

a Homozygous: 由2个遗传型相同的配子结合形成的合子或由这种合子发育而成的个体,自交后代不发生性状分离的个体。例如AA,AABB Homozygous: The zygote or the individual forms which by 2 genetype same gamete union which becomes by this kind of zygote growth, the inbred line descendants does not have ...
state in a Dutch patient with Joubert syn- drome (JBTS).2 However, p.E1086G, which has been annotated as rs148000791 in dbSNP, is present at high frequency in the ExAC database (457 of 119,154 alleles), and 12 individuals were even homozygous for this variant (as of January 2015)....
In the ZZ/ZW GSD system, the ZZ genotype is male (homozygous), and the ZW genotype is female (heterozygous). Because eggs carry either Z or W chromosomes in ZW systems, it is the eggs, not sperm, that determine sex genotype. However, ZW sex determination in birds is more complex than...
other possesses homozygous recessive alleles. The offspring, or F1 generation, produced from the genetic cross of such individuals are allheterozygousfor the specific traits being studied. This means that all of the F1 individuals possess a hybridgenotypeand express the dominantphenotypesfor each trait...

This suggests that females homozygous for the 'horned allele' have a horned phenotype in only 22% of the cases while 78% will be knobbed or have scurs. The GWAS using EAC on 4001 animals and 510,174 SNP genotypes from the Illumina Ovine high-density (600k) chip gave a stronger ...
A recessive trait is one that is only expressed when an organism has two recessive alleles for that trait. They are less common than dominant traits in most populations because dominant traits will appear in those with both homozygous dominant and heterozygous alleles. What are examples of recessiv...
