What doesheterozygousmean? Heterozygous(and its less common formheterozygotic) means “relating to a cell that has two different alleles for a particular gene at corresponding positions on homologous chromosomes.” Remember, a chromosome carries genes in linear order; a gene is a segment of code t...
An allele isa variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. ... Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two...
Before we begin, let's assume that the sire and dam of the filly were NOT homozygous for the color gene themselves...they had one dominant and one recessive allele for the color trait (dun and/or black). Non-homozygous horses (heterozygous for a trait) will throw their visible trait 50...
A classic example of dominance isthe inheritance of seed shape (pea shape) in peas. Peas may be round (associated with allele R) or wrinkled (associated with allele r). In this case, three combinations of alleles (genotypes) are possible: RR and rr are homozygous and Rr is heterozygous....
Each genetic trait can be located at a particular site or locus on a chromosome, and in a pair of homologous chromosomes, there will be two copies of the alleles which code for a particular trait. In homozygous animals, these alleles are identical. Heterozygous animals have two different allel...
What is heterozygous in autosomal dominant traits? What is autosomal chromosome abnormality? What does autosomal dominant genetic disorder mean? What does autosomal dominant trait mean? What kind of DNA testing is there besides autosomal? Are all Mendelian traits autosomal?
If two heterozygous individuals for a recessive disease (carriers) have a child, what is the chance that their child will develop the disease? What are alleles and how do they relate to genetics? In a monohybrid cross from heterozygous parents, of the offspring ...

What do the missing values and the heterogeneity of ALT mean? Does this mean that it is different from the heterozygous mutation of "REF/ALT", which is different from " 0/0" or " 0/1"?? Thanks Collaborator AndrewCarroll commented Apr 28, 2020 Hi @tetsuro90 (+ @mlin), The ./0,...
Genotypes can be either homozygous or heterozygous. When the two inherited alleles for a given gene are identical, this specific gene is calledhomozygous. Alternatively, when the two genes are different, the gene is said to be heterozygous. ...
