Consequently, a test cross can help determine whether a dominant phenotype is homozygous or heterozygous for a specific allele. Diploid organisms, like humans, have two alleles at each genetic ...
Blood tests from children hospitalized with malaria found that nearly all were homozygous for the wild type of sickle cell allele. The few sickle cell carriers among them had the mildest cases of ...
In its simplest form, a test cross is an experimental cross of an individual organism of dominant phenotype but unknown genotype and an organism with a homozygous recessive genotype (and phenotype).
Statins lower plasma cholesterol by upregulating LDL receptor gene expression and are consequently relatively ineffective in homozygous familial hypercholesterolemia (HoFH). The standard treatment ...
The genotype is a set of paired symbols used to represent the alleles present. The genotype can be homozygous (the same, BB or bb) or heterozygous (different, Bb).
Individuals A and B both have brown eyes, even though A is heterozygous and B is homozygous (dominant). Only people with a homozygous recessive genotype can have blue eyes as shown by individual C.
