What is the phenotype of a heterozygote? What is the phenotype of a heterozygous individual for eye color, if blue is recessive and brown is dominant? What is the genotype of a carrier: homozygous dominant, heterozygous or homozygous recessive? What is the genetic condition in which the hete...
What type of allele is always expressed regardless of whether the individual is homozygous or heterozygous for it? A. Both the dominant and recessive alleles B. Recessive allele C. Allosteric allele D. Lethal allele E. Dominant allele What is the genotype of a ...
Hybrid or heterozygous organisms carry two different alleles for a trait. Homozygous organisms carry the same alleles for a trait. An organism's genotype describes the gene combination the organism inherited. An organism'sphenotypecan be seen in the physical expression of thegenotype. The child with...
The genotype is the combination of genes that cause phenotype, which is how an organism looks or functions. There are three different types of genotypes, which are homozygous dominant, homozygous recessive and heterozygous. All cells, except for reproductive — or sex — cells, contain two copies...
Loss of heterozygosity (LOH) is a common genetic event in many cancer types, so-called because of the early observations of a change in polymorphic markers from a heterozygous state in the germline to an apparently homozygous state in the tumour DNA [2]. LOH is a general term that encompass...
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...
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. ...
435 non-normozoospermic Caucasian men, the genotype frequencies of a polymorphism of the interleukin-1 beta gene (IL-1 beta Taq C-->T) were statistically significantly different between groups (homozygous wild-type C/C [57%], heterozygous C/T [42%], and homozygous mutant T/T [1%] vs...
When a person has a heterozygous genotype, with one normal and one mutated copy ofHEXAthey do not have the Tay-Sachs phenotype, but are actually incompletely dominant at the protein level. These people have lessHEXAthan unaffected individuals, but the amount produced is enough to evade the phen...
What is codominance? What do you call the organism having two identical alleles of a gene? A. allele B. autosome C. codominance D. dominant E. gene F. genotype G. heterozygous H. homozygous I. incomplete dominance J. phenotype K. recessive L. sex chromosomes ...
