According to Kansas State University, heterozygous genotypes are those that feature non-identical alleles for a given pair of genes. The term is most often used to describe an organism that has one copy of a recessive gene and one copy of a dominant gene. Because recessive traits are only expressed in an organism’s phenotype if they occur in pairs, such organisms appear normal, even though they possess the recessive gene.Know More
According to the University of Washington, parent organisms that are heterozygous for a recessive gene can produce offspring in one of three combinations. The offspring can have both dominant alleles, both recessive alleles or one of each type of allele. Those offspring with two copies of either gene are homozygous, while the offspring that have both types of allele are called heterozygous.
Southwest Tennessee Community College lists a number of common recessive traits for humans, including short eyelashes, round eye shape and cleft chins. In order for a human to display any of these traits, he or she must have two copies of these genes. People who have only one copy of the gene, or heterozygous individuals, can pass the trait on to their offspring, but they do not display the trait themselves.Learn more about Molecular Biology & DNA
Gregor Mendel chose pea plants for his experiments because they are easy to raise, have many offspring per mating, can fertilize themselves and have varieties in genotype and phenotype that are easily observable. These characteristics make pea plants ideal in the study of genetics and heredity.Full Answer >
The genetic makeup of an organism is known as its genotype. The genotype refers to the set of traits found within the cells of living organisms. These traits, known as the genetic code, are passed from one generation to the another during cell division and reproduction.Full Answer >
Slow responders, a subgroup of hepatitis C patients with genotype 1, benefit from extended treatment between 48 and 72 weeks. After receiving combination therapy for four to 12 weeks, the slow responders can be identified, states PubMed.Full Answer >
Phenotype is an organism's observable properties that are the result of the interaction of the organism's genotype and the environment. Observable properties include things such as eye color, height and hair color.Full Answer >
