What is the genotype of a carrier: homozygous dominant, heterozygous or homozygous recessive?The genotypeA genotype is the genetic component of a trait. More specifically, this it which alleles contribute to the expression of a phenotypic trait. A phenotype is the actual physic...
Define the following terms: Dominant, Recessive, Homozygous, Heterozygous, Genotype, Phenotype. What is phenotype? What is a phenotype? Define co-dominant and multiple alleles and explain how they are related to A, B, O blood type inheritance?
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...
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...
A child receives one allele for eye color from the mother and one from the father. When a child receives two alleles for brown eyes, the gene ishomozygous dominantfor that trait. If a child receives two different alleles for eye color, the gene for eye color isheterozygous. ...
Homozygous alleles are identical in an organism’s genotype, promoting genetic stability, while heterozygous alleles vary, increasing diversity.
define what a gamete is and tell why it must be haploid identify Mendel’s role in the history of genetics define key terms of genetics: gene, trait, allele, homozygous, heterozygous, dominant, codominant, recessive, genotype, phenotype, carrier, mutation, deletion, duplication define the Law ...
Figure 5.1: Homozygous and heterozygous inheritance Interestingly, many traits that are supposedly one-gene, ormonogenic, traits (like eye color or the curvature of your thumb) are not. Instead, they arepolygenic, controlled by multiple genes. ...
Dominant traits require the presence of only one allele in order for the given trait to be expressed. Recessive traits can only be expressed if the genotype is homozygous. For example, a V-shaped hairline is a dominant trait, while a straight hairline is recessive. In order to have a strai...
What is the difference between a phenotype and a genotype? What is the difference between phenotype and genotype? What features of the pedigree indicate recessive inheritance? What is the phenotype of a cross between homozygous dominant and homozygous recessive parents?
