What is a polygenic trait? What does it mean that an allele is "dominant" as opposed to being "recessive?" What is a recessive allele? Explain the difference between a dominant and a recessive condition. Provide an example. What does an allele do? How is it determined if it is recessive...
What is the difference between heredity and heritability? What is meant by a gene locus? Define "heritability" and, with reference to a human trait, explain why it is different from "inheritance". What is meant by the genetic code being redundant? Give two examples. ...
Traits that display a continuous distribution, such as height or skin color, arepolygenic. The inheritance of polygenic traits does not show the phenotypic ratios characteristic of Mendelian inheritance, though each of the genes contributing to the trait is inherited as described by Gregor Mendel. W...
This is pleiotropy, but they did not use the term—see below; (iii) multiple alleles can be found at a given locus, resulting in various manifestations of a trait (for instance white/red/eosin eye color). In addition, they reported various cases where a genetic difference is not visible ...
What is meant by a recessive gene? Which two alleles are farthest apart? Which genotype (Homozygous dominant, Heterozygous, Homozygous recessive) is known just by their Phenotype? Why? What is a Mendelian trait? What is the phenotype of a homozygous dominant organism?
How does polygenic inheritance differ from typical Mendelian inheritance? Be sure to include the special circumstance of epistasis in your answer. Explain the difference between inheritance autosomal or sex-linked diseases. Is there an easy way to know if a disease is inherited or sex-linked?
What is the functional unit of heredity? Describe heredity What is heterozygous? What are the three types of symmetry in biology? What is survival of the fittest in biology? Can a trait be polygenic but not multifactorial? Explain. What is a trait shared by two organisms due to parallel evo...
What type of traits are considered polygenic traits? What are recessive traits? What are polygenic traits in biology? What are single-allele traits? What is an example of a phenotype ratio? What are autosomal traits controlled by? What is a multiple allele trait?
What chromosome is microphthalmia on? What is nondisjunction? What is an autosomal dominant genotype? What do autosomal genes determine? What is not an autosomal recessive trait? What is a haploid dominant species? What are polygenic traits in biology?
A widow's peak is a dominant trait W, while a straight hair-line is recessive. What are the probabilities of having a widow's peak child with mother = ww and father = Ww? What are the three possible genotypes and the two possible phenotypes for a characteristic controlled by t...
