Height, hair color, eye color, and weight are all examples of polygenic traits. Some diseases like high blood pressure, diabetes, and asthma are regulated by multiple genes. What is polygenic inheritance? Give a
This mutation results from expanding the number of trinucleotides repeats within particulargenes. Clinical examples include: Fragile X Syndrome: mental retardation is more common in males than females. Fragile S is inherited as an X-linked disorder which presents more in males. ...
(a) Differentiate between genotype and phenotype. (b) Give examples of each. Define these terms: genotype, phenotype. Define allele, gene, dominant, and recessive as they relate to patterns of inheritance. Define the term allele as used in genetics. ...

Examples of the dangers of a lack of genetic diversity are found in agriculture. Modern crops have been selected for their enhanced efficiency in food production but tend to be more susceptible to disease epidemics and have a reduced capacity to adapt to changes in environmental conditions. ...
One concern in human genetic engineering is that this will lead to a loss of genetic diversity62,63. Examples of the dangers of a lack of genetic diversity are found in agriculture. Modern crops have been selected for their enhanced efficiency in food production but tend to be more susceptible...
Give some examples. How many recessive alleles for a trait must an organism inherit to show a trait? What is the relationship between traits and genetics? How can you tell if a trait is determined by more than one gene? What is the inheritance type when traits blend to show an ...
(sometimes single-sex), and/or few offspring, preventing meaningful interpretation of inheritance patterns; however, interaction of multiple sex alleles may produce skewed sex ratios or non-viable genotypes. In cichlids and other fish species, co-segregation of both Y and W alleles in families ...
