Which of the following defines polygenic inheritance?
Â
An inheritance pattern in which one allele is not fully dominant over another, so the heterozygous phenotype is an intermediate blend of the two homozygous phenotypes
Â
An inheritance pattern in which the full and separate phenotypic effects of two alleles are apparent in heterozygous individuals
Â
An inheritance pattern in which a single gene affects multiple traits
Â
A pattern of inheritance in which multiple genes affect one trait

Human Phenotypes
Simple dominance inheritance pattern:
Q: How many phenotypes are evident in patterns of simple dominance? What are they?
If a phenotype results from simple dominance, which two genotypes cannot be
distinguished?
Which phenotype is always representative of the genotype?
Now determine your personal inheritance of the following traits. As you read through
the following descriptions, you'll identify your trait, and determine your phenotype.
Your trait will be one of the two
Shape of the face.
Most facial characteristics are affected by many different genes acting together
(multiple factors or polygenic inheritance). For this trait we have simplified the nature
of this trait by assuming it is the result of a single gene. Oval shape is dominant (needs

homozygous (both alleles are the same, either dominant or recessive) or heterozygous
(one dominant allele and one recessive allele). Square shape is recessive (requires that
both alleles are the recessive allele in…
Describe the differences between an incompletely dominant trait and a codominant trait.

One allele causes black fur (X) and one allele gives the cat orange fur (X"). These alleles act in a codominant manner, because when a cat has two different alleles (XB Xb), the cat has a pattern called tortoise shell, where the cat has both orange and black hairs. The Y chromosome does not have this coat color gene There is another gene that affects coat color in cats called the piebalding gene. This gene is on an autosomal chromosome and the alleles affect the amount of white patches that appear in the cat's coat, Some cats (ss) have o white patches and their other colors are blended, not patchy. Some cats (SS or Ss) have white patches and their other colors are…arrow_forward
