Typically when graphed, the frequency of these types of traits show a bell shaped curve
Polygenic Trait
A single trait that has 3 or more alternative forms. These are called
Multiple alleles
This pattern of inheritance is demonstrated when a gene from one locus can prevent the full expression of another gene at a different locus.
Epistasis
The gene combinations such as heterozygous, or Aa are called
Genotype
3/4 orange tabby cats are male. This is because the gene for this trait are found on the _______________ .
X Chromosome
General genetics terms that refers to what you see, or the physical appearance of an organism
Phenotype
Males are more likely to inherit a sex linked trait due to the fact that they have only one __________ chromosome
X
A red flowered plant was crossed with a white flowered on. Their species shows co-dominance for this trait. What color will the offspring's flowers be?
Red and white (bicolored)
Certain types of color-blindness are more common in males than in females because they are inherited in this pattern
Sex-linked
A red flowered plant was crossed with a white flowered on. Their species shows incomplete dominance for this trait. What color will the offspring's flowers be?
Pink
True or False: Men can NEVER be "carriers" for recessive sex-linked traits because they only have one X chromosome.
True
Human hair, eye, and skin color are all examples of
Polygenic traits
Genetics is just one contributing factor to phenotype, another important factor is
the environment
This is when a trait is controlled by more than one PAIRS of genes
Polygenic trait
If a gene is found only on the X chromosome and not the Y chromosome, it is said to be what?
Sex linked Trait
This is the chromosome that carries the male genetic traits
Y
When one allele is not dominant over the other, resulting in both traits expressed in a heterozygous individual
Co-dominant
In terms of chromosomes, females receive this combination
XX
A, B, O blood type is a example of this
Multiple Alleles
T/F: Some traits can be due to a combination of inheritance patterns
True
Someone who has AB+ or - blood type is an example of this
Co-dominance
