Assuming that a trait follows simple Mendelian Genetics - each child should receive this many alleles per trait?
2 (one from mom, one from dad)
In humans, chromosome pairs 1-22 are called
Autosomes
You are looking at a pedigree and you see that a trait does not skip a generation and can be found in all generations. It is most likely inherited as a
Dominant
When two or more pairs of genes are expressed as one phenotype?
Polygenic trait
The genotype GG is known as _________________ .
Homozygous dominant
These are made up of sections of DNA and are passed down from parents to children
Genes
When neither alleles is dominant so a blending of the two occurs as a third phenotype
Incomplete Dominance
In addition to genetics, this will also determine phenotype for many traits
the environment
In blood groups, A and B are not dominant to each other. This is an example of
Codominance
The physical expression of the genes into a trait that can be seen or measured
Phenotype
This is a tool for predicting the possible genetic outcomes for the children with known parental traits
Punnet Square
Examples of this type of inheritance are human skin tone, hair color, and eye color.
Polygenic
A failure for chromosomes to separate appropriately during meiosis leading to too many or too few chromosomes in a sex cell
Non-disjunction
True/False - Blue eye color is an example of a genotype
FALSE - that's a phenotype
When a parent has an allele for a trait and can give it to their children but they are unaffected, we call them _________ .
Carriers
In blood groups, children can receive A, B, AB, or O blood group from their parents depending on what they have to give. This is an example of
Multiple Alleles
You are looking at a pedigree and you see that a trait skips a generation. It can be seen in both males and females. It is most likely inherited as a
Recessive
Karyotypes are used to diagnose
Chromosomal Abnormalities (Genetic Disorders)
One parent gives a dominant allele, the other parent gives a recessive allele - the child is _________ .
Heterozygous
Different forms or versions of a gene are called
Alleles
You are looking at a pedigree and you see that a trait skips a generation and is mostly inherited by males. It is most likely inherited as a
Sex linked trait
A gene that is located only on the X-chromosome is said to be inherited in this way
X-linked
What is any characteristic that can be passed from parent to offspring?
Trait
In a heterozygous organism (ex: Dd), which trait would not be seen?
Recessive
