Genetics Review - the whole Enchilada | Baamboozle - Baamboozle

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 humans, chromosome pairs 1-22 are called

Autosomes

Karyotypes are used to diagnose

Chromosomal Abnormalities (Genetic Disorders)

A failure for chromosomes to separate appropriately during meiosis leading to too many or too few chromosomes in a sex cell

Non-disjunction

When neither alleles is dominant so a blending of the two occurs as a third phenotype

Incomplete Dominance

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

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

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

In addition to genetics, this will also determine phenotype for many traits

the environment

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

In blood groups, A and B are not dominant to each other. This is an example of

Codominance

A gene that is located only on the X-chromosome is said to be inherited in this way

X-linked

Examples of this type of inheritance are human skin tone, hair color, and eye color.

Polygenic

When two or more pairs of genes are expressed as one phenotype?

Polygenic trait

This is a tool for predicting the possible genetic outcomes for the children with known parental traits

Punnet Square

Assuming that a trait follows simple Mendelian Genetics - each child should receive this many alleles per trait?

2 (one from mom, one from dad)

One parent gives a dominant allele, the other parent gives a recessive allele - the child is _________ .

Heterozygous

True/False - Blue eye color is an example of a genotype

FALSE - that's a phenotype

The physical expression of the genes into a trait that can be seen or measured

Phenotype

The genetic makeup of an organism is called

Genotype

These are made up of sections of DNA and are passed down from parents to children

Genes

In a heterozygous organism (ex: Dd), which trait would not be seen?

Recessive

Different forms or versions of a gene are called

Alleles

The genotype GG is known as _________________ .

Homozygous dominant

What is any characteristic that can be passed from parent to offspring?

Trait
