|
Gregor Mendel
|
He worked with peas.
|
|
|
An trait that is hidden and does not show in an individual. This trait can be passed onto their children.
|
A recessive trait.
|
It is not dominant.
|
|
|
Both alleles are the same.
|
Homozygous
|
It can be dominant or recessive.
|
|
|
The alleles are different.
|
Heterozygous
|
The prefix of this word means "different"
|
|
|
How many alleles are there for blood type and what are they?
|
There are three alleles: A,B,O
|
Start at the beginning of the alphabet.
|
|
|
A range of hair color in our population indicates this type of inheritance.
|
Polygenic inheritance
|
The prefix of this word means "many"
|
|
|
A chart used to follow a genetic trait from generation to generation.
|
Pedigree
|
A brand of dog food
|
|
|
Hemophilia and colorblindness are examples of this kind of genetic disorder.
|
Sex-linked disorder. The defective gene is located on the X chromosome.
|
Male or female
|
|
|
Why do males have a greater chance of having a sex-linked disorder than females?
|
Because the gene is on the X chromosome and males only have one X chromosome.
|
|
|
|
In pea plants, short is the recessive allele. What is the probability that two heterozygous(Tt)pea plants will have offspring that are also heterozygous?
|
50%

|
|
|
Four o'clock flowers have two alleles for flower color, red and white. Why is it that there are 3 colors of four o'clock flowers?
|
When both the red and white allele are inherited, both of the alleles are expressed, resulting in a third color, pink.Incomplete dominance.
|
No recessiveness here.
|
|
|
The genes an organism has for a given trait.
|
Genotype
|
Can be RR, Rr, rr...
|
|
|
The physical expression of the genes for a trait.
|
Phenotype
|
their looks
|
|
|
Which blood type allele is always recessive?
|
O
|
It's not A
|
|
|
A disease where the red blood cells are misshapen.
|
Sickle cell anemia
|
The grim reaper carries one
