Who is the father of genetics?
Gregor Mendel
An trait that is hidden and does not show in an individual. This trait can be passed onto their children.
A recessive trait.
Both alleles are the same.
The alleles are different.
How many alleles are there for blood type and what are they?
There are three alleles: A,B,O
A range of hair color in our population indicates this type of inheritance.
Polygenic inheritance
A chart used to follow a genetic trait from generation to generation.
Hemophilia and colorblindness are examples of this kind of genetic disorder.
Sex-linked disorder. The defective gene is located on the X chromosome.
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?
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.
The genes an organism has for a given trait.
The physical expression of the genes for a trait.
Which blood type allele is always recessive?
A disease where the red blood cells are misshapen.
Sickle cell anemia
True or False. A recessive genetic disorder can only be inherited if both alleles are recessive
The disease when the blood does not clot properly. Sometimes called the bleeder's disease.
