Vocabulary
An alternative form of a gene
What is an allele?
What the alleles on the top and side of the Punnett square represent
What are parental gametes?
This type of allele always is expressed fully when it is present.
What is a dominant allele?
Mendel's law that states that some alleles are dominant and some alleles are recessive
What is the Law of Dominance?
These are the 3 alleles in the human population for blood types
What are IA, IB, and i?
What is homozygous?
What the genotypes inside the boxes of the Punnett Square represent
What are the possible outcomes/zygotes of the cross?
In a certain species of rabbit, there are 4 different alleles in the population: C, cch, ch, and c. Two parent rabbits that are Ccch and Cc mate. How many alleles will their baby get?
What is 2?
(regardless of the number of alleles in a population, individuals still receive just 2 - 1 from mom, and 1 from dad)
Mendel's law that we have come to learn as meiosis.
What is the law of segregation?
These are the 4 phenotypes for human blood typing
What are Type A, Type B, Type AB, and Type O?
Mendel's term for heterozygous
WHat is hybrid?
The genotype ratio when Mendel crossed a homozygous dominant plant with a homozygous recessive plant
What is 0:4:0?
One species of rabbit has 3 phenotypes: black, white, and gray. What is the most likely inheritance pattern for coat color in this rabbit?
What is incomplete dominance?
Mendel's law that states traits that are located on separate chromosomes are inherited separate from each other.
What is the law of independent assortment?
What is codominance?
Another term for a physical characteristic that is controlled by a gene(s)
What is a trait?
The phenotype ratio when Mendel crossed a heterozygous purple flower with a heterozygous purple flower?
What is 3:1?
In humans, predisposition to certain diseases like diabetes and cardiovascular disease results from the accumulation of alleles from many different genes, showing this inheritance pattern.
What are polygenic traits?
Mendel's law that states parent alleles are separated into separate gametes, so a parent can only give one of their alleles for a particular trait to each offspring but not both.
WHat is Law of Segregation?
The number of genotype possibilities for human blood type in a population
What is 6?
The likelihood an event will happen
What is probability?
The expected phenotype ratio for a true dihybrid cross.
What is 9:3:3:1?
For sickle cell anemia, someone who is heterozygous for red blood cell shape makes both normal shaped cells and sickle shaped cells, an example of this type of inheritance pattern.
What is co-dominance?
Mendel tested this law using a 16 box Punnett Square.
What is the law of independent assortment?
The reason why a person with blood type AB cannot have a type O parent.
What is they received an A allele from one parent and a B allele from the other and a type O parent can only donate the O allele?
