Mendelian Genetics
This scientist is known as the "Father of Genetics" because of his pea plant experiments.
Who is Gregor Mendel?
This process reduces chromosome number from diploid to haploid.
What is meiosis?
AB blood type is an example of this inheritance pattern because both alleles are fully expressed.
What is codominance?
The probability of flipping heads on a coin once.
What is 50% (1/2)?
A chart used to trace inheritance patterns in families.
What is a pedigree?
Mendel's law stating that allele pairs seperate during gamete formation.
What is the Law of Segregation?
This event during prophase I increases genetic variation by exchanging DNA between homologous chromosomes.
What is crossing over?
Snapdragon flower color inheritance, where red and white parents produce pink offspring demonstrates this pattern.
What is incomplete dominance?
This statistical test is used to compare observed and expected genetic outcomes.
What is the chi-square test?
This disorder is caused by an extra copy of chromosome 21.
What is down syndrome?
An organism with two different alleles for a trait called this.
What is heterozygous?
The random alignment of homologous chromosome pairs during metaphase I is called this.
What is independent assortment?
Traits controlled by many genes are described as this.
What are polygenetic traits?
If the probability of inheriting allele A is 1/2 and the probability of inheriting allele B is 1/2, this rule is used to determine the probability an offspring inherits both alleles.
What is the multiplication rule?
Cystic fibrosis is inherited as this type of trait.
What is autosomal recessive?
What is 25%
A human body cell contains this number of chromosomes.
What is 46?
This inheritance pattern is commonly associated with disorders such as hemophilia and red-green color blindness.
What is X-linked recessive inheritance?
A chi-square test resulting in a p-value greater than 0.05 means scientists should do this with the null hypothesis.
What is fail to reject the null hypothesis because the differences are likely due to chance?
If two carriers for cystic fibrosis have a child, this is the probability the child will have the disorder.
What is 25%?
Mendel's law stating that genes for different traits separate independently during gamete formation is called this.
What is the Law of Independent Assortment?
Failure of chromosomes to seperate properly during meiosis is known as this.
What is nondisconjunction?
Environmental factors influencing phenotype without changing genotype demonstrate this concept.
What is phenotypic plasticity?
In a dihybrid cross of AaBb x AaBb, this fraction of offspring is expected to be homozygous recessive for both traits.
What is 1/16?
A trait that appears in every generation and only requires one allele is most likely this type of inheritance.
What is autosomal dominant?
