Meiosis I
This is the first step in cell division that reduces the chromosome number in gametes.
What is meiosis?
The primary purpose of Meiosis II in cell division.
What is to separate sister chromatids?
The Mendelian law stating that each allele in a pair separates into different gametes.
What is the Law of Segregation?
The Mendelian law that explains the random assortment of genes from different traits.
What is the Law of Independent Assortment?
The definition of a dihybrid cross.
What is a genetic cross that examines two traits?
The term for the structure formed when homologous chromosomes pair up closely during prophase I.
What is a tetrad?
The type of cell that begins Meiosis II.
What is a haploid cell?
The type of plants Mendel studied to discover this law.
What are pea plants?
The experiment Mendel conducted to discover this law.
What is a dihybrid cross?
The typical phenotypic ratio found in the F2 generation of a dihybrid cross.
What is 9:3:3:1?
This stage of meiosis I is when crossing over typically occurs.
What is prophase I?
The outcome of Meiosis II.
What are four genetically unique haploid cells?
This process describes how alleles separate during meiosis.
What is segregation?
An example of two traits that can assort independently in pea plants.
What are seed color and seed shape?
An example of a dihybrid cross in pea plants.
What is crossing plants with yellow round seeds and green wrinkled seeds?
One major difference between mitosis and meiosis I.
What is the reduction in chromosome number?
One major difference between Meiosis I and Meiosis II.
What is that homologous chromosomes separate in Meiosis I, while sister chromatids separate in Meiosis II?
This is how the law of segregation contributes to gamete formation.
What is each gamete receives only one allele for each gene?
The reason the law of independent assortment is crucial for this genetic concept.
What is genetic diversity?
The number of possible gamete combinations in a dihybrid cross.
What is four (e.g., AB, Ab, aB, ab)?
The number of chromosomes in each cell after meiosis I is complete.
What is half the original number?
The specific role of anaphase II in cell division.
What is the separation of sister chromatids?
An example of segregation in plants.
What is a monohybrid cross of purple and white flowers?
An example of independent assortment in a dihybrid cross.
What is when yellow and round seeds assort independently from green and wrinkled seeds?
The main purpose of using a dihybrid cross in genetics.
What is to examine the inheritance of two traits and demonstrate independent assortment?
