What is heredity?
Heredity is the transmission of traits from one generation to the next.
What process results in the reduction of chromosome number in cells?
Meiosis, which involves two cell divisions leading to haploid cells.
What are gametes?
Gametes are reproductive cells that transmit genes from one generation to the next.
What is the result of asexual reproduction?
Asexual reproduction produces offspring that are genetically identical to the parent.
What is synapsis during meiosis?
Synapsis is the pairing of homologous chromosomes during prophase I of meiosis.
What happens during crossing over?
Crossing over involves exchanges between non-sister chromatids within a tetrad, resulting in new combinations of genes.
What is the significance of crossing over?
Crossing over is an important source of genetic diversity.
What occurs during Anaphase I of meiosis?
Homologous chromosomes separate, while sister chromatids remain connected.
What is the outcome of meiosis II?
Meiosis II results in the separation of sister chromatids into daughter cells.
What are the stages of meiosis I?
The stages include Prophase I, Metaphase I, Anaphase I, and Telophase I.
What is disjunction in meiosis?
Disjunction is the process by which homologous chromosomes are separated during Anaphase I.
What is interkinesis?
Interkinesis is the time between the first and second meiotic divisions, typically a short interphase-like stage.
