Mitosis
What is metaphase?
This is the process in mitosis during which the chromosomes line up in the middle of the cell.
What is Meiosis?
Is a cell division that only occurs in the testes and the ovaries, and forms specialized cells known as gametes
What are the stages of Meiosis 1? Name the first three
Prophase, Metaphase, Anaphase
What is anaphase?
The sister chromatids break apart, and the chromosomes begin moving to opposite ends of the cell. By the end of anaphase, the two halves of the cell have an equivalent collection of chromosomes. In telophase, two daughter nuclei form, and the nuclear envelope begins to reappear.
What is prophase I?
Homologous chromosomes pair up and exchange genetic material through crossing over.
what is the less important stage in mitosis?
All of them play a important role in mitosis
Outline the sequence of events during mitosis
Prophase, metaphase, anaphase, telophase, and cytokinesis
Outline the differences between the processes and outcomes of meiosis I and meiosis II.
Meiosis I separates homologous chromosomes, reducing the chromosome number by half, while meiosis II separates sister chromatids, resulting in four haploid cells
In which stage chromosomes align individually along the metaphase plate.
Metaphase
Evaluate the importance of mitosis in multicellular organisms.
It provides new cells for growth and for replacement of worn-out cells,
describe gametes
A gamete is a reproductive cell of an animal or plant.
Outline the most important stage of mitosis
In this stage the cell ensures that it is ready to divide.
What is the mitotic spindle?
Is a structure, composed of protein filaments, organizes and separates chromosomes during mitosis
Evaluate the genetic Variation
The percentage of polymorphic gene loci or gene loci in heterozygous individuals
Name and describe the key events that occur during prophase I of meiosis, focusing on the processes that lead to genetic variation.
The pairing of homologous chromosomes, the exchange of genetic material between them through crossing over, and the formation of tetrads, which contribute to genetic diversity.
