Verified step by step guidance
1
Understand the concept of independent assortment: Independent assortment is a principle of genetics that states that alleles of different genes are distributed independently of one another during the formation of gametes. This occurs during metaphase I of meiosis when homologous chromosome pairs align at the metaphase plate.
Understand the concept of segregation: Segregation refers to the separation of alleles during gamete formation. This occurs during anaphase I of meiosis when homologous chromosomes are pulled to opposite poles of the cell.
Evaluate the statement about segregation: The statement 'Segregation refers to the random distribution of sister chromatids during meiosis II' is incorrect because segregation refers to the separation of homologous chromosomes during anaphase I, not sister chromatids.
Evaluate the statement about independent assortment: The statement 'Independent assortment occurs during metaphase I of meiosis' is correct because this is when homologous chromosomes line up independently of each other, leading to genetic variation.
Evaluate the statement about the result of independent assortment: The statement 'Independent assortment results in the production of identical gametes' is incorrect because independent assortment increases genetic diversity, resulting in genetically unique gametes.
