Which of the following options correctly describes the functions of both cilia and flagella? Excretion   Protection   Locomotion       Body’s defense       BENTEN: During meiosis I, pairs of homologous chromosomes align randomly along the metaphase plate before being separated. This process helps generate genetic variation in the offspring of sexual reproduction. Which of the following best explains how the random alignment of homologous chromosomes during meiosis helps generate varied offspring?      Random alignment increases the likelihood of crossing over between non-sister chromatids.   Random alignment results in the formation of gametes that contain different numbers of chromosomes.   Random alignment increases the number of possible chromosome combinations in the gametes.   Random alignment results in the formation of some diploid and some haploid gametes.
