B, C, D, and G 2. B, C, F, and G Different finch species have beaks of different shapes and sizes. What do these beak differences tell us? A. Different finch beak shapes are evidence that finch species adapted to different environments over many generations. B. Different finch beak shapes are evidence that several finch species with different beak types came to the Galápagos Islands from the mainland. C. Different finch beak shapes are evidence that all Galápagos finches share a common ancestor. D. Different finch beak shapes are evidence that individual birds changed their beaks so that they could feed efficiently. A Genetic evidence supports which of the following explanations for the presence of 13 different finch species on the Galápagos islands?

Get answer to your question and much more 12.This animation illustrates ______ as it occurs during _______ Do homologous chromosomes lined up independently?The spindle fibres align the homologous chromosomes on the metaphase plate. Pairs of homologous chromosomes (tetrads) are lined up independently of each other (maternal and paternal chromosomes are also lined up on the metaphase plate at random).
At what stage in meiosis are homologous chromosomes paired and lined up in the center of the cell quizlet?During metaphase I the paired homologous chromsomes (tetrads) align at the center of the cell (the metaphase plate).
What are homologous pairs of chromosomes quizlet?Homologous chromosomes are chromosome pairs, one from each parent, that are similar in length, gene position and centromere location. Homologous chromosomes are two sister chromatids stuck together with cohesions forming a tetrad.
Does crossing over prevent homologous chromosomes from separating during meiosis?True Crossing over prevents homologous chromosomes from separating during meiosis I. False For crossing over to occur, homologous chromosomes must align precisely early in prophase I so that nonsister chromatids can exchange corresponding segments of DNA.
