(A) In metaphase I, tetrad sets of homologous chromosomes stay together as they line up along the center of the cell.
Explanation:
In meiosis, homologous chromosomes pair with each other (i.e., they form tetrads) and crossing-over occur. In mitosis, not of these things occur. In metaphase I of meiosis, tetrads follow on the metaphase plate. In mitosis, there is only one state and it creates two daughter cells
The major difference betwenn metaphase I (meiosis) and metaphase (mitosis) is: <span>(A) In metaphase I, tetrad sets of homologous chromosomes stay together as they line up along the center of the cell.
They concluded that horses evolved with the emergence of grasslands and an increase of predators. The digits of their early Eocene ancestor evolved into hooves.
