Диплоидный набор клеток картофеля - 48 хромосом. Сколько бивалентов образуется в клетках картофеля во время профазы1 мейоза? а)24 б)48 в)12 г)96 д)36

Answer 1

Набор хромосом в профазе1 мейоза не изменяется, значит б

Answer 2

Number of Bivalents in Potato Cells during Prophase I of Meiosis

The diploid set of chromosomes in potato cells is 48. During prophase I of meiosis, homologous chromosomes pair up to form bivalents. Each bivalent consists of two homologous chromosomes, which means that the number of bivalents formed in potato cells during prophase I of meiosis would be half of the diploid set.

Therefore, the correct answer is (a) 24 bivalents.
