Думаю, что 22 хромосомы...Ведь в метафазу 1 гомологичные хромосомы располагаются по экватору клетки.

Автор ответа: Loskut

Так как в яйцеклетке 22 хромосомы ,то в соматической клетке - 44 хромосомы.В профазу 1 мейоза можно обнаружить 22 бивалента,так как биваленты - это пары коньюгированных хромосом.
