Early prophase
WebAsexual reproduction involves a single cell dividing to make 2 new, identical daughter cells. Mitosis & binary fission are examples of asexual reproduction. Sexual reproduction involves two cells (egg & sperm) joining to make a new cell (zygote) that is NOT identical to the original cells. Meiosis is an example. 67. WebSep 19, 2011 · Best Answer. Copy.

Web1. Prophase: Prophase starts immediately after G 2 stage of interphase. Chromosomes look like thin thread and uncoiled in the early prophase (Fig. 3.2B), but become shortened, coiled and more distinct during mid-prophase (Fig 3.2C). In the late prophase, chromosomes appear more conspicuous, short and thick and longitudinally double (Fig. … WebOct 27, 2024 · Definition.
