Before meiosis begins, during S phase of the cell cycle, the DNA of each chromosome is replicated so that it consists of two identical sister chromatids, which remain held together through sister chromatid cohesion. This S-phase can be referred to as "premeiotic S-phase" or "meiotic S-phase".
"50" percent of the offspring will be pink is the one among the following choices given in the question that will happen if <span>a red rose is crossed with a pink rose. The correct option among all the options that are given in the question is the third option or option "C". I hope the answer has helped you.</span>
Crossing over<span> occurs </span>between<span> prophase 1 and metaphase 1 and is the process where </span>homologous chromosomes<span> pair up with each other and </span>exchange<span> different segments of their genetic material to form recombinant </span>chromosomes<span>. It can also happen </span>during<span> mitotic division, which may </span>result<span> in loss of heterozygosity. </span>
