Students have asked these similar questions
..explain why meiosis occurs only in specialized cells (gametes), and
that the overall goal of meiosis is to make haploid cells for sexual
reproduction
• ..outline the sequence of key chromosomal movements and
rearrangements during the two meiotic divisions, identifying key
similarities and differences between meiosis and mitosis
• ..describe the ploidy of a cell before and after meiosis I and meiosis II,
and how ploidy changes after separation of sister chromatids and
homologous chromosomes
WHAT IF? Why did the researchers split each female frog’s eggs into twobatches for fertilization by different males? Why didn’t they mate each femalewith a single male frog?
Help please!!!
