WebFeb 22, 2024 · Author summary Meiosis is essential for sexual reproduction in most eukaryotes, including plants. In recent years, epigenetic modification such as DNA methylation, histone modifications and histone variants has been shown to play essential roles in meiosis likely by regulating chromatin structure and gene expression. However, … WebMeiocyte has 2n chromosomes. The number of chromosomes in root cells of apple is also 2n and the number of chromosomes in the gametes are n. 2n=34. Number of … this war of mine trap

WebAug 31, 2010 · They were able to identify a whole genome duplication (which they call a genome wide duplication) that occurred in the ancestor of apples 30-65 million years ago. What’s weird is that apple has experienced only one chromosome fusion (starting with an ancestral chromosome set of 9 chromosomes, doubling to 18, and then fusing two … WebApr 8, 2024 · It is clear from the above discussion that yes there is a relationship between the number of chromosomes of meiocytes and gametes of the same species. As on meiosis meiocyte gives rise to gametes. So the number of chromosomes in gametes is half to the number of chromosomes in meiocyte. WebA meiocyte is a type of cell that differentiates into a gamete through the process of meiosis. Through meiosis, the diploid meiocyte divides into four genetically different haploid gametes. The number of chromosomes in apple is 17 when it is haploid, 34 when it is diploid, and 51 when it is triploid. this war of mine ukraine
