RT 114. <p>The <b>Mount Hope Bridge</b> is a two-lane <a href=/pages/w/111852695494261>suspension bridge</a> spanning the <a href=/pages/w/110959148954433>Mount Hope Bay</a> in eastern <a href=/pages/w/108295552526163>Rhode Island</a> at one of the narrowest gaps in <a href=/pages/w/109279189090026>Narragansett Bay</a>.
For example, diploid human cells contain 23 pairs of chromosomes (46 total), half of maternal origin and half of paternal origin. Meiosis produces haploid gametes (ova or sperm) that contain one set of 23 chromosomes. When two gametes (an egg and a sperm) fuse, the resulting zygote is once again diploid, with the mother and father each contributing 23 chromosomes.
In meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells each with half the number of chromosomes as the original parent cell.he homologous chromosomes are then segregated into two new daughter cells, each containing half the number of chromosomes as the parent cell. At the end of meiosis I, sister chromatids remain attached and may differ from one another if crossing-over occurred.
