WebScience Biology 1. If a particular species of plant is made up of cells that each have 30 separate chromosomes, 15 of which appear to be paired in terms of size and shape, what is the “ploidy” of this plant? What is the term for these similar chromosomes? What is the ploidy of a different plant species in which the cells also have 30 ... WebJun 16, 2024 · In meiosis I, chromosome homologs—the paternal and maternal chromosome homologs—are segregated (so-called ‘reductional’ segregation causing reduction in ploidy).
