Why may they still be considered two distinct species? In the wild, members of one species prey upon members of the other species O Zoos are not natural environments.

How does prophase I differ from prophase II? Durine prophase there is one diploid cell during prophase If there are two haploid cells. Tetrads do not form during prophasel; tetrads form during prophase Il During prophase I chromosomes line up single file on the midline of the cell during prophase II the chromosomes line up in double file on midline of the cell During prophase I the nuclear envelope breaks up; during prophase II the nuclear envelope remains intact During prophase I chromatin condenses chromatin does not condense during prophase II. How does prophase I differ from prophase II? Durine prophase there is one diploid cell during prophase If there are two
