a cell type that has half the alleles of a somatic cell - haploid a condensed form of DNA and proteins that can be seen during mitosis and meiosis; each one contains several genetic loci - chromosomes a condensed form of DNA and proteins that can be seen during mitosis and meiosis. These contain the genes. - Chromosomes A diploid cell becomes two haploid cells during which phase? - meiosis I a disease inherited on a dominant allele that results in progressive deterioration of the nervous s...

What are clones? - ️️Genetically identical copies. The term can apply to cells or whole organisms. How are clones produced? - ️️By asexual reproduction in which the nucleus is divided by mitosis. Mitosis creates two identical copies of DNA, which are then separated into two genetically identical nuclei before the cell divides to form two genetically identical cells. These cells may not be physiclly or chemically identical as, after division, they may differentiateto form two d...
