That means the genes determining an organism's heredity are duplicated although their expressions may vary. The normal condition of paired chromosomes is termed DIPLOID. When only one member of a pair is present, the condition is HAPLOID. If the alleles on a chromosome are identical, they are said to be HOMO- ZYGOUS. If they differ, they are said to be HETEROZYGOUS. Flip to the next card. Note: HAPLOID is often designated as N and DIPLOID as 2N. -- part contents for background part 8 ----- text ----- 196
