5 True/False Questions
Haploid → A cell having two chromosome sets, or an individual having two chromosome sets in each of its cells i.e. possessing homologous chromosomes. One set from mother (maternal set) one from father (paternal set)
Homozygous gene pair → A gene pair having two different alleles for a characteristic ed. Aa or Bb.
Gene → The fundamental physical and functional unit of heredity that carries information from one generation the the next
Nucleotide → A large membrane bound structure with a eukaryote cell. Contains the genetic material or DNA.
Cytokinesis → Type of cell division that is used for growth and repair or damaged tissues.
