Answer:
Outcome of irregular mitosis:
Mitosis may be defined as the process of cell division in which a single diploid parent cell divides to form two diploid daughter cells. The irregular mitosis may result in aneuploidy condition of chromosome in which the the extra (trisomy) or missing (nullisomy) of one or more chromosome may occur. This condition also leads the genetic disease and cancer condition. Non disjunction may occur in which the sister chromatid are unable to separate.
Outcome of irregular meiosis I and meiosis II.
Meiosis is the cell division in which a single diploid parent cell divides into four haploid daughter cells. Nondisjunction at meiosis I prevent the segregation at least one homologous chromosomes. This causes the two cells with extra copy of chromosome and two cells with deleted chromosome. Nondisjunction at meiosis II. Two cells have normal chromosomes and two cells with the abnormal (missing and extra) chromosomes.
Answer:
Habitat alteration-every human activity can alter the habitat of the organisms around us. Farming, grazing, agriculture, clearing of forests, etc. This is the greatest cause of biodiversity loss today.
Explanation:
:)
The types of mutations include: Missense mutation. This type of mutation is a change in one DNA base pair that results in the substitution of one amino acid for another in the protein made by a gene. Nonsense mutation.
