  • The white tiger

    fingerprints meaning that no two tigers have the same pattern of stripes. White tigers aren’t necessarily born from other white tigers. White tigers get their color by a double recessive allele. A Bengal tiger with two normal alleles or one normal and one white allele is colored orange. Only a double dose of the mutant allele results in white tigers (www.cranes.org/whitetiger). In fact it is even normal to find normal colored cubs in a litter of white tigers (www.5tigers.org.com). White tigers are a very

  • Biology: Gene and Daughter Cells

    W4Q1 Meiosis is the process by which cells divide and create living creatures. Without meiosis we cannot have the process of mitosis‚ which is the process by which cells of tissue are created for living creatures. When meiosis occurs 4 daughter cells are created‚ while only 2 are created in mitosis. With the creation of 2 daughter cells the new cells will be similar to the parent cell‚ but will have differences‚ as there more parent cells involved. When mitosis occurs the daughter cells will be

  • sex linked genetic disorders

    Sex-linked traits are genetic characteristics determined by genes located on sex chromosomes. Genes are pieces of DNA on chromosomes that carry information that are responsible for inheriting traits. Different forms of the same gene are called alleles. One allele for a certain trait is inherited from a mother and one from a father. These traits are passed down from parent to their offspring by sexual reproduction. Fragile X syndrome (FXS) or Martin-Bell syndrome is a genetic syndrome that causes autism
