Science 4

• Tiny units

  Genes
• Cell division that produces sex cell

  Meiosis
• the chromosomes of each gamete are reduced into half

  haploid number
• Certain cells in your body contain the same number of chromosomes 

  Germ cells
• The process of creating an ovum or an egg cell

  Oogenisis
• the sperms are also created in a process

  Spermatogenesis
• the smallest unit of a living thing

  cell
• It has how many organelles?

  7
• the control center

  Nucleus
• The nucleus has a

  nuclear membrane
• you can see threads called

  Chromatin
• the chromatin forms a rod-like structure

  Chromosome
• the nucleus divides and produces two daughter cells

  Somatic cells
• the chromatin in the nucleus begins to shorten and form rod-like shape structures

  Prophase
• the spindle is fully developed and the chromosomes begin to attach themselves to it

  Metaphase
• separate and moves towards the poles

  Anaphase
• the polar fibers continue to lengthen until the nuclei begin to form

  Telophase
• The two nuclei are identical to each other. The cell cannot be completed with a nucleus alone.

  cytokenisis
• difference of two-or more individual from each other.

  variation
• Traits shown

  Doninant
• Recessive

  traits hidden
• Homozygous

  The same traits
• Heterozygous

  Different traits
• Genotype

  Genes Form
• Phenotype

  Physical form
• Resting stage

  Interphase
• Father of modern genetics

  Mendels laws
• Only one form of trait appears

  Law of dominance
• Genes separates each other

  Law of segregation
• two (or more) different genes get sorted

  Law of Independent assortment
• The traits of the parents mixed

  Co-dominance
