Reproduction

• What is Asexual reproduction?

  Reproduction that only involves one parent
• What is Sexual reproduction?

  Male and Female sex cells that fuse together to form a zygote
• Why does Asexual reproduction form identical copies?

  Due to the cell not fusing with another cell, it carries the same genetic information as the parent cell
• What are another word of cells made by Asexual reproduction?

  Clones
• What is Meisos?

  Cell division that produces four, non-identical haploid sex cells
• What is Mitosis?

  Cell division that produces two identical diploid cells
• Where does Meiosis happen?

  In the Male and Female reproduction organs
• What is a Gene?

  Segment of DNA that is a code for a specific type of protein
• How can genes inherit?

  • Genes can inherit traits from a single gene (e.g - Fur colour)
  • Genes can inherit traits from several genes that interact with each other (e.g - Height of a organisms)
• What is an allele?

  A variation of a gene
• What happens when you get a gene from both parents?

  The gene could inherit the same or different alleles
• What is the name for two identical alleles?

  Homozygous
• What is the name for two different alleles?

  Heterozygous
• What happens when an organisms has two different alleles?

  The dominant allele will be expressed
• What happens in a Heterozygous pairing?

  1 Dominant allele, 1 Recessive allele
• What happens in a Homozygous pairing?

  2 Dominant alleles or 2 Recessive alleles
• What are the types of a Homozygous pairing?

  • Homozygous Dominant ( Pairing of 2 dominant alleles)
  • Homozygous Recessive ( Pairing of 2 Recessive alleles)
• What is a Genotype?

  A collection of alleles
• What is an Phenotype?

  Characteristics from the Genotype
• What is an example of a Genotype?

  Homozygous Dominant & Homozygous Recessive = Different genotype
• What is an example of a Phenotype?

  Heterozygous & Homozygous Dominant have the same Phenotype
