Based on the textbook's description of the inheritance of hair texture, can two parents heterozygous for wavy hair still produce
Alinara [238K]
Heterozygous means that each parent has a dominant gene and a recessive gene. Using C as dominant for wavy hair and c for recessive meaning it will be curly, there is .25 that have CC, .25 that have cc, and .50 that have Cc. 

There is a 25% chance that parents who are heterozygous for wavy hair will have a child with curly hair.

Why is meiosis important for organisms? It allows for genetic variation among organisms. It determines which genes are dominant
Studentka2010 [4]

Meiosis is important for organisms since it allows for genetic variation among organisms.

<h2>Further Explanation</h2><h3>Cell division</h3>
  • Cell division is the process in which cells undergo division to form other new cells.
  • There are two types of cell division;
<h3>Mitosis Division  </h3>
  • Mitosis is a type of division in which a parent cell undergoes division to yield two daughter cells that are similar to the parent cells.
  • The daughter cells have equal number of chromosomes as the parent and are identical to the parent.
  • This type of cell division normally occurs in somatic cells of organisms and facilitates growth and development of organisms.
<h3>Meiosis division</h3>
  • Meiosis division is a type of division that occurs in gamete cells where a parent cell divides into four daughter cells that differ from the parent cells in terms of the number of chromosomes.
  • In meiosis the daughter cells have half the number of chromosomes as the parent cells.
  • Meiosis occurs in the gamete cells and facilitates sexual reproduction in living organisms.
  • Meiosis occurs in two phases, that is, meiosis I and meiosis II
  • During the process of meiosis several processes occurs that cause genetic variation among organisms.
  • These processes include, crossing over, independent assortment of genes, among others.
<h3>Crossing over  </h3>
  • Cross over is the process that occurs during the prophase I phase of the first stage of meiosis known as meiosis I.  
  • During the process of crossing over, genetic material is exchanged between homologous chromosomes which enhances the genetic variation in organisms.

Keywords: Cell division, meiosis, crossing over, genetic variation
