These structures are called Vestigial structures, they resemble structures from the organism's ancestors, but don't have a real purpose for them now. 

Pray this helps you :)

Some examples of non-polar molecules include fats, oils, and waxed. How do these substances interact with water?
77julia77 [94]
Since non-polar molecules are equally distributed and positively charged atoms in contrast with polar molecules. Thus, like fats oils and waxes, these materials are composed mainly of lipids or in the group of fats and are conspicuously insoluble with water. How do these substances interact with water? They are hydrophobic, thus, they don't "mix" with water. Unlike water and other polar molecules that are unequally and negatively distributed and charged making them able to bond with other molecules like oxygen and other polar molecules and substances.

Examine the genotype for an individual who is AaBbCcDc. Predict the outcomes of meiosis and the potential gamete combinations th
Katarina [22]

Answer: 16 different gametes

  1. ABCD
  2. ABCd
  3. ABcD
  4. ABcd
  5. AbCD
  6. AbCd
  7. AbcD
  8. Abcd
  9. aBCD
  10. aBCd
  11. aBcD
  12. aBcd
  13. abCD
  14. abCd
  15. abcD
  16. abcd

Explanation:

Gamete formation involves the random and independent segregation of alleles. During anaphase 1 (meiosis), occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair.  

The number of gametes with different combinations is 2ⁿ, where  

n = number of homologous pairs.  

In the exposed example there are 4 pairs of chromosomes, so

the number of possible combinations of chromosomes = 2ⁿ = 2⁴ = 16

Individual: AaBbCcDdEe

You can make use of the fork line method to easily figure out the possible gametes.

A.......B.........C........D → ABCD

                     ........d → ABCd

          ...........c.........D → ABcD

                       ........d → ABcd

           b.........C........D → AbCD

                     ........d → AbCd

          ...........c.........D → AbcD

                       ........d → Abcd

a.......B.........C........D → aBCD

                     ........d → aBCd

          ...........c.........D → aBcD

                       ........d → aBcd

           b.........C........D → abCD

                     ........d → abCd

          ...........c.........D → abcD

                       ........d → abcd
