Fainting goats


Tuesday March 12th
Which most likely determines fur color
A.  A Gene     B.  a codon     C.  a base pair     D. a nucleic acid

Which statement best describes a relationship between genetic structures?
A.  Both genes and DNA are made of alleles
B.  Both alleles and DNA are made of genes
C.  Both DNA and alleles are made of chromosomes
D.  Both genes and chromosomes are made of DNA


 What is supposed to be “funny” about this?                                   (What is the function of a Punnett square)  A punnett square is used to predict possible genetic outcomes of  genetic cross
 *Assume that having swag is a Dominant  trait.                                      You obviously have a ton of Swag   )Homozygous Dominant)                                           and you have kids with someone that is Heterozygous for swag.                                            What is the genotypic ratio of your swag  children?  
1:1 Heterozygous: Homozygous Dominant                                           What is the phenotypic ratio of  your swag kids?      
All your children will have swag. 
 I then talked a little about genetic disorders and how they are inherited in the same manor as what we have already talked about


 Then i let you guys watch the video about the fainting goats!

Which lead us into a discussion about more complex forms of heredity.   Obviously these goats have a gene that causes the  myotonia.  It is not always expressed though.  When they are running around normally it is not a problem, but when they are frightened, this turns the myotonia gene On.  More to come on this type of complex genetics.  Here were some of the notes we continued through today
