5.4 INHERITANCE
  • You describe, explain, recognize and apply the following terms; homozygous, heterozygous, gene, alleles, dominant, recessive, carrier, P-generation, F1-generation, F2-generation.   
  • You can use your knowledge about inheritance and a Punnet-square to predict the probabilities of offspring having a given genotype or phenotype.
  • You can explain that you have two alleles for each gene.
  • You can use and recognize the notation for homozygous dominant (AA) /recessive (aa) and heterozygous genotypes (Aa).  
VWO: 
  • You can recognize, describe and apply in a context what incomplete dominance is.

WORK ON THE LEARNING GOALS
At the end of the lesson, we will check if you have reached the learning goals

Slide 8 - Diapositive

Oliver says: 'all humans have the same genes, but not the same alleles'. Charley says: 'all humans have the same alleles, but not the same genes'.
Who is right?
A
Oliver
B
Charley
C
They both are
D
They are both wrong

Slide 9 - Quiz

short wings in a fruit fly

Slide 10 - Question de remorquage

Some fruit flies have curly wings instead of normal wings (see the pictures below). Answer the questions using the letter R for normal wings and r for curly wings:

normal wings                 curly wings
a. Which is the dominant allele? Give the letter and the characteristic.
b. Which is the recessive allele? Give the letter and the characteristic.
c. What is the genotype of a fruit fly that is homozygous for curly wings? 
d. Which two genotypes will result in the ‘normal wings’ phenotype?
e. Can a fruit fly with curly wings have a heterozygous genotype? Explain your thinking.





Slide 11 - Diapositive

CALCULATE THE CHANCE. 
Check out the steps on page 136.  

Let's practice! A guinea pig is homozygous for blue fur. This guinea pig mates with a guinea pig with yellow fur. Use a punnet square to determine the probability of one of their offspring having blue fur.
