KS3/4 GENETICS – JAGUAR MELANISM CASE STUDY COLLECTION

Spot the odd one out…

Get to the bottom of our black panthers’ dark coat colouring by applying Mendelian genetic theory. Your students will test hypotheses on Goshi’s genotype by creating Punnett squares, and predict the likely coat colour of her potential offspring with Homozygous Recessive mate Napo. Then explore how natural selection can influence the genotype distribution of Jaguars in the wild.

Science

KS3

Working scientifically:

  • make predictions using scientific knowledge and understanding

Genetics and evolution

Inheritance, chromosomes, DNA and genes:

  • Heredity as the process by which genetic information is transmitted from one generation to the next
  • The variation between species and between individuals of the same species means some organisms compete more successfully, which can drive natural selection
  • Changes in the environment may leave individuals within a species, and some entire species, less well adapted to compete successfully and reproduce, which in turn may lead to extinction

KS4

Working scientifically:

  • The development of scientific thinking using a variety of concepts and models to develop scientific explanations and understanding-
  • Experimental skills and strategies using scientific theories and explanations to develop hypotheses
  • Analysis and evaluation, interpreting observations and other data, including identifying patterns and trends, making inferences and drawing conclusions

Evolution, inheritance and variation:

  • Single gene inheritance and single gene crosses with dominant and recessive phenotypes
  • Genetic variation in populations of a species
  • The process of natural selection leading to evolution
