DNA and Inheritance Model

NGSS HS-LS3-1: Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.

Parent 1 (Mother)

Click the bands on the chromosomes to change her genes.
Chromosome Pair 1
Bb Ee

Parent 2 (Father)

Click the bands on the chromosomes to change his genes.
Chromosome Pair 1
bb ee

Genetic Key:

Top Gene Band (Fur Color):
B = Purple Fur (Dominant)
b = Yellow Fur (Recessive)
Bottom Gene Band (Eye Color):
E = Blue Eyes (Dominant)
e = Red Eyes (Recessive)

Note: All cells in the organism have the same genetic content (these chromosomes). Genes code for instructions that build proteins, which determine these characteristic traits.
