With reference to Figure 3.3 in the previous post, describe how the family picture shown demonstrates the principles of genetics.
Assume that parents are homozygous for all traits examined.
- Body shape
Round body shape is dominant over giraffe body shape! The offspring demonstrates the same body shape as its' "I am NOT a pig" parent.
Sadly, this is the case of most of us - the endomorphs of the world unite! Yeah! Then again, giraffe body shape is not much better - note the pear shaped figure!
- Fur colour
Mottled giraffe markings are dominant over red fur. This is shown by the offspring inheriting mottle-y markings.
- Body size
Inherited in an incompletely dominant fashion. Alternatively, this may be an example of multifactorial inheritance.
- de novo mutations
Items such as the appearance of horns and shaggy scruffy fur.
