Question

Drag each label to the correct location on the image.

Smooth hair is dominant in horses, and curly hair is recessive. Black hair is dominant, and chestnut hair is recessive. If S denotes smooth and s denotes curly, B denotes black and b denotes chestnut, classify the alleles according to their types.
SS BB bb Ss Bb ss

Answer 1

SS + BB = dominant
Ss + Bb = heterozygous
bb + ss = recessive
both lowercase represents a recessive gene, for example if the horse has ss it’s hair would be curly
if it has Ss while it’s hair would be straight there still could’ve been a possibility for curly hair which is why it’s heterozygous
and SS is dominantly straight hair with no chance of curly making it a dominant.
