1 When black and brown dogs are crossed, all the dogs of F1 generation are foundp black. Give reasons of not forming brown dogs. Also give a chart.
m. ​

The black dogs are h o m ozygous with a dominant trait, but the brown dogs are h o m ozygous with a recessive trair. So if the dogs breed their offspring will all be black because black is dominant to brown, so therefore black is expressed.

Diagram is in the pic above

Blue box is black dog

Red box is brown dog

A is the allele for black

b is the allele for brown

A is dominant so b, so A is expressed
