Answer:
Option B, Co-dominance
Explanation:
This is an example of codominance inheritance pattern.
When two alleles representing two different characteristic traits are expressed equally in the offsprings resulting from a cross, then this genetic inheritance pattern is called as codominance .
For example -
A red flower with genotype "RR" is crossed with a white flower "rr" resulting into pink color offsrping with genotype "Rr"
Here, both the red and white traits of flower color are expressed equally thereby giving pink color to the offspring flower.
The same thing is happening in case of true breeding black and white mice.
Hence, option B is correct

Answer:
They have a gizzard to grind the food.
Explanation:
Birds cannot chew since they have no teeth. However, the beak allows them to split very large seeds or swallow them directly.
For their digestion they have a stomach where digestion enzymes are released. Also they have a gizzard that is an organ that grinds the food mechanically. This gizzard usually has small stones inside that were previously ingested and that helps to digest the food.
