Mystery bull punnet square

1. All red offsprings

2. All roan (RW) offsprings

Explanation:

According to this question, the allele for red color (R) is codominant with the allele for white color (W). Hence, an heterozygous cattle will give a roan color (RW).

- for cross 1 between RR and RR, only R gametes will be produced by both parents, hence, all the offsprings of this cross will possess a RR genotype i.e. all red traits

- Also, in cross 2 between RR and WW parents, RR will produce gametes R while WW will produce gametes W, hence, all the offsprings will have a genotype RW i.e. roan color

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
