If two roan cattle were crossed, then 50% percent of the offspring are expected to have a roan coat color.
- A heterozygous individual is an organism that carries out two different alleles for the same gene locus.
- In this case, the 'roan' coat color is observed in heterozygous individuals (genotype R1R2).
- In consequence, the cross between two heterozygous individuals will produce a progeny in a 1:2:1 proportion.
In conclusion, if two roan cattle were crossed, then 50% percent of the offspring are expected to have a roan coat color.
