Since white coloring in guinea pigs in recessive we will say its "rr" and if cross a heterozygous black guinea pig that would be "Rr" so if we cross that in a punnet square The offspring will be two heterozygous black guinea pigs and two white recessive guinea pigs.

From this cross, it is expected to observe 50% of white coloring guinea pigs and 50% black guinea pigs.

  • In diploid organisms, offspring receive to gene form or alleles (one of each parent) for a given gene locus.

  • In cases of complete dominance, the dominant allele masks the expression of the recessive allele in heterozygous individuals.

  • In this case, the cross between a homo-zygous recessive and a heterozygous will produce individuals in 1:1 proportion.

In conclusion, from this cross, it is expected to observe 50% of white coloring guinea pigs and 50% black guinea pigs.
