1. ___1___ : ____1____ is the ratio of homozygous to heterozygous offspring.

The answer is 1:1. It could also be expressed in percentage which is 50% : 50%. This is derived by dividing the number of a particular genotype against the whole offspring population. In this case, each genotype is 2/4 * 100 in percentage.

2. ___50____ % are the homozygous recessive.

The answer is 50%. Homozygous recessive means that, in the genotype of the offspring, both alleles of the gene are recessive. In this case, it is rr. As indicated above, this is derived by 2/4 * 100 since there 2 out of 4 of the offspring are recessive homozygous.
