analyze this punnett square:

1. in this punnett square, what is the ratio of homozygous to heterozygous offspring? (hint: homozygous means ''the same''; heterozygous means ''different''.)
homozygous: heterozygous

2. in the punnett square, what percentage of the offspring are homozygous recessive?

answers can be in this format:

1. : is the ratio of homozygous to heterozygous offspring.
2. % are the homozygous recessive.

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.
