Final answer:
The probability that two heterozygous lizards will produce an offspring that is homozygous for no stripes is 1/4.
Step-by-step explanation:
The probability that two lizards that are heterozygous for stripes on their tails (Ss) will produce an offspring that is homozygous for no stripes (ss) can be calculated using the Punnett square. The Punnett square is a grid used to visualize the possible combinations of alleles that can be inherited from each parent.
When crossing two heterozygous lizards (Ss x Ss), there are four possible genotypes for the offspring: SS, Ss, Ss, and ss. Out of these four genotypes, only one genotype (ss) represents the offspring that is homozygous for no stripes.
Therefore, the probability of producing an offspring that is homozygous for no stripes is 1 out of 4, which can be represented as 1/4.
