Name: ________________________ Core: ___ Date: ___________ DRAGON GENETICS 1. In dragons, the allele for fire-breathing is dominant. Dragons can be fire breathers or non-fire breathers. Show the genotypes and phenotypes of all possible dragons. Use F and f for your alleles. 2. If a heterozygous fire-breathing dragon is crossed with one that does not breathe fire, what is the percent chance that the offspring will be firebreathers? Show your work with a Punnett Square. 5. If you crossed two wingless dragons, what percent chance is there that their offspring will have wings? Show your work. 6. Two winged dragons produce offspring that does not have wings. What are the genotypes of the parents. Show your work. 3. If two heterozygous dragons are crossed, what is the percent chance that the offspring will NOT be fire-breathers? Show your work. 7. If a purebred winged dragon is crossed with a purebred wingless dragon, what is the percent chance that their offspring will be winged? What is their genotype? Show your work. 4. In dragons, wings are a dominant trait. Dragons can have wings or not have wings. Show the genotypes and phenotypes of all possible dragons. Use W and w for your alleles. 8. A hybrid dragon with wings is crossed with one that does not have wings. What is the percent chance that their offspring will be wingless? Show your work. A female dragon (Table 1) is married to a male dragon (Table 2). They are interested in finding out the probability of which traits their offspring will have. Fill in the missing genetic information in the table below for both monsters. Genotypes and Phenotypes for Dragon Traits: Red eyes are dominant (E) to green eyes (e). Thick tails are dominant (T) to thin tails (t). Spikes on the tail are dominant (S) to no spikes on the tail (s). Sharp teeth are dominant (H) to rounded teeth (h). Wings are dominant (W) to being wingless (w). Five claws are dominant (C) to three claws (c). Blue skin is dominant (B) to red skin (b).
