Question
DRAGON A
Trait
Temperature-Sensitive Allele
You are a bearded dragon breeder and would like to know what possible dragon colors and markings
you could have if you breed the following two dragons:
Dragon A (ZW): HhttggBb
Genetic Stripe (G/g)
Hypomelanism
Translucent
Genetic Stripe
Leatherback
Sex Reversal
DRAGON A
1) Using Punnett Squares, determine which genotypes are possible at each gene locus if you cross
Parent A and Parent B (2 pt).
Hypomelanism (H/h):
Inheritance Pattern
Autosomal Recessive
Autosomal Recessive
Autosomal Dominant
Codominant
DRAGON B
DRAGON B
Dragon B (ZZ): hhTTGGBb
DRAGON
16-4
DRAGON A
Translucent (T/t):
DRAGON B
Spikes/Scales (B/b):
DRAGON B
2) Are there any phenotypes/traits that are NOT possible for offspring of these two bearded dragons to
have? Hint: Analyze each locus from the Punnett Squares you created above. For each Punnett Square,
are there any phenotypes missing from the offspring possibilities? Note: You will lose points for listing
phenotypes that are possible. 2 pts.
3) You discover that the offspring of Dragon A and Dragon B were incubated in warmer temperatures
than normal during development. How would you expect the number of males and females to differ in
that generation? Perform an internet search and provide one scientific reference supporting your
conclusion. 2 pts.
