The allele for black fur is dominant over the allele for white fur.
5. Cross this heterozygous black rabbit with the white one. What is the probability of white furred offspring?

10. H=healthy h= tongilitis #6
Daniel has tongilitis, his wife Semone does not.
Daniel’s mother and father, Tyreek and Cheyenne, are both healthy.
Daniel’s sister, Danielle, is healthy. Their brother John has tongilitis.
Semone’s mother, Daisha, is healthy. Her father Malik has tongilitis.
Daniel and Semone have three children. Noelani and Jaisha are both healthy, but Kaseem has tongilitis.
H=healthy
h= tongilitis

6. The allele for detached ear lobes is dominant over attached ear lobes. Find a partner and create a Punnett square to determine what your offspring would look like. If you have detached ear lobes assume you are heterozygous for that trait. What is the probability of your offspring having detached ear lobes?
D= detached ear lobes
d= attached ear lobes

12. Science Starters R= can roll tongue r= can’t roll tongue
8. Scientists believe that the ability to roll ones tongue is controlled by a single gene. The ability to roll your tongue is dominant. Not being able to roll your tongue is recessive. Find a partner and make a Punnett square to chart your possible offspring. If you can roll your tongue assume you are heterozygous for that trait. What is the probability of your offspring being able to roll their tongues.
R= can roll tongue
r= can’t roll tongue
