Select the best answer for the question. 3. In an offspring set, there are two organisms with lobed ears (LI) and two organisms with unlobed ears (II). What is the likely genotype and
phenotype of the unknown parents?

Note about the question:

Options are missing in the problem statement, and I failed in finding them. However, here is my answer and explanation.

• Genotype: Ll and ll

• Phenotype: One parent has lobed-ears (Ll) and the other one has  

      unlobed-ears (ll)

Explanation:

Due to technical problems, you will find the complete answer and explanation in the attached files

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.
