Question

Scenario 3: A one-eyed flying people-eater usually has purple skin. One-eyed fying people caters who are recessive for skin color are bineA heterozygous purple one eyed people eater has offspring with an bino female one-eyed people cater. Value: 1 Which of the following are the genotypes of the parents? (select one for each parent.) Imark all correct answers] a. Father - PP b. Father - Pp c. Father - pp d. Mother - PP e. Mother - Pp Mother - pp g. Not enough information is given to determine the father's genotype h. Not enough information is given to determine the mother's genotype Check Answer

Answer 1

First Question:

The answer will be father- Pp & mother- pp (Option b & f).

Explanation: According to the question, usually one-eyed flying people-eater has purple skin & recessive genotypes are albino. Thus, homozygous dominant & heterozygous will have purple skin & they will have PP & Pp genotype respectively. So, genotype of albino will be pp. As father is heterozygous, his genotype will be Pp & as mother is albino, her genotype will be pp.

Note: According to the options given, P is dominant to p.

Second Question:

The answer will be Pp & pp (Option b & c).

Explanation: The cross between Pp & pp is shown in below Punnett square.

Gametes	p	p
P	Pp	Pp
p	pp	pp

From the above Punnett square, we find that possible genotypes of offspring will be Pp & pp.

Third Question:

The answer will be 50% (Option c).

Explanation: The cross between Pp & pp is shown in below Punnett square.

Gametes	p	p
P	Pp (Purple skin)	Pp (Purple skin)
p	pp (Albino)	pp (Albino)

From the above Punnett square, we find that chance that their offspring will be albino is 2/4 or 50%.
