Question

What is the genotype for the individual II-3?

a
Ee
b
attached earlobes
c
unattached earlobes
d
EE
e
ee

Answer 1

To determine the genotype for individual II-3, it is important to know the trait being inherited. Unattached earlobes are typically dominant (represented by a capital letter, E), while attached earlobes are recessive (represented by a lowercase letter, e).

Given the options:

- (a) Ee (heterozygous, one dominant for unattached earlobes and one recessive for attached earlobes)
- (b) attached earlobes (phenotype)
- (c) unattached earlobes (phenotype)
- (d) EE (homozygous dominant for unattached earlobes)
- (e) ee (homozygous recessive for attached earlobes)

Without additional context regarding the phenotype of individual II-3 or their parents, it is not possible to definitively conclude the genotype.

If individual II-3 has unattached earlobes, the genotype could be either EE or Ee. If II-3 has attached earlobes, the genotype must be ee.

Please provide information about the phenotype of II-3 or their family structure to make an accurate determination.
