Question

Which finger mutation is commonly associated with various developmental conditions and is linked to genetic traits?

a) Thumb mutation
b) Pinky mutation
c) Index finger mutation
d) Middle finger mutation

Answer 1

The pinky finger mutation is commonly linked to developmental conditions. Polydactyly, or having six fingers, is rare yet due to a dominant allele. Hox gene mutations can result in phenotypes with fewer appendages.

Step-by-step explanation:

The finger mutation commonly associated with various developmental conditions and is linked to genetic traits is pinky mutation. However, in relation to the questions provided, the answer to which allele is often linked to polydactyly, or having six fingers, is that it is caused by a dominant allele. Most people have five fingers because the polydactyl allele is very rare in the human population. When it comes to Hox gene mutations, these could lead to a phenotype such as having two fewer appendages than normal. Genetic markers, such as the BRCA genes related to breast and ovarian cancers, are identified and studied to understand hereditary diseases better and to provide options for prevention, such as surgeries in high-risk individuals.
