Question

Trinucleotide repeat alleles that are not associated with the disease phenotype but that can expand during meiosis are known as:

A Permutations
B Pseudo-disease alleles
C Pre-expansions
D Expansion-prone alleles
E Unstable alleles

Answer 1

Expansion-prone alleles are trinucleotide repeat alleles that are not associated with the disease phenotype but can expand during meiosis. An example is the trinucleotide repeat in the Huntington's disease gene.

Step-by-step explanation:

The trinucleotide repeat alleles that are not associated with the disease phenotype but can expand during meiosis are known as Expansion-prone alleles. These alleles have the potential to increase in size when they are passed on to the next generation. An example of an expansion-prone allele is the trinucleotide repeat in the Huntington's disease gene. The number of repeats can increase, leading to the development of the disease in future generations.
