Chromosomal Rearrangements: Duplications Practice Problems

Dr. Xavier D. Chew wants to create a hybrid between a donkey (2n=62) and a horse (2n=64) to create a new species called a "don-horse." He plans to induce chromosome doubling in the hybrid to stabilize the genome. What is the most likely outcome regarding the fertility of the resulting don-horse?

Which of the following genetic mutations will not show any phenotypic change?

Which of the following mechanisms can lead to the formation of duplicate genes within an organism's genome, and what are the possible fates of these duplicate genes?

Dr. Picasso wants to cross a female horse with a male donkey to create a new species. What will be the chromosome number in a hybrid produced by crossing a horse (2n = 64) with a donkey (2n = 62)?

Which of the following terms best describes the unusual structure that forms during pairing of the homologous chromosomes In Prophase-1 of meiosis-1?

Both deletion and duplication causes alteration of the chromosome, which of the following can be expected from said alterations:

Modern vertebrate genomes reflect paleopolyploidy since the early vertebrate lineage's genomes underwent two whole genome duplications. This assertion defines:

If a sequence ABCDEF undergoes a tandem duplication, what could the resulting sequence be?

Identify the correct statement about large segmental duplications in organisms:

Which type of duplication results in the duplicated segment being inserted into a new location within the genome?
