Question

Sometimes pieces of chromosomes are lost or rearranged during the recombination step of meiosis. Chromosome is said to have a ______, these chromosomes can be missing many genes.

a) Duplication
b) Deletion
c) Translocation
d) Mutation

Answer 1

During meiosis, if a chromosome undergoes loss or rearrangement of genes, it is referred to as a deletion. Deletions can result in a large section of a chromosome being lost, affecting multiple genes and potentially leading to genetic imbalances and lethality in diploid organisms.

Step-by-step explanation:

A chromosome that has missing genes due to loss or rearrangement during the recombination step of meiosis is said to have a deletion. Deletions result in a large section of a chromosome being lost and can involve several to hundreds of genes. This can lead to genetic imbalance and can be lethal to a diploid organism.
