Answer: Haploid cells contain a single set of chromosomes while diploid cells contain two sets of chromosomes. Haploid cells have half the number of chromosomes as in the parent cell while diploid cells contain the same number of chromosomes as the parent cell.
Explanation: Diploid cells contain two sets of chromosomes while haploid cells contain one set of chromosomes. Diploid cells undergo mitosis while haploid cells undergo meiosis. Diploid cells produces two daughter cells in mitosis while haploid cells produce four daughter cells in meiosis. Diploid cells have (2n) number of chromosomes while haploid cells have (n) number of chromosomes. Diploid cells are somatic cells or body cells while haploid cells are sex cells or gametes. Diploid cells are involved in body growth and repair while haploid cells are involved in sexual reproduction.

Answer:
The duplication of a cluster of four Hox genes is equally likely as the duplication of a single Hox gene.
Explanation:
This comes from the definition of the parsimony principle, which is the action of choosing the simplest scientific explanation fitting the given evidence, meaning that all other elements are equal when evaluating the hypothesis. In biology the best hypothesis is the one that requires the fewest evolutionary changes.
Since three independent duplications of an individual Hox gene is in evolutionary terms, more complex than a single duplication or a cluster, then that hypothesis would be the most parsimonious.
