Answer
This statement is true since male ants develop from unfertilised eggs, and therefore the sperm of a particular male would result in offspring that are genetically identical.
Step 2
B. males can be either homozygous or heterozygous at any gene locus.

Answer
This statement is true, as males can express different alleles for genes, hence they can be either homozygous or heterozygous.
Step 3

Answer
This statement is true. Since unfertilised eggs develop into males without genetic variation, all males from a single female would be genetically identical.
Step 4
D. homologous pairs of chromosomes are found in both male and female ants.
