Haplodiploidy 9. Males bees are known to develop parthenogenically from unfertilized eggs and are therefore haploid. Females (both workers and queens) originate from fertilized (diploid) eggs. Sex chromosomes are not involed in this mechanism of sex determination which is characteristic of the insect order Hymenoptera. The quantity and quality of food available to the diploid larvae determine whether that female will become a sterile worker or a fertile queen. Thus environment here determines sterility or fertility but does not alter...

In Drosophila, the autosomal recessive brown eye color mutation
(b) displays interactions with both the X-linked recessive
vermilion mutation (v) and the autosomal recessive scarlet (s)
mutation. Flies homozygous for brown and simultaneously hemizygous
or homozygous for vermilion have white eyes. Flies simultaneously
homozygous for both the brown and scarlet mutations also have white
eyes. Flies that are wildtype at all 3 loci have wildtype eye
color. Flies that are homozygous or hemizygous for the recessive
mutant at only one...

Question 8 1 pts Which of the following is NOT true about sexual selection? Sexual selection operates only on males because they are the ones that compete and females are the "choosy" ones Wb Which types of sexual signals evolve in a given lineage may depend on pre-existing sensory biases (eg. whether individuals can see in color, or what sounds they like) Sexual signals are often "expensive" (in energy, or risks to safety), which means that usually only healthy individuals...
