Q. What are the haploid and diploid numbers for a fruit fly?
The significant genetic characteristics of fruit flies include: * a diploid number (2n) of 8 chromosomes, and 4 haploid (n) chromosomes; linkage is detected whenever 5 or more genes are studied because with a haploid number of 4 chromosomes, 2 of any 5 genes studied must be on the same chromosome.

Q. Are male fruit flies haploid or diploid?
Normally, flies have either one or two X chromosomes and two sets of autosomes. If there is but one X chromosome in a diploid cell (1X:2A), the fly is male. If there are two X chromosomes in a diploid cell (2X:2A), the fly is female (Bridges 1921, 1925). Thus, XO Drosophila are sterile males.
Q. Why do fruit flies fly around your face?
If you’re finding yourself often swatting those pesky flies away from your face, it’s likely because you’re unknowingly attracting gnats with your scent, which is how they find their targets. Moisture in the form of sweat or mucus around your eyes or nose might also draw gnats to your face, he said.
Q. Where do fruit flies come from all of a sudden?
Where Do Fruit Flies Come From in the House? Infestations have to start somewhere. Fruit flies move into kitchens, bathrooms, and basements if they sense a food source. Overripe fruit on the counter or any fermenting matter in drains, mops, and trash bins appeals to them.
Q. Why do fruit flies have blood?
The fruit fly must have eaten some fruit with a red pigment. The fruit juice was stored in the gut of the fruit fly. When you swatted it, the red fruit juice masked the translucent hemolymph. Fruit flies and some other insects have red hemoglobin, proteins which use iron to to hold or carry oxygen.
Q. Do Fruit Flies feel pain?
Over 15 years ago, researchers found that insects, and fruit flies in particular, feel something akin to acute pain called “nociception.” When they encounter extreme heat, cold or physically harmful stimuli, they react, much in the same way humans react to pain.
Q. Do fruit flies have hearts?
Regular fruit flies have 104 cells making up their hearts, while the fruit flies with the enlarged hearts also had 104 cells in their hearts. If genetically-caused enlargement of the heart works the same way, hearts don’t enlarge by adding cells, they enlarge by beefing up the cells they already have.
