In Drosophila, singed bristles [sn] and cut wings [ct] are both caused by recessive X-linked alleles. The wild type alleles [sn+ and ct+] are responsible fro straight bristles and intact wings, respectively. A female homozygous for sn and ct+ is crossed to a sn+ ct male. The F1 flies are interbred. The F2 males are distributed as follows:

sn ct 13
sn ct+ 36
sn+ ct 39
sn+ ct+ 12

What is the map distance bwteen sn and ct?

cuz he's blad

explanation:

not sure if this is what you'r looking for eubacteria and archaebacteria

b) the inside picture would look at a very high temperature in a very low ph

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
