In a fruit fly experiment, grey body, normal winged (homozygous dominant) fruit flies were mated with black body, short winged (
bogdanovich [222]

Answer:

In a fruit fly experiment, grey body, normal winged (homozygous dominant) fruit flies were mated with black body, short winged (homozygous recessive) fruit flies. The F1 dihybrid females were then used in a test cross. If the genes are always linked and no crossing over occurs, what would be the predicted ratio in the F2 generation?

GG x bb = Gb, Gb, Gb and Gb  F1 generation

grey body heterozygous offspring 4:0

Gb x Gb= GG, Gb, Gb, and bb F2 generation

3:1 three grey body fly and one black body fly

State one adaptation of nephron in the kidney of a desert mammal​
lidiya [134]

Answer: The desert animals do not get appreciable amount of water quantity to survive on daily basis instead their body mechanism tries to conserve water by concentrating urine.

The desert mammal like kangaroo rat produces hyper concentrated urine so as to conserve water. It is facilitated by extremely long loop of Henle in their nephron. The long loop of Henle increases the time and space for absorption of water and nutrients from the urine filtrate. Hence, urine so produced is more concentrate and conserve water. Moreover, the kangaroo rat consume their urine to survive in extreme hot desert condition in scarcity of water.

Describe the manner in which you would determine how long ago two species of bacteria diverged from one another.
Andrei [34K]

Answer:

One of the probable ways to determine how long ago any two species of bacteria diverged from each other is by drawing a phylogenetic tree.

Explanation:

  • Phylogenetic tree are trees that show the ancestry of two species of interest and the relationship between them.
  • The idea behind the construction of phylogenetic tree is darwins's "descent with modification theory".
  • A phylogenetic tree is constructed using the similarities or differences in either physical characteristics, behavorial, or genetic buildup.
  • Derived traits shared between the different species are the actual data used to construct a phylogenetic tree.
