Indicate the coat color and the proportion of offspring with that color for each of the following crosses of rabbits. Assume all
PolarNik [594]

Answer:

C) all chinchilla

Explanation:

As we know that dominance of alleles for the coat color in rabbits goes like this:

                                          C+ > Cch > Ch > C.

  • The allele for full colour or agouti is  designated as C+.
  • Allele for mutant coat color  silvery- gray coat-chinchilla is Cch.
  • Allele for “Himalayan” coat is called ‘Ch
  • Albino rabbits have whole white coat and allele for this is c

If we cross homozygous chinchilla with homozygous chinchilla the cross will look like this:

P1:                                            chinchilla x chinchilla

P1:                                             Cch Cch    X   Cch Cch

F1:                                          Cch Cch       :       Cch Cch

Since all offspring have Cch Cchgenotype that is foe chinchilla phenotype  it means that all the offspring will have chinchilla phenotype that makes option C correct.

Two species of garter snakes live in the same geographic area. One lives mainly in water and the other mainly on land; therefore
11111nata11111 [884]

Answer:

The correct answer is ecological isolation.

Explanation:

The condition when two species in spite of living in the same region, exhibits certain characteristics, which inhibits them from mating with each other is termed as reproductive isolation. The obstructions or the causes that prevent them from interbreeding is known as isolating mechanisms.  

The given case is an example of ecological isolation and is one of the forms of reproductive isolation. Habitat or ecological isolation refers to the phenomenon in which two species cannot mate with each other as they thrive in two distinct locations. Like as mentioned, two species of garter snakes though coming from the same geographical area cannot interbreed, as one of them is living in the land and the other one in the water.

Is it a, b, c, d ???
OLga [1]

Answer:

I believe that it is D.
