A hybrid allotetraploid species (2n1 + 2n2 = 60) was backcrossed to one of the suspected parents (2n1 = 30). What is the ploidy
leonid [27]

Answer:

45 chromosomes (2n1 + n2)

Explanation:

The allotetraploid 2n1+2n2=60 has 60 chromosomes total, two sets of them of type 1 and two sets of chromosomes from the other type (2).

If the suspected type 1 parent is diploid with 30 chromosomes, then the allotetraploid has 30 type 1 chromosomes and 30 type 2 chromosomes.

<u>During meiosis, the germ cells reduce the total chromosome number by half.</u>

  • The gametes produced by the allotetraploid will have 15 type 1 chromosomes and 15 type 2 chromosomes.
  • The gametes produced by the suspected parent will have 15 type 1 chromosomes.

When these gametes combine during the backcross, the F1 zygote will have a diploid number of 30 type 1 chromosomes (15 coming from the allotetraploid and 15 coming from the suspected parent) and 15 type 2 chromosomes (which will be haploid because they all came from the allotetraploid).

Into what kingdom would each of the following be classified: Unicellular prokaryotes that live in dust. ______________________ U
Anuta_ua [19.1K]

Answer:

Unicellular prokaryotes that live in dust: Eubacteria

Unicellular eukaryotes that line in pond water: Protista  

Multicellular eukaryotes that live all over the planet and consume food: Anamalia  

Unicellular prokaryotes that live in volcanic ash: Archaebacteria  

Multicellular eukaryotes that have cell walls and are heterotrophic: Fungi  

Multicellular eukaryotes that have cell walls and are autotrophic: Plantae

Explanation:  

Prokaryotic organisms can be classified into two groups: Eubacteria and Archaebacteria. Eubacteria (i.e.,“true” bacteria) are unicellular prokaryotic microorganisms that live in normal environmental conditions. On the other hand, Archaea (Archaebacteria) are prokaryotic older organisms that thrive in extreme conditions (in this case, volcanic ash). Moreover, eukaryotic organisms can be classified into four kingdoms: Protista, Plantae, Fungi and Animalia. Protista are unicellular eukaryotes that live in different aquatic environments (i.e., oceans, ponds, streams, etc). Animals are multicellular, mobile, heterotrophic (i.e., organisms that cannot produce its own food) organisms whose cells lack walls. Fungi are heterotrophic organisms that acquire their food by absorbing dissolved organic compounds, whose cells have cell walls (but they lack chloroplasts). Finally, plants are multicellular autotrophic (i.e., organisms that produce their own food) organisms whose cells contain walls and chloroplasts (to produce food by photosynthesis).
