In a unique species of plants, flowers may be yellow, blue, red, or mauve. All colors may be true-breeding. If plants with blue
Zolol [24]

Answer:

F1) 100% bbRr, red flowered plants.

Explanation:

<u>Available data:</u>

  • flowers may be yellow, blue, red, or mauve
  • colors may be true-breeding
  • the cross of blue-flowered plants with red-flowered plants, produce plants that have yellow flowers
  • F2 generation: 9/16 yellow, 3/16 blue, 3/16 red, and 1/16 mauve.

Knowing that the phenotypic ratio is 9:3:3:1, we can assume that there are two genes involved in the flower color expression. We can name these genes B and R with a dominant and a recessive allele each (B, b and R, r respectively).

According to the first cross, we might establish the following genotypes:

1st Cross: blue-flowered plant     x     red-flowered plant

Parentals)         BBrr                     x                bbRR

Gametes)     Br, Br, Br, Br                         bR, bR, bR, bR

F1) 100% BbRr, yellow plants

Parentals)   BbRr     x     BbRr

Gametes) BR, Br, bR, br

                BR, Br, bR, br

Punnett square)     BR       Br        bR          br

                  BR     BBRR    BBRr   BbRR     BbRr

                  Br      BBRr     BBrr     BbRr      Bbrr

                  bR     BbRR    BbRr    bbRR      bbRr                    

                  br      BbRr     Bbrr      bbRr      bbrr

F2)  9/16 yellow ---> 1/16 BBRR + 2/16 BBRr + 4/16 BbRr + 2/16 BbRR  

       3/16 blue ------> 1/16 BBrr + 2/16 Bbrr

       3/16 red---------> 1/16 bbRR + 2/16 bbRr

       1/16 mauve ----> 1/16 bbrr    

So,

  • Yellow-flowered plants: BBRR, BBRr, BbRR, BbRr
  • Red-flowered plants: bbRR, bbRr
  • Blue-flowered plants: BBrr, Bbrr
  • Mauve-flowered plants: bbrr

According to these genotypes, the second cross would be like following,

2nd Cross: true-breeding red-flowered plants with true-breeding mauve flowered plants.                

Parentals)          bbRR       x        bbrr

Phenotype)       Red                   Mauve

Gametes)   bR, bR, bR, bR      br, br, br, br

Punnett square)    bR       bR        bR        bR                    

                    br    bbRr     bbRr    bbRr     bbRr

                    br    bbRr     bbRr    bbRr     bbRr

                    br    bbRr     bbRr    bbRr     bbRr

                    br    bbRr     bbRr    bbRr     bbRr

F1) 100% bbRr, red flowered plants.

Are Fungi beneficial or harmful? Explain
Nata [24]

Answer:

Honestly it depends...

Explanation:

I would say overall fungi are beneficial because they feed on dead organic matter. They recycle most of the carbon and release nutrients to be used by other organisms. They are also used for medicinal purposes. Not to mention yeast is a fungus and bread is yummy.

But certain fungi are deadly if ingested or linked to plant and human diseases. Also mold is a fungus and nobody likes mold.
