Answer:
Explanation:
The parents phenotypes are
TTff x TtFf
The f1 genotype will be
TTFf, TTff, TtFf, Ttff
The phenotypic ratio of tall and orange colored is 4/8= ½
The phenotypic ratio for tall and white is 4/8= ½
The genotypic ratio for each is ¼
 
        
                    
             
        
        
        
Answer:
One popular definition is that organisms are open systems that maintain homeostasis, are composed of cells, have a life cycle, undergo metabolism, can grow, adapt to their environment, respond to stimuli, reproduce and evolve.

Answer:
c. 28
Explanation:
Plant A has a dipoid chromosome number of 12, so its gametes will have an haploid number of 6 chromosomes.
Plant B has a dipoid chromosome number of 16, so its gametes will have an haploid number of 8 chromosomes.
<h2><u>Plant A</u>                      <u>Plant B</u></h2><h2>2n = 12                       2n = 16</h2><h2>  n = 6                          n = 8</h2><h2 />
The new species C arises as an allopolyploid from A and B. An allopolyploid usually originates from the breeding of two different species.
In this case, <u>a gamete from plant A combines with a gamete from plant B to form a hybrid with 14 chromosomes</u> (6 from A and 8 from B). These chromosomes are unpaired, so the hybrid is sterile.
In order to become a fertile diploid individual of species C, the most common mechanism is polyploidization, where the genome duplicates. <u>That way, the resulting plant C has a diploid number of 14 x 2 = 28 chromosomes</u>, of which 12 are A and 16 are B.
