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

Plant species A has a diploid chromosome number of 12. Plant species B has a diploid number of 16. A new species, C, arises as a
Genrish500 [490]

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.
