Atall pea plant (tt) and a tall pea plant (tt) have the same
(a) alleles.
(b) phenotype.
(c) genotype.
(d) filial type.

Phenotype.

Explanation:

Genotype may be defined as the genetic constituent of the organism. Phenotype is the physical appearance of the organism that can be modified by the organism's genotype.

The tall pea plant (TT) and (Tt) constitute the same phenotype as both the genotypes are responsible for the appearance of the tall height of the plants. The phenotype of the plant is controlled by its genotype.

Thus, the correct answer is option (B).

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
