A genetic cross of inbred snapdragons with red flowers with inbred snapdragons with white flowers resulted in F1-hybrid offspring that all had pink flowers. When the F1 plants were self-pollinated, the resulting F2-generation plants had a phenotypic ratio of 1 red: 2 pink: 1 white. The most likely explanation is what mode of inheritance

The correct answer is - incomplete dominance type of inheritance.

Explanation:

Incomplete dominance is a type of inheritance pattern where the heterozygous condition of the alleles leads to the blend of both dominant and recessive alleles phenotype. In this case, red snapdragon and white snapdragon flowers crossed and produced pink flowers, which is a blend of both traits due to incomplete dominance of the red or dominant allele.

In such a pattern, the heterozygous condition only shows the mix or hybrid phenotype and parental phenotypes reappear in F2 when heterozygotes are crossed.

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.
