False
Because the predators would have more food if the prey increased
Incomplete dominance is an exception to Mendelian principles of genetics. The pink flowers of a petunia plant result from incomplete dominance and this has been experimentally determined.
The crossing between petunia plants shows an exception to Mendel’s principles. As a result of crossing the first generation homozygous petunia plants, some alleles of the first cross generation of the petunia flowers were in between the two dominant alleles which meant they were neither dominant nor recessive to the characteristics.
The F1 generation produced by a crossing the red-flowered (RR) plants and the white-flowered (WW) petunia plants consisted of pink-coloured flowers (RW) as the first progeny. Neither of the allele was dominant here. The cases where one allele does not completely dominate another are known as incomplete dominance. The heterozygous phenotype is supposed to occur between the two homozygous phenotypes in incomplete dominance. Phenotype refers to the colour here and genotype is a representation of alleles.
The representation of the genotypes is as follows:
White coloured dominant parent petunia plant: WW
Red coloured dominant parent petunia plant: RR
The colours white and red are the phenotypes and WW or RR is the genotype of parental alleles.
When the red and white flowered petunia plants were true breaded which means the red and white flowered petunia plants had red and white colour as their dominant characteristic and they were homozygous.
The result that was seen of this true breeding was heterozygous pink flowered petunia plants in the F1 generation. The pink colour phenotype of the flowers was an intermediate between the two dominant red and white coloured petunia flowers. This meant that the allele for the red flowers were incompletely dominant over the white flowers giving rise to pink flowers.
The genotype of the pink coloured petunia flowers as well as the corresponding phenotype can be represented by the Punnet squares.
The fundamental and functioning unit of genetics is called genes. They are units of DNA that produce proteins that control the characteristics of organisms.
<h3>What is the role of genes?</h3>
Genes are the basic and fundamental of inheritance and are made up of deoxyribonucleic acid. The variation of the gene of the same trait forms the alleles.
They code for the proteins that produce protein or RNA structures. Genes are located on the chromosome structure and code for proteins that play an important function and role in cell activity.
Therefore, option D. genes are a section of DNA that codes for proteins is correct.

<span>A) change their views about minorities.
Jackie Robinson became the first "black" to play professional baseball in the United States. He proved that black people are also as competitive as those with white people.

Founder effect is the example of migration of a random few individuals from one population to a new area to establish a new population.Thus, option C is correct.
What is migration?
Migration is defined as movement of individuals from one place to another in search of employment and livelihood.Some people lives permanently after migration and some returns back to the native place.
Internal migration is the type of migration in which people migrate within state and country.
External migration is the migration to different state and country.
The phenomenon of moving into new place is known as immigration.
Seasonal migration is the migration in which animals or humans migrate in a particular season due to climatic condition.
Therefore,migration of a random few individuals from one population to a new area to establish a new population is an example of founder effect.
