Question

The character of the red color in the flower is dominant. What will be the opposite, or comparative character?
A)Dwarf plant
B)Round seed
C)White flower
D)Green seed

Answer 1

Hint: When a trait has two different forms at the level of the gene then the dominant and recessive traits exist. A dominant trait is a trait that appears first or expressed visibly in the organisms and a recessive trait or d trait is masked and not show itself in the organisms at the gene level.

Complete answer:
-In the given question, the trait of the given flower is color and not the height or shape of the seed. Therefore, the given color of the flower i.e red color is the dominant character.
-Therefore, if the dominant trait of the flower is red color then the opposite of comparative character should be a recessive trait.
-So, the red color of the flower is due to the absence of white color. Therefore, the opposite of comparative character is the white flower.

Additional Information: -characteristics such as the color of the eye, skin, or hair color are determined by the genes. In an individual, two alleles are present in each gene i.e. when comes from the mother and one from the father.
-Alleles that determine the expression of a trait are known as dominant alleles and the alleles that are less likely to be expressed are known as recessive alleles.
-The dominant allele usually determines the characteristic when it is paired with a recessive allele.
-when the characteristics are expressed and can be seen known as phenotypes and the genotypes are the trait that is expressed by the genetic code.
-So, Dominant is always expressed when present. When no dominant genes are present only then Recessive is expressed.

So, the correct answer is,” White flower”.

Note: -Monohybrid cross is the cross that comprises a single pair of contrasting characters and it formed the basis of Mendelian genetics and occurs in all the main groups of sexually reproducing organisms.
-With respect to the color of the flower, a monohybrid cross between two homozygous individuals results in the appearance of the color known as phenotypic characters and the genes that are involved known as genotypic characters.
-According to the question, the trait is the color of the flower, the dominant trait is red color and the recessive trait is white color.
