Answer: The correct answer for the blanks are-
1) In incomplete dominance
2) Pink carnation.
3) More than one.
4) 99.9 %
Incomplete dominance (also known as partial dominance) occurs when a dominant form of a gene does not completely masks the expression of another gene variant ( that is a recessive allele).
A heterozygote results in a blend of phenotype ( that lies between the phenotypes of two homozygous parents).
In this question, a red carnation with a white carnation will produce a pink carnation due to incomplete dominance.
When traits are controlled by more thgan one gene, they are called polygenic traits ( this conditon occurs most of the times). We humans exhibit different phenotypes due to differential expression of genes but genetically we all share 99.9 % similarity ( which relates to the genetical material).
Answer 1
Incomplete dominance,
Explanation
Incomplete dominance refers to a phenomenon in which alleles are not fully dominant over the other. In this way, a new phenotype is formed. This phenotype is a mixture or somewhere between the dominant or recessive phenotype. Shortly, this phenotype is a blend of both parents. This is the reason it has the features of both the parents as well as self-features that are created naturally.
Answer 2
White Carnation
Explanation
When red and white carnations are cross-pollinated, white carnation is produced. As red and white carnations are not dominant due to incomplete dominance. Incomplete dominance is the phenomenon in which neither allele is completely dominant over the other. That is the reason of it being white carnation in the living organism which is being discussed in the blank.
Answer 3
More than one gene
Explanation
Mostly more than one gene controls a trait. This phenomenon is called polygenic inheritance. Because an individual is formed by two parents, hence one allele comes from both parents for every trait. Example are human blood group, height, eye color, skin color and many more. These are the easiest possible example that could easily explain the gene control
Answer 4
99.9% similar
Explanation
With regards to genetic makeup, all humans have the same genes. We are genetically similar. Despite physical differences, all human populations are genetically similar. The 0.1 difference s due to the variation in the individuals from the same population. Though this ting difference is enough to find the ancestors of the individual, which usually indicates the background.
