Genes consisting of DNA ar the blueprint of heritable information that determine human attributes and individual traits. The expression of genes codes for specific functions. Genes have alternate forms known as alleles which are transmitted to offspring. If the two alleles are different then there is a hybrid at F 1 generation. The dominant allele out of the two alleles expresses itself and determines the phenotype .

Question

Chapter 10, Problem 1SQ

Summary Introduction

Concept introduction: Genes consisting of DNA ar the blueprint of heritable information that determine human attributes and individual traits. The expression of genes codes for specific functions. Genes have alternate forms known as alleles which are transmitted to offspring. If the two alleles are different then there is a hybrid at F₁ generation. The dominant allele out of the two alleles expresses itself and determines the phenotype.

Expert Solution & Answer

Answer to Problem 1SQ

Correct answer: Genes commonly exert their effect on a phenotype by coding for protein. Hence, option c. is correct answer.

Explanation of Solution

Reasons for the correct statement:

Option c. is given as, “coding for protein”. Genes are DNA sequences which code for specific traits. The specific position of a gene on a chromosome is known as locus. Genes are transcribed to form mRNA that carries genetic information. mRNA is then translated to protein. Thus, the gene is expressed in the form of protein and exerts their effect on phenotype of an individual. Hence, option c. is correct answer.

Reasons for incorrect statements:

Option a. is given as “promoting DNA mutations”. Genes are expressed in the form of proteins that exert their effect on phenotype of an individual not by promoting DNA mutations. Hence, option a. is incorrect.

Option b. is given as “creating chromosomal structures such as centromeres”. Genes are expressed in the form of proteins that exert their effect on phenotype of an individual not by creating chromosomal structures. Hence, option b. is incorrect.

Option d. is given as “all of the above”. Genes are expressed in the form of proteins that exert their effect on phenotype of an individual not by DNA mutations or by creating chromosomal structures. Hence, option d. is incorrect.

Hence, options a., b., and d. are incorrect.

Conclusion

Genes exert their effect on phenotype by coding for protein.
