Normally each cell in humans has 46 chromosomes (23 pairs). Twenty-two pairs of chromosomes are autosomes and one pair is sex chromosome (X and Y). Any variations in chromosomal arrangements leading to defects can be identified by karyotyping, pedigree analysis, and DNA sequencing.

Summary Introduction

Introduction: Normally each cell in humans has 46 chromosomes (23 pairs). Twenty-two pairs of chromosomes are autosomes and one pair is sex chromosome (X and Y). Any variations in chromosomal arrangements leading to defects can be identified by karyotyping, pedigree analysis, and DNA sequencing.

Expert Solution & Answer

Answer to Problem 1TYU

Correct answer: A diagram of pedigree shows the expression of genetic traits in the members of two or more generations of a family. Hence, the correct answer is Option (e).

Explanation of Solution

Reason for the correct answer:

Option (e) is given as “the expression of genetic traits in the members of two or more generations of a family”. Pedigree represents the genetic family history to determine the risk or presence of a disease in the next generation. It is referred as a family tree that is drawn by tracing the history of variant phenotypes using certain symbols. It consists of shapes and lines that represent gender marriage and descendants. It can predict the occurrence of a disease in the next generations.

Hence, the correct answer is Option (e).

Reasons for incorrect answers:

Option (a) is given as, “controlled matings between members of different true-breeding strains”. This is referred as a monohybrid cross. Hence, Option (a) is incorrect.

Option (b) is given as, “the total genetic information in human cells”. Chromosomes, genes, and DNA constitute the total genetic information. A pedigree is formed based on the phenotypic variations in a gene or an organism from one generation to next generations. Hence, Option (b) is incorrect.

Option (c) is given as, “a comparison of DNA sequences among the genomes of humans and other species”. This is referred as a study of comparative genomics. A pedigree does not compare the genomes of different species. Hence, Option (c) is incorrect.

Option (d) is given as, “the subtle genetic differences among unrelated people”. A pedigree is formed based on the phenotypic variations in a gene or an organism from one generation to next generations. It does not relate to genotypic variations. Hence, Option (d) is incorrect.

Hence, Options (a), (b), (c), and (d) are incorrect.

Conclusion

A pedigree shows the expression of genetic traits among two or more generations of a family.
