• A karyotype chart represents the image of an individuals chromosome
• Chromosomal map represents the genes present in a chromosome
• Hemoglobin is a protein present in red blood cell
• Pedigree chart is a tool used to analyze the passage of traits between generations

Which chromosome is affected by hemophilia?

• Hemophilia is a blood disorder
• Individual with hemophilia does not posses clotting factor VIII or IX
• The genes for producing clotting factors are present in X chromosome

What is the name of the protein that is not normal in people with sickle-cell disease?

• Red blood cells contain a protein called hemoglobin
• Sickle cell anemia patients will posses abnormal "S" hemoglobin
• Clotting factors are present in plasma

Which disorder or disease has alleles that are co-dominant with each other?

• Sickle cell disease is a medical condition where the Red Blood Cells loses its normal shape 
• The disease can be caused due to malaria or due to genetic disorder

Which disease or disorder is the result of having an extra chromosome?

• Down syndrome is also termed as trisomy 21
• Individuals posses an extra chromosome at 21 position
• Trisomy 21 is caused due to improper separation of chromosomes during meiosis
• Cystic fibrosis is an autosomal recessive disorder
• Color blindness is an autosomal dominant disorder
• Hemophilia is a monogenic genetic disorder

Which disease or disorder is caused by the inheritance of two mutated alleles?

• Cystic fibrosis results in breathing disorder of the affected individual due to increased thick mucus secretion
• The disorder is caused due to alteration in CFRT gene
• It is a type of autosomal recessive disorder, having both copies of gene altered in a cell
• Other disorders mentioned are not autosomal recessive in nature

Which of the following is NOT caused by a gene mutation?

it is an example of chromosomal disorder.

Which of the following is NOT a chromosomal disorder?

others are example of chromosomal disorders.

Which of the following is a sex-linked disorder?

it is a sex-linked recessive disorder.
The abnormal gene responsible for hemophilia a carried on the X chromosome.

Which of the following has normal sex chromosomes?

it occurs due to an extra autosome hence, sex chromosomes are not affected.

gregor mendel discovered the law of heredity.

A gamete contains which of the following?

each gamete receives single allele of a gene.

All types of mutations are transferable among generations.

Germ-line mutations occur in gametes which can be inherited while, somatic mutations cannot be inherited.
