Practice Quiz For Mendels Genetics True False Questions - Quiz

Check out our informative practice quiz for Mendel's genetics to test your knowledge about Mendelian genetics law. The quiz consists of true and false questions. Gregor John Mendel developed three inheritance principles that follow that heredity is the result of discrete units of inheritance. You can learn more about Mendel's law of inheritance by playing the quiz below.
In this quiz, you'll explore Mendel's key experiments with pea plants, understand the significance of dominant and recessive traits, and grasp how these principles laid the groundwork for modern genetics. Perfect for students, teachers, and anyone interested in biology, this Read morequiz will challenge your understanding and deepen your appreciation for Mendel's contributions. Good luck.

Mendel's Genetics Questions and Answers

1.

Genetics is the study of biologically inherited traits determined by elements of heredity that are transmitted from offspring to Parents in reproduction.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Genetics is the study of biologically inherited traits determined by elements of heredity that are transmitted from parents to offspring in reproduction, not the other way around.

2.

Inherited elements are called genes.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Inherited elements refer to the genetic material passed down from parents to offspring. These elements are known as genes and they determine various traits and characteristics of an individual. Therefore, the statement "inherited elements are called genes" is true. Genes play a crucial role in the transmission of hereditary information and are responsible for the diversity and continuity of life.

3.

The latest advance in the study of the chemical nature of genes and the ways that genes function to affect certain traits is called genomic.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The given statement is true. Genomics refers to the study of the structure, function, and mapping of an organism's complete set of DNA, including all of its genes. It involves analyzing the entire genome, including the interactions between genes and their environment, to understand how genes function and influence traits. This field has made significant advancements in understanding the chemical nature of genes and their role in determining various traits. Therefore, the statement is correct.

Mendel picked common garden pea because pea plants have both male and female reproductive organs.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Mendel chose common garden pea as his experimental plant because it has both male and female reproductive organs. This allowed him to easily control and manipulate the breeding process, ensuring that he could cross-pollinate specific plants with desired traits. By doing so, Mendel was able to study the inheritance patterns of these traits and establish the foundation of modern genetics.

5.

Mendel observed that the flower color is purple or white.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Mendel observed that flower color is not limited to just purple or white. He discovered that there are actually a variety of flower colors, including yellow and green, which can be inherited through genetic factors. Therefore, the statement that the flower color is only purple or white is false.

6.

Medical genetics involves any application of genetic to medical practice.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Medical genetics is the branch of genetics that involves the study and application of genetics to medical practice. It encompasses the diagnosis, prevention, and treatment of genetic disorders, as well as the understanding of how genes contribute to human health and disease. Therefore, it is true that medical genetics involves the application of genetics to medical practice.

Rate this question:
7.

Multifactorial disorders are one of the genetic disorder types.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Multifactorial disorders are indeed one of the types of genetic disorders. Unlike single gene disorders, multifactorial disorders are caused by a combination of genetic factors as well as environmental factors. These disorders are influenced by multiple genes, each contributing a small effect, along with various environmental factors such as diet, lifestyle, and exposure to toxins. Examples of multifactorial disorders include heart disease, diabetes, and certain types of cancer. Therefore, the statement "multifactorial disorders are one of the genetic disorder types" is true.

8.

Heart disease and diabetes are single gene disorder.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Heart disease and diabetes are not single gene disorders. Both conditions are complex diseases that are influenced by a combination of genetic, environmental, and lifestyle factors. Multiple genes are involved in the development of these diseases, and their interaction with other factors determines an individual's risk. Therefore, it is incorrect to classify heart disease and diabetes as single gene disorders.

Rate this question:
9.

Allele is a variant form of gene.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The statement "Allele is a variant form of gene" is true. An allele refers to one of the possible forms of a gene, which can differ in their DNA sequence. Genes are made up of DNA and they determine specific traits or characteristics in an organism. Each gene can have multiple alleles, and these different forms can result in variations in the traits or characteristics expressed by an organism. Therefore, the statement accurately describes the relationship between alleles and genes.

Rate this question:
10.

Autosome is body chromosome.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The statement is true because autosomes are chromosomes that are not involved in determining an individual's sex. They are responsible for carrying genetic information related to the individual's characteristics and traits. In humans, autosomes are numbered from 1 to 22, while the sex chromosomes are X and Y. Therefore, the statement accurately states that autosomes are body chromosomes.

11.

Recessive allele: TT
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The given answer is false because a recessive allele is represented by a lowercase letter, not an uppercase letter. In this case, "TT" represents a dominant allele, not a recessive allele.
