“10th Class Biology Chapter 15 Quiz: Inheritance” explains the very basics of heredity and how traits are passed from one generation to the next. This chapter is very important for MDCAT students since it provides a base for understanding genetic principles, which become vital in many medical and dental topics. Our MDCAT Quiz for this chapter will help you test and solidify your understanding of inheritance patterns and genetic mechanisms.
This will begin with the basic concept of inheritance—how traits are inherited through the genes from parents to offspring. Students will learn about the work of Gregor Mendel, often considered the father of modern genetics, and his experiments with pea plants that led to the discovery of the laws of inheritance. These include the Law of Segregation and the Law of Independent Assortment. The chapter continues with an explanation of dominant and recessive traits, using Punnett squares to predict the genetic outcomes of crosses. Students will learn about genotype—the genetic makeup—and phenotype—observable traits—and how these relate to each other and are affected by the alleles. This chapter also includes Mendelian inheritance, including complete dominance, co-dominance, and incomplete dominance, along with sex-linked inheritance, which deals with traits carried on the X and Y chromosomes.

Which scientist proposed the theory of inheritance through the transmission of acquired characteristics?

In a Punnett square, what represents the possible genotypes produced by the union of gametes?
Intersections
Which law states that each pair of alleles segregates independently of other pairs during gamete formation?
Law of Independent Assortment
Which genetic disorder is characterized by the absence of an enzyme needed to break down lipids, leading to the accumulation of fatty substances in the brain?
Tay-Sachs disease
What is the expected phenotypic ratio in the F2 generation of a dihybrid cross between two heterozygous individuals?
9:3:3:1
In a test cross, what is the purpose of crossing an individual with an unknown genotype with a homozygous recessive individual?
To determine the genotype of the unknown individual
Which genetic disorder results from the inability to produce melanin, leading to a lack of pigmentation in the skin, hair, and eyes?
Albinism
Which scientist discovered the principle of genetic linkage by studying fruit flies?
Thomas Hunt Morgan
What is the probability of having a child with a dominant genetic disorder if both parents are affected (homozygous)?
0.5
What is the term for an individual who carries one copy of a recessive allele for a genetic disorder but does not express the trait?
Carrier

Which scientist is known as the "father of modern genetics" for his work on the inheritance of traits in pea plants?
Gregor Mendel
In codominance, what is the result when two different alleles for a gene are both expressed in the heterozygous condition?
Both traits are fully expressed
Which genetic disorder is caused by the absence of an enzyme needed to break down phenylalanine?
Phenylketonuria (PKU)
