Which of the following is not considered simple Mendelian genetics?
A. recessive/dominant traits
B. law of segregation
C. polygenic inheritance
D. law of independent assortment
Answers
The correct answer is OPTION C: Polygenic Inheritance.
- The inheritance of features determined by a single gene with two alleles, one of which may be dominant over the other, is known as simple or Mendelian inheritance.
- Simple features controlled by genes on autosomes or sex chromosomes dictate the pattern of inheritance.
- Mendel proposed the first-generation characteristic inheritance law.
- Segregation, independent assortment, and dominance are the three laws that control inheritance.
Answer:
A) The recessive/dominant traits is not considered simple Mendelian genetics.
Explanation:
The key principles of Mendelian inheritance are summed up by Mendel's three laws:
The Law of Independent Assortment: According to the law of independent assortment, genes for different traits segregate independently. It means that different features are inherited in different ways. This is due to the fact that during meiosis, chromosomes line up at random before the cell divides, allowing for the production of gametes.
Law of Dominance: There are dominant and recessive qualities, according to the law of dominance. Dominant traits are defined as the phenotype that is expressed in a heterozygous organism for the trait.
and Law of Segregation: According to the law of segregation, everyone has two versions of each trait, one from each parent, and these alleles segregate randomly during meiosis.
