Non-Mendelian Genetics Overview

Front

What is codominance?

Back

A genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

What does a pedigree chart represent?

Back

A diagram that shows the occurrence and appearance of phenotypes of a particular gene or organism and its ancestors.

Front

What is the diploid number in human cells?

Back

46, which means humans have 23 pairs of chromosomes.

Front

How many phenotypes are there in ABO blood types?

Back

4 phenotypes: A, B, AB, and O.

Front

What is incomplete dominance?

Back

A genetic situation where one allele does not completely dominate another allele, resulting in a new phenotype.

Front

What is polygenic inheritance?

Back

A type of inheritance where multiple genes determine a single trait, leading to a wide range of phenotypes.

Front

What is a karyotype?

Back

A visual representation of an individual's complete set of chromosomes, organized by size and shape.

Front

What is sex-linked inheritance?

Back

A type of inheritance where genes are located on sex chromosomes, often affecting traits differently in males and females.

Front

What is a phenotype?

Back

The observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is a genotype?

Back

The genetic constitution of an individual, representing the alleles inherited from both parents.
