HUMAN GENETICS: PEDIGREES

Front

Chromosome that is not a sex chromosome

Back

Autosome: A chromosome that is not involved in determining the sex of an individual.

Front

In humans, the 23rd pair of chromosomes are called:

Back

Sex chromosomes: The chromosomes that determine the biological sex of an individual, consisting of XX for females and XY for males.

Front

Chart that shows the relationships within a family

Back

Pedigree: A diagram that depicts the biological relationships between individuals in a family, often used to track genetic traits.

Front

This is an example of what? (referring to inheritance patterns)

Back

Incomplete dominance: A genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype.

Front

In the second generation-how many people have the disease or display the physical trait?

Back

2: Refers to the number of individuals in the second generation of a pedigree who exhibit a specific trait or disease.

Front

What is the function of autosomes?

Back

Autosomes carry the majority of an individual's genetic information, excluding sex-linked traits.

Front

What are sex chromosomes responsible for?

Back

Sex chromosomes determine the sex of an individual and carry genes related to sexual development.

Front

Define pedigree analysis.

Back

Pedigree analysis is a method used to study the inheritance of traits in families, helping to identify patterns of genetic disorders.

Front

What is complete dominance?

Back

Complete dominance occurs when one allele completely masks the effect of another allele in a heterozygous genotype.

Front

What is codominance?

Back

Codominance is a genetic scenario where both alleles in a heterozygote are fully expressed, resulting in a phenotype that shows both traits.
