Genetic Inheritance
100
Humans have 46 of these, arranged in 23 pairs.
What are chromosomes?
100
The condition where a person has three copies of chromosome 21 is known as this.
What is Down syndrome (trisomy-21)?
100
This term refers to the combination of two gametes, forming a new individual with 23 chromosomes from each parent.
What is a zygote?
100
This type of twin results from a single zygote that splits into two, sharing the same genotype.
What are monozygotic (identical) twins?
200
This is the term for a small section of a chromosome and is the basic unit for heredity.
What is a gene?
200
This genetic pattern involves a recessive gene carried on the X chromosome and is often passed from mother to son.
What is X-linked inheritance?
200
This scientific project, completed in 2003, mapped the entire human genetic code.
What is the Human Genome Project?
200
what is is represented here
what is sicklecell
300
This is the reproductive cell that contains 23 chromosomes.
What is a gamete?
300
This condition, where red blood cells become crescent-shaped, offers protection from malaria but can cause severe health issues when inherited.
What is sickle cell disease
300
genotype BB heterozygous or homozygous
homozygous
300
how environmental factors affect genes and genetic expression—enhancing, halting, shaping, or altering gene expression
what is epigenetics
400
This term describes the observable characteristics of an organism.
What is a phenotype?
400
This technique allows scientists to modify genes and potentially cure diseases but raises ethical concerns.
What is CRISPR?
400
This method involves fertilizing an egg outside a woman’s body and implanting it in the uterus.
What is In Vitro Fertilization (IVF)?
400
The field of study that focuses on how environmental factors influence gene expression.
What is epigenetics?
500
This molecule contains the chemical instructions for cells to manufacture proteins.
What is DNA?
500
If a trait is afected by many genes it is said to be
What is polygenic?
500
This term refers to a variant form of a gene.
What is an allele?
500
This X-linked disorder is passed from mother to son and affects blood clotting.
What is hemophilia?
