Miscellaneous
100
Gregor Mendel did this to pea plants to study different characteristics
What is CROSS-POLINATION
100
An organism's physical appearance is called this.
What is a phenotype?
100

Any change in the DNA sequence that can alter the genetic code.

What is a genetic alteration?

100
Any change in a gene or chromosome is called this.
What is a mutation?
200
Mendel used T to show the dominant allele for height, meaning tall. He used this letter to show the recessive allele.
What is t
200
This is the term that refers to the physical characteristics that are studied in genetics.
What is a trait?
200

They are alterations in the nucleic acid sequence of the genome of an organism.

What are mutations?

200
This nitrogen base is in RNA but NOT in DNA.
What is uracil?
300
The notation TT or AA to a geneticist means there are this many dominant alleles in a genotype.
What is 2 (two)
300
An organism's genetic type is called this.
What is a genotype?
300

It is a physical, chemical or biological agent that permanently changes genetic material in an organism and increases the frequency of mutations

What is a mutagen?

300
An organism that has two identical alleles for a trait is called this.
What is homozygous
400
This is the probability of producing a tall pea plant from a genetic cross between two hybrid tall pea plants
What is 50% (or two in four)
400
Two different forms of a gene are called this.
What are alleles?
400

It is a health problem caused by one or more abnormalities in the genome. It can be caused by a mutation in a single gene (monogenic) or multiple genes (polygenic) or by a chromosome abnormality.

What is a genetic disorder?

400
If this type of allele is present, its trait will appear in the organism.
What is dominant?
500
Gregor Mendel, in addition to studying pea plants, was this religious leader.
What is a priest?
500
An organism with two different alleles is called this.
What is a hybrid?
500

The may result from genetic or chromosomal disorders, exposure to certain medications or chemicals, or certain infections during pregnancy.

What causes congenital malformations?

500
Genes are carried from the parent to the offspring on structures called this.
What are chromosomes?
