Final Jeopardy

3 basic methods used by ecologists to study the

living world

What are observing, experimenting, and modeling?

$200

What is genetics?

Scientific study of heredity.

$400

What is true-breeding?

Same as self-pollination.

$600

What are genes?

Chemical factors that determine traits.

$800

What are alleles?

Term for different forms of genes.

$1000

What are phenotype & genotype?

Two terms: 1st term represents your

physical characteristics. 2nd

term represents your genetic makeup.

$200

What is dominant?

Traits that can be seen are considered to be

this.

$400

What is recessive?

Traits that are hidden until 2 come together.

$600

What is homozygous?

These two genotypes TT & tt are considered this.

$800

What is with a capital letter and lowercase

letter; Tt?Only one way to

represent a heterozygous genotype.

$1000

What is hybrid?

Offspring crosses between parents with different traits.

$200

Who is Gregor Mendel?

He developed many principles of genetics over the course of his

research.

$400

What is the Principle of Dominance?

Some alleles are dominant and other alleles are recessive.

$600

What is the Principle of Heredity?

Traits are passed from one generation

to the next.

$800

What is probability?

The likelihood that a specific event will

occur.

$1000

What is the Principle of Independent Assortment?

Genes for different traits are passed

independently of one another.

$200

What are all organisms?

Mendel’s principles of genetics apply to

which of the following: plants only,

animals only, or all organisms.

$400

What is a permanent change in the DNA

sequence of a gene?

A mutation is this.

$600

What are UV rays, asbestos, tars from

tobacco?

These are 2 example of mutagens.

$800

What are hybrid and heterozygous?

2 terms that are the opposite of

homozygous

$1000

What is the P generation?

The plants Mendel crossed to produce the F1 generation made up

this generation.

$200

What is B=big eyes, b=small eyes?

Big eyes are dominant to small…this letter is used to represent big eyes and this letter is

used to represent small eyes

$400

What are LL, Ll, & ll?

In Martian’s, large heads are dominant to small.

These are all of the possible genotypes a

Martian could be.

$600

What is Large ears?

In Martian’s, small ears are recessive to large ears. What is the phenotype for a Martian who is LL

$800What are BB or Bb?

Knowing that blue eyes are recessive,

these are the possible genotypes for a

person w/brown eyes

$1000

What pure-breeding and self-fertilized/pure-bred?

These are two synonyms for homozygous.

$200

What is homozygous?

Organisms that have 2 identical alleles for a particular trait are

said to be this.

$400

What are the genotypes of the

offspring?A Punnett square is

only able to show you these.

$600

What are two combinations; RY &

rY?This many different allele combinations

can be produced from a genotype of RrYY.

$800

What is incomplete dominance?

Situation in which one allele for a gene is NOT completely dominant

over another allele for that gene.

$1000

What is codominance?

Crossing a black chicken BB, with a white chicken WW produces speckled offspring demonstrates

this.
