Question 5

Sex linked

example

Answer 5

Genes that are carried by either sex chromosome

Hemophilia is an X linked trait

Question 6

Polygenic

example

Answer 6

Many genes that control a single trait

Height, skin color, etc…

Question 7

Intermediate inheritance is also called?

Answer 7

Incomplete dominance (red+white=pink)

Question 8

The principle of independent assortment

Answer 8

Each pair of alleles are separated independently and are not inherited together

Question 9

What is the principle of segregation?

Answer 9

Each organism had 2 alleles for a gene. Only 1 allele from each gens will be inherited by the offspring

Question 10

What’s a gene? An allele?

Answer 10

Allele: alternate form of a gene
Gene: a use of heredity (combo of alleles) that is transferred from patent to offspring (determine characteristics)

Question 11

On a Cladogram, whats going to be most closely related to one another? The first two animals or the last two?

Answer 11

Last two

Question 12

Homologous structure

Answer 12

Same structure, different function

forelimb of an animal

Question 13

Analogous structure

Answer 13

Same function, different structure

bird/bug wing
((does not prove evolution))

Question 14

Molecular evidence for evolution?

Answer 14

DNA sequence

Question 15

Gene pool

Answer 15

All copies of a gene that exists in a population

Question 16

What are Multiple alleles?

example

Answer 16

Several alleles, 1 trait

Blood types

Question 17

If disruptive selection is occurring, which individuals are more likely to survive?

Answer 17

Ones with extreme traits

Question 18

The DNA sequence in 3 different organisms is almost exactly the same. This is an example of…?

Answer 18

Molecular homologies

Question 19

How does artificial selection produce rapid changes in the phenotype of an organism?

Answer 19

By changing the allele frequency and selecting for new traits

Question 20

If a homozygous tall plant and a homozygous short pea plant crossed…?

Answer 20

The recessive trait would seem to disappear

Question 21

Organisms that have 2 identical alleles for a particular trait are said to be…?

Answer 21

Homozygous

Question 22

The phenotype of an organism is determined by…?

Answer 22

It’s environment AND phenotype

Question 23

A trait controlled by many genes is called…?

Answer 23

Polygenic inheritance
