Quiz 1 MiniStudyguide

Question 1

Structural Gene

Answer 1

Carry the information for the amino acid sequence for a polypeptide (protein)

Question 2

Morphological Trait

Answer 2

Affect the appearance, form, and structure of an organism

Question 3

Physiological Trait

Answer 3

affect the ability of an organism to function

Question 4

Behavioral Trait

Answer 4

Affect the ways an organism responds to its environment

Question 5

Genetic Approach

Answer 5

the study of mutant genes that have abnormal function. By studying mutant genes, researchers may better understand normal genes and normal biological processes

Question 6

Central Dogma of Genetics

Answer 6

The gene expression pathway from DNA to RNA to polypeptide (protein).

Question 7

Law of Segregation

Answer 7

two copies of a gene separate from each other during transmission from the parent to offspring

Question 8

Law of Independent Assortment

Answer 8

Two different genes will randomly assort their alleles during gamete formation

Question 9

Hybrid

Answer 9

Offspring obtained from two parents who have different features

Question 10

Particulate theory of inheritance

Answer 10

Traits are inherited as discrete units that remain unchanged as they are passed from parent to offspring

Question 11

Steps for a Punnett Square

Question 12

Homologous chromosomes similarities

Answer 12

Each has the same genes in the same order

Question 13

Homologous chromosomes differences

Answer 13

There may be variation between them resulting in different alleles

Question 14

What causes recessive phenotypes?

Answer 14

The individual must have two copies to be observed, one from each parent

Question 15

Inheritance patterns in autosomal dominant various observations

Answer 15

A single copy of the mutated gene is enough to cause the disorder (one parent)

Question 16

Inheritance patterns in autosomal recessive traits various observations

Answer 16

Two copies of the mutated gene are enough to cause the disorder (two parents)

Question 17

Pioneer of female reproductive biology

Answer 17

Walter Heape

Question 18

Molecular Genetics

Answer 18

examination of DNA structure and function at the molecular level

Question 19

Transmission Genetics

Answer 19

The inheritance of genes and the way that genes influence traits

Question 20

Population Genetics

Answer 20

primarily concerned with the extent of genetic variation within a group of individuals and changes in that variation over time

Question 21

What do low chi-square values imply

Answer 21

Little difference between what was observed and what was expected

Question 22

What do high chi-square values imply

Answer 22

There will most likely be a lot of difference between what is observed and what is expected

Question 23

Genes expressed at the molecular level

Answer 23

Gene transcription and translation lead to the production of a particular protein

Question 24

Genes expressed at the cellular level

Answer 24

the function of a protein within a cell affects the structure and working of that cell

Question 25

Genes expressed at the organism level

Answer 25

traits that we can observe through the human eye

Question 26

Genes expressed at population level

Answer 26

occurrence of a trait within a species
