are passed from
parent to offspring

Answer 4

Genetics

Question 5

Genetic is a field
of study that deals
with ____

Answer 5

heredity.

Question 6

are DNA molecules that
determine the traits of
the organisms.
ex. hair / height

Answer 6

GENES

Question 7

These are the genes that are
found in the same look of
homologous chromosomes.
Or these are the different
forms of a gene.

Answer 7

ALLELES

Question 8

The totality of all the
genotypes for all the
traits of an organism.

Answer 8

GENOME

Question 9

Gene that prevents the other gene from “showing”

Answer 9

dominant

Question 10

Gene that does NOT “show” even though it is present

Answer 10

recessive

Question 11

Both genes of a pair are the same

Answer 11

homozygous or
purebreed

Question 12

One dominant and one recessive gene

Answer 12

heterozygous or
hybrid

Question 13

Combination of genes an organism has

Answer 13

genotype

Question 14

Physical appearance resulting from gene makeup

Answer 14

phenotype

Question 15

Used to predict the possible gene makeup of offspring

Answer 15

Punnett Square

Question 16

states that genes are in a linear fashion on chromosomes and that the relative positions of genes can be determined by their frequency in the offspring through mating.

Answer 16

chromosomal theory of inheritance

Question 17

this area deals with the chromosomal theory of inheritance

Answer 17

Classical Genetics

Question 18

is the study of genetic material; its structure, replication, and
expression.

Answer 18

Molecular Genetics

Question 19

the mechanisms of evolutionary
change, the changes in frequencies in populations.

Answer 19

Evolutionary Genetics

Question 20

• The Father of Modern Genetics

Answer 20

Gregor Johann Mendel

Question 21

discovered the basic principles of heredity
through experiments in his monastery’s garden.

Question 22

This law states that all the genes for all the traits of an organism are
equally divided and are equally distributed in all the resulting
gametes after meiosis.

Answer 22

Law of Segregation

Question 23

This law states that alleles of different genes are distributed randomly to the gametes and fertilization occurs at random.

Answer 23

Law of Independent Assortment

Question 24

Only dominant trait is expressed

Answer 24

Law of Complete Dominance

Question 25

mix of heterozygous genes
ex. red flower + white flower = pink flower

Answer 25

Law of Incomplete dominance

Question 26

both dominant and recessive trait is expressed

Answer 26

Law of Co-dominance

Question 27

sex chromosomes of female

Answer 27

XX

Question 28

sex chromosomes of male

Answer 28

XY

Question 29

a gene responsible for a specific trait is
located on a sex chromosome, resulting in sexually dependent
inheritance of the trait.

Answer 29

Sex Linkage

Question 30

_ linked alleles always show
up in males whether
dominant or recessive
because males have only
one X chromosome

Answer 30

X

Question 31

Genes for these traits are
located only on the _
chromosome

Answer 31

X
