module 8

Question 1

shows itself went to opposing characteristics are present

Answer 1

dominant gene

Question 2

is hidden unless two recessive genes are present

Answer 2

recessive gene

Question 3

allele

Answer 3

One pair of genes. ex. T or t

Question 4

genotype

Answer 4

to allele sets, the genes you actually have. TT, tt, Tt

Question 5

phenotype

Answer 5

what it looks like, Gene expressing itself

Question 6

diploid cells

Answer 6

cells with a full set of chromosomes

Question 7

haploid cells

Answer 7

sex cells with half sets of chromosomes

Question 8

sperm cell + ovum cell =

Answer 8

diploid cell

Question 9

Mono hybrid’s

Answer 9

combining one trait between two individuals

Question 10

pedigree

Answer 10

diagram that follows a phenotype through several generations

Question 11

dihybrid’s

Answer 11

combining two traits between two individuals

Question 12

autosomes

Answer 12

all chromosomes that do not determine the sex of an individual

Question 13

sex chromosomes

Answer 13

chromosomes that determine the sex of an individual

Question 14

sex linked trait’s

Answer 14

traits that only travel on the sex chromosome

Question 15

polygenetic inheritance

Answer 15

trait that results from several chromosome genes interacting

Question 16

incomplete dominance

Answer 16

neither allele is dominant so they blend together

Question 17

codominance

Answer 17

both alleles are present in equal strength

Question 18

Mendel’s four principles

Answer 18

traits determined by genes
2 alleles make up the genotype for a trait
each parent contribute one allele per trait to offspring
if a dominant gene is present it will be expressed

Question 19

antigen

Answer 19

protein jersey covering on your blood cells

Question 20

father of genetics

Answer 20

Gregor Mendel
