Lab 11 Genetics

Question 1

Who discovered the pattern of inheritance of organisms?

Answer 1

Gregor Mendel

Question 2

Phenotype

Answer 2

physical characteristics of a gene; i.e. dark hair

Question 3

Genotype

Answer 3

The actual alleles which makes up an organisms genome; Aa or aa

Question 4

Portions of the chromosomes that contain information to build proteins

Answer 4

Genes

Question 5

Alleles

Answer 5

Variations in genes

Question 6

Are most animals haploid or diploid?

Answer 6

Diploid

Question 7

Homozygous

Answer 7

Genotype where organisms have the same alleles for a particular gene

Question 8

Heterozygous

Answer 8

Genotype where organisms have different alleles

Question 9

Dominant Allele

Answer 9

Alleles which express themselves if there is 1 or 2 copies of the alleles

Question 10

Recessive Alleles

Answer 10

Alleles which only express if there are 2 copies of the recessive allele present

Question 11

Incomplete Dominance

Answer 11

When an intermediate phenotype is the result of 2 different alleles

Question 12

Codominance

Answer 12

When 2 alleles express themselves

Question 13

Device used to demonstrate the probabilities of potential offspring

Answer 13

Punnett Square

Question 14

Monohybrid Cross

Answer 14

A cross while tracking one gene

Question 15

What is the genotypical ratio?

Answer 15

1:2:1

Question 16

What is the phenotypical ratio?

Answer 16

3:1

Question 17

Autosome Chromosome

Answer 17

Chromosomes which are not involved with gender identity

Question 18

Sex Chromosomes

Answer 18

Chromosomes involved with gender identity

Question 19

Sex-Linked Genes

Answer 19

Genes found on the X-Chromosome which are not involved with gender identity

Question 20

What type of chromosomes do females have?

Answer 20

XX - 2 X Chromosomes

Question 21

What type of chromosomes do males have?

Answer 21

XY

Question 22

Why do males only receive 1 set of sex linked genes?

Answer 22

Because the Y chromosome only contains information on being male
