Question 1

Allele

Answer 1

different version of the same gene

Question 2

Austrian monk- used pea plants to learn abt genetics
“Father of Genetics”
-3 laws of inheritance

Question 3

3 Laws of Inheritance

Answer 3

-Law of Dominance
-Law of Segregation
-Law of Independent Assortment

Question 4

Cross

Answer 4

making of 2 organisms
-P: Parental Gen
-F1: First Gen
-F2: Second Gen

Question 5

Homozygous

Answer 5

2 of the same alleles

Question 6

Heterozygous

Answer 6

2 different alleles

Question 7

Law of Dominance

Answer 7

a dominant allele will express itself over a recessive allele

Question 8

Dominant

Answer 8

if present, allele will always have the trait expressed

Question 9

Recessive

Answer 9

allele will only have that trait expressed when the dominant allele is not present

Question 10

Genotype

Answer 10

the actual alleles inherited (FF, Ff, ff)

Question 11

Phenotype

Answer 11

the physical traits seen in an organism (purple flowers, blue eyes)

Question 12

Law of Segregation

Answer 12

when chromosomes separate in meiosis, each gamete will receive only one chromosome from each pair

Question 13

Law of Independent Assortment

Answer 13

the assortment of chromosomes for one trait doesn’t affect the assortment of chromosomes for another trait
-allows for any combo of maternal + paternal chromosomes to be passed on
