Question 1

Gene

Answer 1

Inherited Factor that determines a characteristic

Question 2

Allele

Answer 2

One or two more alternative forms of a gene

Question 3

Locus

Answer 3

Specific place on a chromosome occupied by an allele

Question 4

Genotype

Answer 4

Set of alleles passed by an individual organism

Question 5

Heterozygote

Answer 5

An individual possessing two different alleles at a locus

Question 6

Homozygote

Answer 6

an individual possessing two of the same alleles at a locus

Question 7

Phenotype

Answer 7

The appearance or manifestation of a character

Question 8

Monohybrid cross

Answer 8

Cross between parents differed in a single characteristic

Question 9

Reciprocal Cross

Answer 9

Crossing two parents of different traits

eg. wrinkly vs smooth

Question 10

Dominant

Answer 10

If there, trait will be expressed (not always most common trait)

Question 11

Recessive

Answer 11

Trait will only be expressed if two of them are together

Question 12

Mendel’s First Law of Segregation

Answer 12

Each individual posseses two alleles coding for a trait. These separate when gametes are formed and alleles separate in equal proportions

Question 13

Independent Assortment/Mendel’s 2nd Law

Answer 13

alleles at different loci separate independently

Question 14

Test Cross

Answer 14

an individual of unknown genotype is crossed with another individual with a homozygous recessive genotype

Question 15

Wild Type

Answer 15

Common allele for a character

Question 16

Di-hybrid Cross

Answer 16

Cross between 2 different traits

ex: wrinkled &yellow X round &green
