Question 1

Allele

types of genes, mostly traits

Question 2

Heterozygous

Answer 2

having two different alleles for a given gene on the homologous chromosome
Bb

Question 3

Homozygous

Answer 3

having two identical alleles for a given gene on the homologous chromosome
BB or bb

Question 4

Trait

Answer 4

variation in the physical appearance of a heritable characteristic

Question 5

Dihybird

Answer 5

result of a cross between two true-breeding parents that express different traits for two characteristics

Question 6

Co-dominance

Answer 6

expression of both alleles, shown in physical form.

Question 7

Incomplete dominance

Answer 7

expression of two contrasting alleles such that the individual displays an intermediate phenotype. A blending

Question 8

Monohybrid

Answer 8

result of a cross between two true-breeding parents that express different traits for only one characteristic

Question 9

Sex linked

Answer 9

any gene on a chromosome, through X or Y

Question 10

Punnett Square

Answer 10

visual representation of a cross between two individuals in which the gametes of each individual are denoted along the top and side of a grid

Question 11

Genetics

Answer 11

the study of heredity

Question 12

What is the difference between Dominate & Recessive?

Answer 12

Dominant will mask the recessive. But if dominant is not present the recessive will be present.

Question 13

What is the difference between genotype and phenotype?

Answer 13

Genotype is you DNA(what gene you have). Phenotype is what you look like, what you can see.

Question 14

Polygenic Inheritance

Answer 14

height, weight, and intelligence.

Question 15

Medel segregation

Answer 15

contains two factors for each trait. Each gamete will contain only one factor for that trait.

Question 16

Medel Independent

Answer 16

shown by examine a cross involving two traits (a dihybrid cross)
