Question 0

Trait

Answer 0

A variation of a particular characteristic

Question 1

Heredity

Answer 1

How traits are passed from parents to offspring

Question 2

Blending hypothesis

Answer 2

Offsprings trait is a blend of parents traits, genetic studies later disapproved this theory

Question 3

particulate hypothesis

Answer 3

Parents pass on factors to offspring that determine traits, these jeans retain their ideal generation after generation

Question 4

Self fertilization

Answer 4

Pollen from a flower on a single plant used to fertilize a flower on the same plant

Question 5

Cross-fertilization

Answer 5

Pollen from one plant fertilizes another

Question 6

P generation

Answer 6

True breeding parent plants

Question 7

F one generation

Answer 7

First generation of offspring, hybrids

Question 8

Hybrids

Answer 8

First generation of offspring also known as the F1 generation

Question 9

Mono hybrid crosses

Answer 9

Breed two plants that only differ in one trait

Question 10

Alleles

Answer 10

Alternative forms of genes

Question 11

Homozygous

Answer 11

both same allele

Question 12

Heterozygous

Answer 12

One allele of each type

Question 13

Dominant

Answer 13

Affects the trait in a heterozygous individual, allele written as capital letter

Question 14

Recessive

Answer 14

Does not appear to affect the trait, lowercase same letter

Question 15

Principle of segregation of alleles

Answer 15

Two alleles of a trait separate when a parent forms gametes

Question 16

phenotype

Answer 16

Observable trait

Question 17

Genotype

Answer 17

Genetic, combo of alleles

Question 18

Test cross

Answer 18

An organism with dominant phenotype could be home not homozygous dominant or heterozygous, use a test cross to determine the genotype, breed unknown genotype plans with homozygous recessive plant

Question 19

Dihybrid cross

Answer 19

Some of Mandel’s experiments crossed plants that differed in two characteristics
