Answer 1

Characteristics from parents

Question 2

Who was the first person that tested genetics

Answer 2

Gregor Mendel

Question 3

Did Gregor first have to do with the pea pant

Answer 3

He had to override self pollination

Question 4

How did Gregor override self pollination in the P plant

Answer 4

He did this by cross pollination

Question 5

What did he receive when he began taking care of the garden

Answer 5

Purebred P seeds

Question 6

What happen with Mendel crossed pollinated the purebred plants and looked at the traits

Answer 6

He had created hybrids

Question 7

What did Mendel expect to find

Answer 7

Blending

Question 8

What did Mendel find

Answer 8

Dominant and recessive

Question 9

What were the two conclusions that Mendel drew

Answer 9

1. Individual factors control the tree of the organisms

2. Dominance principal

Question 10

What are controlling factor is called

Answer 10

Genes

Question 11

What is a gene

Answer 11

A length of DNA that codes for a particular trait

Question 12

What are contrasting forms of genes called

Answer 12

Alleles

Question 13

What are alleles

Answer 13

Contrasting forms of genes

Question 14

What is the length of DNA that codes for a particular trait

Answer 14

Genes

Question 15

What is the P generation

Answer 15

Parents

Question 16

F1 generation

Filial

Answer 16

First filial generation of offspring of distinctly different parents

Question 17

F2 generation

Filial

Answer 17

The filial generation comprised of offspring resulting from the mating of two members of fist filial generations

Question 18

Define linked genes

Answer 18

Genes on a chromosome are inherited together

Question 19

Define linkage groups

Answer 19

Packages of jeans that I always tended to be inherited together

Question 20

Define recombinant

Answer 20

Individuals with new combinations of jeans

Question 21

Define sex chromosomes

Answer 21

Seemingly mismatched chromosomes

Question 22

Define autosomes

Answer 22

Chromosomes that are the same between both male and female

Question 23

Define sex linked

Answer 23

A gene located on one of the sex chromosomes

Question 24

What are hybrids

Answer 24

Organisms produced by crossing parents with a different traits

Question 25

What is The first conclusion

Answer 25

Individual factors control the traits of organism - genes: control traits - alleles: contrasting forms of genes

Question 26

What is the second conclusion

Answer 26

Dominance principal

Question 27

Dominant allele

Answer 27

Always expressed and hides other (represented by capital letters)

Question 28

Recessive allele

Answer 28

Only expressed when a dominant gene is not present (represented by lower case letters)

Question 29

Define haploid

Answer 29

Cell with single set of unpaired chromosomes

Question 30

Define gamete

Answer 30

Mature haploid cell ready to fuse with another mature haploid cell

Question 31

Define zygotes

Answer 31

Diploid cell composed from the fusion of two haploid cells

Question 32

What is a cell with single set of unpaired chromosomes

Answer 32

Haploid

Question 33

What is a mature haploid cell ready to fuse with another mature haploid cell

Answer 33

Gamete

Question 34

What is a diploid cell composed from the fusion of two haploid cells

Answer 34

Zygotes

Question 35

What is the law of segregation

Answer 35

States that allele pairs separate or segregate during gamete formation and randomly unite at fertilization

Question 36

Genotype

Answer 36

The genetic constitution of an individual organism

Question 37

Phenotype

Answer 37

Characteristics of an individual resulting from the he interaction of its genotype with the environment

Question 38

What is independent assortment related to gamete formation

Answer 38

When the two factors for each trait are segregated during the formation of gametes
