would most likely not have developed on its
own

Answer 10

Genetic Engineering

Question 11

only requires one person and normally it can split into two can make offspring without another parent.

Answer 11

Asexual reproduction

Question 12

two parents come together to make an offspring with egg and sperm.

Answer 12

sexual reproduction

Question 13

The trait that always will show up in the DNA

Answer 13

Dominant Trait

Question 14

They determine traits. A stretch of DNA on a chromosome with instructions for one trait. DNA contains this.

Answer 14

Genes

Question 15

Genes that have 2 identical alleles. Homo means the same (RR,rr)

Answer 15

Homozygous

Question 16

The physical characteristics of a trait, or what it looks like.

Answer 16

Phenotype

Question 17

Taking DNA from one organism and inserting
it into another organism’s DNA sequence to
ensure the organism will have a specific trait.

Answer 17

Genetic Engineering

Question 18

Can be performed easily by farmers &
breeders

Answer 18

Selective Breeding

Question 19

Identifying certain genes and moving or removing genes.

Answer 19

Genetic Engineering

Question 20

The genetic makeup of an individual that is represented by 2 letters

Answer 20

Genotype

Question 21

different versions of the same trait. We use letters to represent those traits. Everyone has two of these

Answer 21

alleles

Question 22

The trait that is overcome by a dominant trait. Can only show up if there are two of them.

Answer 22

Recessive trait

Question 23

Genes that have 2 different alleles. Hetero means different. (Rr)

Answer 23

Heterozygous
