Q

What is dna?

A

Chromosomes found in the nucleus

17
Q

what is gene

A

Part of DNA found on a chromosomes that contains information for a specific inherited trait

18
Q

what is allele?

A

one pair of genes that determines a specific genetic trait

19
Q

what is a phenotype

A

The physical properties o an organism (high, hair color, etc)

20
Q

what is a genotype

A

a written code that expresses the inherited combination of alleles in an organism (CC,Cc,cc)

21
Q

What is Heredity

A

Passing traits from parent to offspring

22
Q

Dominant Trait

A

the characteristics visible when at least one dominant allele for a trait is inherited

23
Q

Recessive Trait

A

characteristic that is visible only when two recessive alleles for a particular trait

24
Q

Homozygous

A

Organism that carries two dominant or two recessive alleles for a particular trait

25
Q

Heterozygous

A

Organism that carries both dominant and a recessive allele for a particular trait

26
Q

What is Cloning

A

Technique scientist use to make exact genetic copies of living things

27
Q

Pros of cloning

A

No need classical reproduction
works without partners
not vulnerable to sexually transmitted diseases
progress has been made over the past decade
more socially accepted
efficient process
help the human species survive
help prevent the extinction of species
we can preserve genetic material
help increase food production
genetic research becomes more efficient with cloning
help for organ replacements
help to remove defective genes

28
Q

Cons of cloning

A

Humans should not play god
not in line with traditional values
may not be in line with many religions
considered unethical
not mature yet
may pose serious long-term risk
may become more vulnerable to diseases
not entirely safe
very expensive
unknown consequences for life on earth may be used for the bad
may be used in military operations
lack of genetic uniqueness may become a problem

29
Q

what is In vitro fertilization (IVF)

A

One of several techniques available to help people with fertility problems have a baby.

30
Q

What are the steps of IVF?

A

Ovarian stimulation hormone therapy
egg pick up
sperm preparation
egg fertilization
embryo development
embryo transfer
