Forensics

Question 1

homogygous

Answer 1

the same alleles
Ex: TT or tt

Blood type: IA IA or ii or IB IB

Question 2

heterogzygous

Answer 2

different alleles
Ex: Tt
Blood types
- A and B can be heterogygous

Question 3

dominant

Answer 3

• capital allele
• we will “see” the trait if there is only one or both allele(s) present

Question 4

recessive

Answer 4

• lower case allele
• only “see” the trait if both alleles are recessive
  Ex: tt

Question 5

antigens

Answer 5

proteins in the blood cells

Question 6

antibodies

Answer 6

immune system attacking the UNKNOWN antigens

Question 7

blood types

Answer 7

A+, A-, B+, B-, AB+, AB-, O+, O-

Question 8

Rh antigens

Answer 8

Rh+ and Rh-

Question 9

DNA structure

Answer 9

• Made out of nucleotides put together
• sugar, phosphate for backbone
• double helix
• rungs - 4 types

Question 10

3 parts of the nucleotides

Answer 10

• made out of sugars, phosphates, and base

Question 11

4 possible DNA bases

Answer 11

• Adenine
• Thymine
• Cytosine
• Guanine

Question 12

phenotype

Answer 12

physical characteristics
Ex: tall/short
Ex: A

Question 13

genotype

Answer 13

genes
Ex: Tt and TT
Ex: IAIA or IAi

Question 14

Mendel’s Laws

Answer 14

• Segregation
• Independent Assort
• Dominance

Question 15

Incomplete Dominance

Answer 15

• neither allele is completely dominant over the other
  - mix
  Ex: (Red + White = PINK)
  (RR + WW = RW)

Question 16

Codominance

Answer 16

• both alleles are present equally
  - spotted
  Ex: (Red + White = Red/White)
  (RR + WW = RW)
