Answer 18

Having two or more possible alleles at a locus

Question 19

Physical, observable expression of inherited traits; detectable products

Answer 19

phenotype

Question 20

Pedigree chart:

Answer 20

Visual map that displays a family history and can display inheritance patterns for individual traits

Question 21

Equal expression of both alleles in phenotype

Answer 21

Codominant

Answer 24

autosomal

Question 25

TRUE OR FALSE:
Traits are exhibited most commonly in males

Answer 25

TRUE

Question 26

Mendelian Inheritance Principles

Answer 26

Law of Independent Segregation
Law of Independent Assortment
Inheritance patterns: PUNNETT SQUARE

Question 27

This states that traits inherited from different chromosomes expressed separately and discretely.

Answer 27

Law of Independent Assortment

Question 28

These are useful for understanding inheritance of blood groups and ramifications of heterozygosity or homozygosity.

Answer 28

Punnett Squares

Question 29

Law of Independent Segregation

Answer 29

Two members of a single gene pair passed from one generation to the next in SEPARATE gametes

Question 30

TRUE OR FALSE
Agglutination reactions are generally weaker for homozygous cells and slightly stronger for heterozygous cells

Answer 30

FALSE
Agglutination reactions are generally STRONGER for homozygous cells and slightly WEAKER for heterozygous cells

Question 31

CIS is?

Answer 31

Genes inherited on the same chromosome

Question 32

Trans is?

Answer 32

genes inherited on SEPARATE chromosomes. This can weaken the trait’s expression.

Answer 33

Indirect: absent
