____________________ IS THE
“FATHER OF GENETICS”.
_______________ IS THE PASSING OF
TRAITS FROM PARENT TO OFFSPRING.
A _________ REPRESENTS THE
PHYSICAL CHARACTERISTICS.
HOW MANY CHROMOSOMES WOULD A
HUMAN HAVE IN THEIR SKIN CELLS?
___________ ARE TWO FORMS OF A
GENE (DOMINANT & RECESSIVE)
HOW WOULD YOU WRITE A HOMOZYGOUS
DOMINANT GENOTYPE (USE THE 2ND
LETTER OF THE ALPHABET )
A HOMOZYGOUS GENOTYPE CAN ALSO
BE CALLED _____________
WHICH LAW STATES: WHEN DIFFERENT
ALLELES FOR A CHARACTERISTIC ARE
INHERITED (HETEROZYGOUS), THE TRAIT
OF ONLY ONE (THE DOMINANT ONE)
WILL BE EXPRESSED?
WHAT SEX CHROMOSOMES ARE
PRESENT FOR A MALE?
WHAT DOES THE P GENERATION
REPRESENT?
A CROSS BETWEEN TWO HYBRIDS WILL
ALWAYS CREATE WHAT PHENOTYPIC
RATIO?
BE SPECIFIC!!!!
WHAT ORGANISM DID MENDEL USE
TO CONDUCT HIS RESEARCH?
WHAT IS THE F1 GENERATION?
____________ IS THE STUDY OF
HEREDITY
WHICH LAW STATES THE FOLLOWING:
EACH FACTOR (GENE) IS DISTRIBUTED
(ASSORTED) RANDOMLY AND
INDEPENDENTLY OF ONE ANOTHER IN
THE FORMATION OF GAMETES (EGG OR
SPERM)?
A ___________ REPRESENTS THE
TYPES OF GENES THAT ARE INHERITED.
HOW MANY CHROMOSOMES DID YOU
INHERIT FROM YOUR MOM?
HOW WOULD YOU WRITE A HOMOZYGOUS
RECESSIVE GENOTYPE (USE THE 2ND
LETTER OF THE ALPHABET )
A HETEROZYGOUS GENOTYPE CAN
ALSO BE CALLED A _____________
HOW WOULD YOU WRITE A
HETEROZYGOUS GENOTYPE (USE THE
2ND LETTER OF THE ALPHABET )
WHICH LAW STATES: EACH GENETIC TRAIT
IS PRODUCED BY A PAIR OF ALLELES
WHICH SEPARATE DURING
REPRODUCTION?
LIST THE GAMETES THAT CAN BE
PRODUCED FROM THE FOLLOWING
GENOTYPE:
A ______ GENE IS THE GENE THAT SHOWS
UP MOST OFTEN IN A CROSS; REPRESENTED
BY AN UPPERCASE LETTER
IN GUINEA PIGS, ROUGH COATS (R) ARE
DOMINANT TO SMOOTH COATS. WRITE
THE GENOTYPE FOR A HOMOZYGOUS
ROUGH COATED GUINEA PIG.
IN GUINEA PIGS, ROUGH COATS (R) ARE
DOMINANT TO SMOOTH COATS. WHAT
ARE THE F1 GENOTYPES FROM A CROSS
WITH A SMOOTH COATED GUINEA PIG
AND A HOMOZYGOUS ROUGH COATED.
ARE FRATERNAL TWINS OR IDENTICAL
TWINS MORE CLOSELY RELATED?
IN GUINEA PIGS, ROUGH COATS (R) ARE
DOMINANT TO SMOOTH COATS. WRITE
THE GENOTYPE FOR A SMOOTH COATED
GUINEA PIG.
A ________ IS A CROSS THAT ONLY
INVOLVES A SINGLE TRAIT
LIST THE GAMETES THAT CAN BE
PRODUCED FROM THE FOLLOWING
GENOTYPE:
WHAT ARE TWO FACTORS THAT
AFFECT WHO YOU ARE?
WHAT SEX CHROMOSOMES ARE
PRESENT FOR A FEMALE?
HOW COULD A GUINEA PIG BREEDER
DETERMINE IF A BLACK GUINEA PIG IS
HOMOZYGOUS DOMINANT OR
HETEROZYGOUS?
________ IS A TOOL USED TO SOLVE
GENETIC PROBLEMS BASED ON
PROBABILITY
IN GUINEA PIGS, ROUGH COATS (R) ARE
DOMINANT TO SMOOTH COATS. WHAT
ARE THE F1 PHENOTYPES FROM A CROSS
WITH A SMOOTH COATED GUINEA PIG
AND A HOMOZYGOUS ROUGH COATED.
A ________ IS A CROSS THAT
INVOLVES TWO TRAITS
A ______ GENE IS THE GENE THAT SHOWS
UP LESS OFTEN IN A CROSS; REPRESENTED
BY A LOWERCASE LETTER
IN GUINEA PIGS, ROUGH COATS (R) ARE
DOMINANT TO SMOOTH COATS. WRITE
THE GENOTYPE FOR A HETEROZYGOUS
ROUGH COATED GUINEA PIG.
THE ________________________ IS
BASED ON THE GENOTYPE.
WHICH PARENT DETERMINES THE SEX
OF THE CHILD? WHY?
T OR F: THE TENDENCY TO PRODUCE
TWINS RUNS IN A FAMILY.
HOW DO IDENTICAL TWINS FORM?
IN CORN, SMOOTH SEED TEXTURE (T) IS DOMINANT
TO WRINKLED SEED TEXTURE. COMPLETE A TEST
CROSS OF A HYBRID SMOOTH SEED TEXTURE CORN.
DETERMINE THE GENOTYPES & PHENOTYPES OF
THE OFFSPRING.

PHENOTYPES OF A CROSS BETWEEN A
HOMOZYGOUS BROWN EYED INDIVIDUAL AND
SOMEONE WITH BLUE EYES.

2. IN GUINEA PIGS ROUGH COATED (R) IS DOMINANT
OVER SMOOTH COATED (R) AND BLACK COLOR (B) IS
DOMINANT OVER WHITE COLOR (B). A ROUGH COATED
AND BLACK GUINEA PIG, WHOSE MOTHER WAS SMOOTH
AND WHITE IS MATED WITH A SMOOTH, WHITE ANIMAL.
WHAT ARE THE PARENT GENOTYPES? WHAT ARE THE
GENOTYPES AND PHENOTYPES OF THE OFFSPRING? (SEE

3. IN SQUASH THE COLOR WHITE (W) IS DOMINANT OVER
YELLOW AND DISK SHAPE (D) IS DOMINANT OVER SPHERE
SHAPE. A) WHEN CROSSING TWO HOMOZYGOUS
SQUASHES, ONE WHITE, SPHERE AND THE OTHER YELLOW,
DISK.
DETERMINE THE PARENT GENOTYPES. THEN
DETERMINE THE GENOTYPES AND PHENOTYPES OF THE F1
