Sticky Ball
Who is known as the Father of Genetics?
Gregor Mendel
In Pea plants, Tall (T) is dominant to short(t); if you crossed a
heterozygous tall pea plant with a short pea plant what would be the probability of tall plants and short
plants.?
Tall 50%Short 50 %
If you have the same two alleles for a trait, you are __________ or ______________ for that trait
Homozygous or purebred
For Purple People Eaters having a long tail(L) is incompletely dominant to having (N)no tail, what type of tail
would a PPE have if its genotype was LN
Medium or short tail
What are the chances the offspring of a short tailed PPE and a long tailed PPE
will have long tails? Short tails? No Tails?
Long tails 50%Short 50%No tail 0%
In PPE’s Red noses and White Noses are co-dominant over green noses, show a
Punnett square for a pink nosed PPE mating with a heterozygous white nosed PPE and give the probabilities for each
possible phenotype
Pink 25%, White 50%, Red 25%
For ABO Blood type the A and B alleles are co-dominant to the O
allele, if a man is homozygous Type A and the woman is heterozygous Type B, what are the probabilities
of their children’s blood type?
Type AB 50%, Type A 50%
For ABO Blood type the A and B alleles are co-dominant to the O
allele, if a couple’s blood types are heterozygous Type A and Type O; what are the probabilities of their
children’s blood types
Type A 50%, Type O 50%
Beginning with cytokinesis list the phases of the cell cycle in the
correct orderCytokinesisInterphaseProphaseMetaphaseAnaphaseTelophaseCytokinesis
Cell that contains both copies of the chromosome pair (2n)
Diploid
Cell division for the growth or repair of the organism
Mitosis
Who discovered the shape of the DNA molecule?
Watson and Crick
The sides of the DNA molecule are made up of alternating
_________and ______________ molecules.
Sugar (deoxyribose) and phosphate
The rungs or steps of the DNA molecule are ___________
Nitrogen Bases
The nitrogen bases are held together by ____________
Hydrogen (H) bonds
The shape of the DNA molecule is called __________________ and
can be described as a ______________
Double HelixTwisted ladder or spiral staircase
What does DNA stand for?
Deoxyribonucleic acid
Process in which DNA copies itself?
DNA replication
Cell division that begins with DNA replication
Your toss will be multiplied for each correct answer you write
Mitosis, Meiosis and Binary Fission
Process in which DNA transfers its code to RNA
Transcription
Make a chart showing three structural differences between DNA and RNA
DNA has a different sugarRNA uses Uracil instead of ThymineRNA is single stranded, DNA is double stranded
Passing of traits from parents to offspring
Heredity
Cell Division that produces genetically identical cells
Mitosis
Cell division that only occurs in germ cells
Meiosis
Cell division that produces gametes (sperm or egg cells)
Meiosis
Cell division that involves crossing over, the exchanging of genes on homologous chromosomes; helps to ensure genetic
diversity and uniqueness
Meiosis
Cell Division that produces haploid cells
Meiosis
If a leaf cell contains 28 chromosomes, how many
chromosomes would you expect to find in its pollen grain
Pollen grains are sex cells, which are haploid so 14
If this were one side of DNA, what would the transcribed molecule be
A-T-A-G-C-C-
U-A-U-C-G-G
If this were one side of DNA, what would the complimentary side be
A-T-A-G-C-C
T-A-T-C-G-G
Process the ribosome carries out to assemble protein molecules
TranslationReading of the mRNA strand and linking of
amino acids brought by tRNA to form the protein molecule
A dog’s egg cell contains 32 chromosomes, how many would
you find in its skin cell?
64Egg cells are haploid, skin cells are diploid
Which cell organelle is the site of cellular respiration?
Mitochondria
Which cell organelle captures light energy to make sugar for the cell?
Chloroplast
Which cell organelle acts as a storage area holding food, water or
waste for the cell?
Vacuole
