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
