Basic Genetics

How many allele combinations would be found in the gametes produced if the genotype is TtYy? Use FOIL.

• a. 2
• b. 4
• c. 8
• d. 12

What is formed at the end of meiosis?

• a. two genetically identical cells
• b. two genetically different cells
• c. four genetically identical cells
• d. four genetically different cells

Gametes have 

• a. two sets of chromosomes
• b. homologous chromosomes
• c. one allele for each gene
• d. two sets of chromosomes

If an organisms diploidnumber is 10, its haploid number is:

• a. 2
• b. 5
• c. 10
• d. 20

If you flip a coin 10 times, using the punnett square what is the  probability of getting two heads or two tails is

• a. 1
• b. 1/2
• c. 1/4
• d. 3/4

It is in a form of a gene:

• a. chromosome
• b. allele
• c. phenotype

It is the genetic make-up of an organism:

• a. allele
• b. phenotype
• c. genotype

There are two different alleles in a particular gene:

• a. homologous
• b. heterozygous
• c. homozygous

There are two identical alleles for a particular gene;

• a. homozygous
• b. homologous
• c. heterozygous

The principles of probability can be used to:

• a. predict the traits of the offspring of a genetic cross
• b. determine the actual outcome of genetic cross
