Intro To Genetics

 Different forms of genes are called

• traits

• alleles

• monohybrid crosses

• gametes

The physical appearance of an organism is called its

• Assortment

• Genotype

• Phenotype

• Recessive

If two alleles are the same, they are said to be

• Dominant

• Homozygous

• Heterozygous

• Recessive

 If one form of a gene can overpower or mask another form, it is

• Dominant

• Recessive

• Homozygous

• Heterozygous

 Mendel’s law of segregation states that the two alleles for a given trait:

• Combine during meiosis (gamete formation)

• Separate at meiosis

•  Are eliminated during meiosi

•  Are tripled during meiosis

 A trait controlled by four alleles is said to have

• homologous alleles

• hybridization

• autosomes

• multiple alleles

 Eggs and sperm are both examples of  ____________.

• Alleles

• Gametes

• Offspring

• Monohybrid Cross

A monohybrid cross can be best described as 

• breeding among plants

• a cross among one pair of contrasting traits.

• a cross among two pairs of contrasting traits.

• a cross to test if an individual carries one or two dominant alleles.

The genetic makeup of an individual is its ___________________.

• Genotype

• Phenotype

• Dominance

• allelic frequency.

Alleles of different genes separate independently of one another during gamete formation is best described as:

•  Mendel’s law of independent assortment.

• Mendel’s law of allelic frequency.

• Mendel’s law of segregation.

• all of the above.
