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

• homozygous

• heterozygous

• dominant

• 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 meiosis

• are tripled during meiosis

A trait controlled by four alleles is said to have

• homologous alleles

• autosomes

• hybridization

• multiple alleles

Eggs and sperm are both examples of ____________.

• alleles

• gametes

• monohybrid crosses

• offspring

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.

• dominance.

• phenotype.

• allelic frequency.

NGSS.HS-LS1-1

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.
