Genetics Unit 5 Review

Front

What does the law of independent assortment state?

Back

The law of independent assortment states that the selection of one allele for a trait does not influence the selection of another allele for a different trait.

Front

If a flower is white and purple is dominant, what is its genotype?

Back

The flower must be homozygous for white (ww).

Front

In a pedigree, shaded symbols represent individuals with which type of trait?

Back

Shaded symbols represent individuals that express the dominant trait.

Front

What is the probability of offspring having blue eyes if one parent is BB and the other is hh?

Back

0% probability of having blue eyes.

Front

What is co-dominance in genetics?

Back

Co-dominance is a form of inheritance where both alleles in a heterozygote are fully expressed, resulting in a phenotype that is neither dominant nor recessive.

Front

What is the genotype of an individual with a widow's peak if they are heterozygous?

Back

The genotype would be Aa.

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene.

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene.

Front

In a genetic cross, what does a Punnett square illustrate?

Back

A Punnett square illustrates the possible genotypes of offspring from a genetic cross.

Front

What is the expected phenotype ratio in a monohybrid cross?

Back

The expected phenotype ratio in a monohybrid cross is typically 3:1 for dominant to recessive traits.
