Mendelian and Non-Mendelian Genetics

Front

What is the phenotype?

Back

The phenotype is the physical appearance of an organism.

What is the probability of getting white fur if B = brown fur and b = white fur in a Punnett square?

Back

The probability for white fur is 50%.

Front

If a person has the genotype BB, what color hair do they have if B = Blonde Hair and b = Brown Hair?

Back

They would have Blonde Hair.

Front

What is the genotype for a yellow plant if G = green and g = yellow?

Back

The genotype for a yellow plant is gg.

Front

How many alleles does a child inherit from each parent for each trait?

Back

A child gets 1 allele from each parent for each trait.

Front

What is an allele?

Back

An allele is a variant form of a gene that determines a specific trait.

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

What is a Punnett square used for?

Back

A Punnett square is used to predict the genetic outcomes of a cross between two organisms.

Front

What is the difference between dominant and recessive alleles?

Back

A dominant allele masks the effect of a recessive allele in a heterozygous genotype.
