Mendelian and Non-Mendelian Genetics

Front

What is the genotype?

Back

The genetic makeup of an organism.

Front

What does a gene contain instructions for assembling?

Back

Proteins.

Front

In a Punnett square, if T = tall and t = short, what is the genotype of a homozygous recessive individual?

Back

tt.

Front

If B = brown fur and b = white fur, what is the probability of getting white fur from a cross of Bb x Bb?

Back

50%.

Front

If B = blonde hair and b = brown hair, what would be the phenotype of a person with the genotype BB?

Back

Blonde hair.

Front

What is the difference between phenotype and genotype?

Back

Phenotype is the physical appearance, while genotype is the genetic makeup.

Front

What is a Punnett square used for?

Back

To predict the genotypes and phenotypes of offspring from genetic crosses.

Front

What is the principle of segregation in genetics?

Back

During the formation of gametes, the two alleles for a trait separate from each other.

Front

What is the principle of independent assortment?

Back

Genes for different traits can segregate independently during the formation of gametes.

Front

What is incomplete dominance?

Back

A genetic situation where one allele does not completely dominate another, resulting in a new phenotype.
