Mendel Genetics Review

Front

What is the expected phenotypic ratio of offspring from a monohybrid cross?

Back

3:1 ratio of dominant to recessive traits.

Front

Define genotype.

Back

The genetic makeup of an organism, represented by alleles.

Front

What is a Punnett square used for?

Back

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

Front

What does incomplete dominance mean?

Back

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

Front

What is the difference between phenotype and genotype?

Back

Phenotype is the physical expression of a trait, while genotype is the genetic makeup.

Front

What is a homozygous genotype?

Back

A genotype consisting of two identical alleles for a trait.

Front

What is a heterozygous genotype?

Back

A genotype consisting of two different alleles for a trait.

Front

What is the significance of the F1 generation in genetics?

Back

The first generation of offspring from a cross of two parental organisms.

Front

What does the term 'allele' refer to?

Back

Different forms of a gene that can exist at a specific locus.

Front

What is the expected phenotype of a heterozygous individual for a trait with complete dominance?

Back

The phenotype will express the dominant trait.
