Used when finding the possible genotypes for offspring when considering two traits at the same time

The form of a gene that is always expressed if present is the form

Two heterozygous purple-flowering pea plants are crossed. If purple is dominant over white, what are the expected  phenotypic results

What law BEST explains why an organism with ‘Tt’ will show only the dominant phenotype

If an organism inherits one dominant allele and one recessive allele for eye color, their genotype would be

Two parents have the genotype Gg for a genetic disorder caused by a recessive allele. What is the chance that any of  their children will inherit the disorder

Which Mendelian law of inheritance states that organisms inherit two copies of each gene and donate one copy to  each of their offspring

Two heterozygous parents. Each has a dominant allele (B) for brown eyes and a recessive allele (b) for blue eyes. What would the genotypic ratio of the offspring be

TT

If square is dominant over round, what is the phenotypes for the genotype: Ss

If square is dominant over round, what is the phenotypes for the genotype: ss

Some alleles are dominant others are recessive

Organisms inherit 2 copies of each gene, 1 from each parent, and only pass on 1 copy of each gene in their gametes

Genes for different traits assort independently during the formation of gametes

Having more than two alleles for one gene

A trait produced by two or more genes

Someone who carries the recessive trait, but doesn’t show it due to having a dominant X to mask it

For an XX female to express a recessive sex-linked trait, she must have

A cross between a purebred animal with red hairs and a purebred animal with white hairs produces all animals  with BOTH red and white hairs

In a cross between individuals of a species of tropical fish, all of the male offspring have long tail fins, and none  of the females possess the trait

A cross between a white horse and a chestnut (dark brown) horse produces all light brown horses

A cross between a tall sunflower and a short sunflower results in sunflowers with a range in heights

Any change in DNA

Mutations can be caused by all of the following except

In order for a mutation to be passed on from parent to offspring, the mutation must occur in

On a pedigree, how would a female individual with a disease be notated

If a mutation only changes the nucleotide sequence for a single protein, then it is known as

What kind of mutation occurred in the sex chromosome of an individual with the genotype XXY

Nondisjunction of autosomal chromosomes, such as chromosome number 21, can result in disorders like

Selective breeding produces
