Monohybrid Squares

What is the definition of the phenotype?

• The physical traits of an organism

• The genetic makeup of an organism

• The letters eg, Aa

• How the genotype is expressed.

Which answer includes the dominant homozygous genotype?

• AA

• Aa

• aa

Which answer contains the heterozygous genotype?

• AA

• aa

• Aa

What is the definition of an allele?

• An allele is a variety of a gene.

• An allele is the genetic makeup of an organism

• An allele is another word for a gene.

An allele whose trait only shows up when no dominant allele is present.

• hidden allele

• dominant allele

• recessive allele

• present allele

What is the definition of Homozygous?

• When one allele is dominant and one is recessive

• When an individual has two sets of the same allele.

• when it is neither dominant or recessive

A gene is...

• A heritable factor that controls a specific characteristic

• An allele

• A length of DNA which occupies a specific position on the chromosome

What does the law of segregation state?

• Separate genes are passed independently from each other, from parent to offspring.

• Every individual possesses two alleles for any particular trait and which allele a parent gives its offspring is completely random.

• Just because an allele is dominant, doesn't mean it is inherited more often.

• A recessive allele is expressed less than a dominant allele.

What does the law of independent assortment state?

• Punnet squares are able to predict the phenotypes and genotypes of offspring.

• Offspring inherit one allele from each parent.

• Separate genes are passed independently from each other from parent to offspring.

What is the law of dominance?

• One of the pairs of inherited traits will be dominant and the others recessive unless both the factors are recessive.

• There will always be a dominant allele.

• One of the pairs of inherited traits will be dominant and the others recessive.
