AP Bio & Genetics Review: Heredity

Front

What is the result of mitosis in terms of chromosome number in fruit flies?

Back

After mitosis, a fruit fly daughter cell will have 8 chromosomes.

Front

What is the reason for variability in height among children of a very tall and a very short person?

Back

Human height is controlled by multiple genes.

Front

What is the term for the observable outward manifestation of an individual's genes?

Back

Phenotype.

Front

What is the sequence of genes on a chromosome if the crossover frequencies are determined to be vg - pr - eb?

Back

The sequence of genes is vg - pr - eb.

Front

What conclusion can be drawn about height increase across generations in a study?

Back

There was not a significant increase in the F1 generation but there was after two generations compared to the P1.

Front

Define genotype.

Back

Genotype refers to the genetic makeup of an individual, including all alleles.

Front

What is incomplete dominance?

Back

Incomplete dominance is a genetic situation in which one allele does not completely dominate another allele, resulting in a phenotype that is a blend of the two.

Front

What is co-dominance?

Back

Co-dominance occurs when both alleles in a heterozygote are fully expressed, resulting in a phenotype that shows both traits.

Front

Explain the concept of multiple alleles.

Back

Multiple alleles refer to the presence of more than two alleles for a genetic trait within a population.

Front

What is a genetic map?

Back

A genetic map is a representation of the arrangement of genes on a chromosome.
