Unit 4 Genetics Review

Front

What are the monomers that form a strand of DNA?

Back

Nucleotides are the monomers that are repeatedly joined together to form a strand of DNA.

Front

How many chromosomes do fruit fly daughter cells have after mitosis if they originally have 8 chromosomes?

Back

Fruit fly daughter cells have 8 chromosomes after mitosis.

Front

What are the possible genotypes and phenotypes of offspring from crossing two pink (RW) flowers?

Back

The offspring will have 50% pink (RW), 25% white (WW), and 25% red (RR).

Front

What DNA base sequence pairs with the strand ATG TGA CAG?

Back

The sequence that pairs with ATG TGA CAG is TAC ACT GTC.

Front

What does heterozygous mean in genetics?

Back

Heterozygous means that the alleles are different.

Front

What is the function of DNA?

Back

DNA stores genetic information and provides instructions for the development and functioning of living organisms.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Front

Define genotype.

Back

Genotype refers to the genetic makeup of an organism, specifically the alleles it possesses.

Front

Define phenotype.

Back

Phenotype refers to the observable characteristics or traits of an organism, influenced by its genotype and environment.

Front

What is a dominant allele?

Back

A dominant allele is an allele that expresses its trait even when only one copy is present in the genotype.
