All 16 questions and answers
Genes located on the same chromosome that do not assort independently?
Answer: Linked Genes
Any chromosome that is not a sex chromosome?
Answer: Autosome
The failure of homologous chromosomes or sister chromatids to separate during meiosis?
Answer: Nondisjunction
An individual with a different combination of alleles than either of its parents (due to crossing over or independent assortment)?
Answer: Recombinant
Unit of distance between genes on a chromosome, where 1 unit = 1% recombination frequency?
Answer: Map unit (centimorgan)
A statistical test used to determine if there is a significant difference between observed and expected genetic ratios?
Answer: Chi-squared test
Traits controlled by two or more genes, showing continuous variation (e.g., skin color)?
Answer: Polygenic inheritance
Interaction in which one gene masks the effect of another gene at a different locus?
Answer: Epistasis
The combination of alleles inherited by an organism (e.g., Tt)?
Answer: Genotype
The observable physical characteristics of an organism, determined by genotype and environment?
Answer: Phenotype
Having two identical alleles for a specific gene?
Answer: Homozygous
Having two different alleles for a specific gene?
Answer: Heterozygous
An allele that has the same effect on the phenotype whether it is present in the homozygous or heterozygous state?
Answer: Dominant
An allele that only has an effect on the phenotype when present in the homozygous state?
Answer: Recessive
Alleles that are both fully and separately expressed in a heterozygote (e.g., AB blood type)?
Answer: Codominant
Cases where the heterozygote has an intermediate phenotype (e.g., red and white flowers making pink)?
Answer: Incomplete Dominance
Play it as a class game
Play this set opens it in splycr, where you can host it for your class straight away. Hosting needs no account: put the room code on the projector, and students join from a phone with the code and their first name. Each question plays as multiple choice, and the three wrong options are other answers from the same set.
