Genetics Actual Questions and Correct Answers



Q1
Heredity
Answer: transmission of traits from one generation to the next




Q2
F1 Generation
Answer: hybrid offspring of the parental generation




Q3
F2 Generation
Answer: offspring of a cross between two F1 plants




Q4
Alleles
Answer: Variations of a gene. Everyone has two alleles for every gene.




Q5
Dominant allele
Answer: Allele that determines the organism's appearance. Usually denoted by a
capital letter (R)




Q6
Recessive allele
Answer: has no noticeable effect on an organism's appearance. Usually denoted by a
lowercase letter (r).




Q7
Wild Type
Answer: typical form of traits that are found most often in nature. Not always
dominant.

, Q8
Homozygous
Answer: Organism has the same alleles for a single gene (RR- homozygous dominant,
rr- homozygous recessive)




Q9
Heterozygous
Answer: Organism has different alleles for a single gene (Rr).




Q10
Homologous Chromosomes
Answer: genes will be at the same location (locus) on both.




Q11
Mendelian Genetics
Answer: Studied inheritance patterns in pea plants. He first recognized there are
certain traits and they pass to descendants.




Q12
Punnett squares
Answer: used to predict the genotypes and phenotypes of offspring




Q13
Law of segregation
Answer: During gamete formation, the alleles of each gene segregate from each other
so that each gamete carries only one allele for each gene.




Q14
Monohybrid Crosses
Answer: Cross between pure-bred parents for only one trait.
