Genetics and Genetic Engineering
Who is the father of genetics? - correct answer-Gregor Mendel
What are alleles? - correct answer-One or more alternate versions of a gene or genes
How many alleles does an individual receive for one gene? - correct answer-2 alleles, 1 from
each parent
What is a genotype? - correct answer-An organisms genetic make-up
What is a homozygous genotype? - correct answer-When alleles are the same
What is a heterozygous genotype? - correct answer-When alleles are different
Which allele shows up if the genotype is heterozygous, Dominant or Recessive? - correct
answer-Dominant, since recessive stays 'covered up' by the dominant
What is an organism's phenotype? - correct answer-Their physical appearance
What are Mendel's 2 laws? - correct answer-1. Law of Segregation
2. Law of Independent Assortment
What is the law of segregation? - correct answer-alleles separate when gametes form
What is the law of independent assortment? - correct answer-alleles for each gene separate
independently of alleles for other genes
What is a punnett square? - correct answer-diagram to show all the possible genotypes of
the offspring based on the parents' phenotype
What are the 2 types of punnett square crosses? - correct answer-1. Monohybrid cross
2. Dihybrid cross
What is a monohybrid cross? - correct answer-determines the parents' genotypes and place
them on the outside of the Punnett Square...one allele over each square...fill in each square
with the alleles that belong in it and then determine genotype and phenotype ratio
What is a dihybrid cross? - correct answer-determine the genotypes for each gene for each
parent
What is incomplete dominance? - correct answer-heterozygous are a blend of the
parents...(ex. red x white = pink); Punnett squares are completed the same way you just
determine the heterozygous phenotype as a blend of both alleles
