Genetics and Genetic Engineering

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? - COR
