$100 A: Being a scientist wasn’t Mendel’s main “job”. What job did Mendel have?
$100 Q: What is a monk?
$200 A: Mendel grew these plants, known in Latin as Pisum sativum.
$200 Q: What are pea plants?
$300 A: Mendel used “pure-breeding” plants for his P generation. These plants had genotypes in which the two alleles in a pair were the same. This term is now used to describe this genotype.
$300 Q: What is homozygous?
$400 A: Mendel found that when he crossed purple flowers x white flowers, all the offspring had purple flowers. The purple-flowered offspring were known as this generation.
$400 Q: What is the F1 generation?
$500 A: Mendel came up with these two laws of inheritance.
$500 Q: What are the Law of Segregation and Law of independent assortment?
$100 A: The study of the transmission of characteristics from parents to offspring.
$100 Q: What is genetics?
$200 A: A trait controlled by this allele masks the effects of other alleles for the same characteristic.
$200 Q: What is a “dominant” allele? http://www.supplementsuk.co.uk/gfx/cartoon_muscle.gif
$300 A: Mendel’s law stating that a pair of alleles is separated during the formation of gametes.
$300 Q: What is the “Law of Segregation?”
$400 A: When an offspring has two alleles in a pair that are different.
$400 Q: What is heterozygous?
$500 A: The term that describes the process in which a pair of homologous chromosomes does not properly separate; accounts for conditions such as Down’s syndrome. Image from http://www.i-claudius.com/cartoons/scrapbook02.html
$500 Q: What is nondisjuction?
$100 A: There are 23 pairs of these in the average human cell. Jeff Johnson www.stewartartists.com
$100 Q: What are chromosomes?
$200 A: Where genes are located; this marvelous, magical molecule is composed of sugars, phosphates, and nitrogen bases (A,T,G,C) www.alumni.ca/~laued3e/ conclusion.html
$200 Q: What is DNA (or deoxyribonucleic acid) ?
$300 A: The segments of DNA on a chromosome, called genes, code for the production of these molecules in a cell. www.mc.maricopa.edu/~tdclark/ biotechnology
$300 Q: What are proteins?
$400 A: Alternative forms of genes are called these.
$400 Q: What are alleles?
$500 A: The genes (alleles) someone inherits is described by this term.
$500 Q: What is genotype?
$100 A: Mendel transferred this from the anthers of flowers on one plant to the stigma of flowers on a different plant. http://www.sem.com/microsco/micrimag.htm
$100 Q: What is pollen? http://www.gbrownc.on.ca/~cnowak/1280.html
$200 A: Mendel crossed true-breeding purple flowered plants with true-breeding white flowered. All F1 generation offspring had this phenotype and genotype.
$200 Q: What is purple flowers and Pp? http://www.exn.ca/Stories/1999/10/21/55.asp
$300 A: If P=purple and p=white, 50% of Mendel’s F2 generation were of this genotype.
$300 Q: What is Pp? Pp
$400 A: If a parent has the genotype BbRr for brown hair (B) and rosy lips (R), these would be the possible ways in which alleles might be packaged into gametes.
$400 Q: What are BR, Br, bR, and br?
$500 A: The cross BbRr x BBrr results in this fraction of offspring with both brown hair (B) and rosy lips (R).
$500 Br Br Br Br Q: What is 1/2? BBRr BBRr BBRr BBRr BR Br BBrr BBrr BBrr BBrr bR BbRr BbRr BbRr BbRr br Bbrr Bbrr Bbrr Bbrr
$100 A: ABO blood types are an example of this exception to Mendel’s patterns of inheritance, in which both alleles may be dominant simultaneously.
$100 Q: What is codominance?
$200 A: The blood type of a person with the genotype ii. http://www.channelconsultants.net/mcinfo/tourism/wildlife/flora.htm
$200 A: What is type O?
$300 A: The blood type that results from a genotype of Iai.
$300 Q: What is type A?
$400 A: The blood type that results from a cross between parents with genotypes of IaIa and IbIb.
