Genetics was a monk who studied the genetics of pea plants. Describe the P, F1, and F2 generations and how they arise. True breeding organisms produce offspring of the same variety. True/False A unit of heritable information that is a specific nucleotide sequence is called a what? Alternative versions of this unit at the same locus are called what? Describe the difference between dominant and recessive alleles. Homozygous and Heterozygous individuals. The genotype is the observable version of a gene. True/False The states that the 2 alleles for a heritable character separate in gamete formation in to different gametes. Using a Punnett square cross Pp x Pp and TTRr x ttRR, and give the expected genotypic and phenotypic ratios. Which one is a monohybrid cross and which one is a dihybrid cross? A can be used to determine an organism’s genotype by crossing it with a Homozygote. What is independent assortment? Incomplete dominance results in heterozygotes being intermediates of both homozygotes. T/F results in both phenotypes being expressed by the heterozygote. Describe the difference between multiple alleles, pleiotropy, and polygenic inheritance. What is epistasis? A heterozygote that can transmit a recessive disorder is called a . Cystic fibrosis and sickle-cell disease are dominantly inherited characters. True/False A trait that is the result of a gene on a sex chromosome is called a . Describe the chromosome theory of inheritance. increases genetic diversity in meiosis I by exchanging genetic information between chromosomes. Linked genes are on different chromosomes. True/False A error in meiosis or mitosis that causes chromosomes to move apart improperly is called . Describe the difference between aneuploidy and polyploidy.
