Explain how Mendel cross pollinated his pea plants - Hand pollinated Explain the difference between dominant & recessive alleles - Dominant is stronger and will show up with a better chance than recessive Give 4 reason that Mendel used garden peas for his experiments - Small area, lots of offspring, self pollinate, and artificially cross pollinated Heterozygous genotypes are also called - Hybrid How did mendel get pure plants - He allowed the plants to self-pollinate for several generations How did Mendel's experimental results compare to the theoretical genotypic ratios? - 3-1 compare to 2.96-1 How is Mendel referred to today - Father of Genetics In what country did Mendel do his research on peas? - Czech Republic Mendel stated that physical traits were inherited as - Particles Name & describe two types of genetic crosses - Monohybrid cross - Single trait Dihybrid cross = Involving 2 traits Name the male and female parts of a flowering plant and explain how pollination occurs - Male = pollen Female = OvaryToday we know that particles are actually what - Chromosomes and DNA Using a letter of the alphabet, show how each allele would be represented - Rr What are alleles & what are the two forms? - Two forms of a gene - Dominant & Recessive What are homozygous genotypes - Gene combination involving 2 dominant or 2 recessive genes What did Mendel notice about offspring traits? - Retained traits of the parents What does P1 mean - Parental Generation What is a genotype and write 3 possible genotypes? - Gene combination for a trait RR, Rr, rr What is a phenotype and write possible phenotypes for your genotypes in question 18? - Phenotype - the physical feature resulting from a genotype What is meant by a heterozygous genotype - Gene combination of one dominant & one recessive allele What is the difference between self and cross pollination? - Self - occurs in the same plant Cross - Occurs between plants What is the F1 Generation? - First generation offspring
