Convergent vs Divergent Evolution - ANSWER -Divergent: one broad class but because of different features they diverge -Convergent: similar features between 2 different classes Punctuated Equilibrium vs Gradualism - ANSWER -Punctuated: concrete & defined phenotypes -Gradualism: phenotypes gradually evolve Speciation - ANSWER Formation of new species 1) Allopatric: separated by geographical barrier (mountain, ocean, river) -Barrier divides species 1 and species 2 2) Parapatric...

Reasons why Mendel used pea plants Correct Answer-Hermaphrodites (can self fertilize & cross easily) and discrete phenotypes Fundamental thing Mendel did Correct Answer-Count, allowing for systemization True Breeding Strain Correct Answer-produces own phenotype Mendel's Law of Segregation Correct Answer-1. One gene controls traits 2. 2 forms of a gene 3. Each individual has 2 alleles 4. Each parent contributes 1 allele 5. One allele is dominant to the other 6. Alleles separate equ...

Qualitative traits Ans: controlled by one or a few loci; discrete phenotypes (eye colour, coat colour, seed colour, seed texture, blood type, colourblindness etc) Quantitative traits Ans: controlled by multiple loci (also called polygenic traits); continuous phenotypes (height, weight, racing speed, milk yield, temperature, intelligence, temperament, schizophrenia - threshold trait) --> the range is measured as variation --> many loci contributing to the phenotype P = G + E An...
