_____ Alternative forms of a trait are encoded by alternative alleles. _____ The 2 alleles for a given trait separate when gametes form. _____ Each allele has an equal probability of being passed on to the gametes. _____ Allele pairs segregate independently of each other. _____ Diploid individuals have 2 alleles for each trait.
When several possible phylogenetic trees can be produced from a data set, the most parsimonious tree:
A. is the one that shows the smallest number of evolutionary changes. B. is the one that shows the largest number of nodes. C. is the one that shows the largest number of analogous characteristics. D. is the one that shows the smallest number of synapomorphies. E. is the one that shows the smallest number of branches.
In corn, having ligules (L) is dominant to liguleless (l), and green leaves (G) is dominant to white leaves (g). If a pure-breeding plant that is liguleless and has green leaves is crossed to a pure-breeding plant with white leaves and ligules, predict the genotypes and phenotypes of the F1.
A) LL GG, green and ligules B) Ll GG, green and ligules C) Ll Gg, green and ligules D) ll gg, white and liguleless E) Ll gg, green and liguleless
