Give 3 examples of characteristics you might find on a dichotomous key. Complete the attached Dichotomous Key for added practice. True/False - Mark your answer. Correct any false statements to make them true. 1 A recessive trait is ÿveÿsÿeÿ. Genes control traits. o 3. ÿuÿeproduction only involves one parent. Chromosomes are found in the nucleus of a cell. Asexual offspring are genetically identical to their parent.`' o The presence of a rightly colored detachale tail is an advantage for some lizards ecause predators are more likely to gra them y the tail.. A dichotomous key is used to identify different types of organisms. Budding is a type ofÿrÿfreproduction. Camouflage is an adaptation that increases survival. All humans haveÿ4ÿ5ÿchromosomes
