Clade A began diversifying 20 million years ago. There are 33 living species in Clade A and 6 species have gone extinct. Clade B began diversifying 10 million years ago. It has 14 living species and 5 species in Clade B have gone extinct. CALCULATE SPECIATION, EXTINCTION AND NET DIVERSIFICATION RATE (to the nearest 2 decimal places) TO DETERMINE WHETHER NET DIVERSIFICATION DIFFERS BETWEEN THE TWO CLADES.

6. in domesticated cats, the following are independently assorting: normal ears (t) is dominant to tufted ears (t); curved whiskers (c) is dominant to straight whiskers (c); the presence of six toes (s) is dominant to five toes (s); gene for hair length is an x-linked codominant. the three phenotypes for hair length are long (xhxh), medium (xhxh), and short (xhxh); medium is the heterozygous condition. given two parents: ttccssxhxh x ttccssxhy how many different gametes could be formed in the female cat with respect to these four traits? how many phenotypes are possible in the offspring from this mating?

Zoo geographic regions are characterized by the presence of specific groups of animals these regions are determined by the taxonomic or phylogenetic relationships of animals. the map shows the zoogeographic regions proposed by the naturalist alfred russel wallace in 1876. the similarities of organisms in which two areas numbered above provide the best evidence for common ancestry between the organisms in both locations ?

The illustration shown is an ovum, a female sex cell. a mutation in this cell may be passed to the woman’s offspring during a) birth. b) mitosis. c) dna replication. d) sexual reproduction
