Across
1.evolutionary theory tenet saying species evolve slowly and continuously over long periods
4.maintains an intermediate expression of a trait by selection against extreme variants
5.substance consisting of a double helix which holds genetic material
6.threadlike bodies consisting of chromatin that carry the genes in a linear order
7.rudimentary structure corresponding to a functional structure in ancestral animals
8.changes in population in which extreme values for a trait are favored over intermediate ones
10.when natural selection favors a single phenotype so allele frequency shifts in one direction
11.hypothesis saying species evolution follows pattern of stability for long periods with shorter ones
Down
1.random changes in the frequency of alleles in a gene pool
2.nonhereditary change made in response to the environment.
3.alteration of allele frequencies of particular genes in a population
9.gene forms usually arising through mutation responsible for hereditary variation
