B) increase the number of heterozygotes in the population. C) reduce the number of individuals with diseases in the population. D) increase the fertility of individuals in the population Individual beak size of individual finches of the Galápagos Islands A) may change during a bird's lifetime. B) will always match the beak size useful for seed foraging. C) has nothing to do with overall population characteristics. D) will greatly influence individual survival. According to the Hardy-Weinberg principle, the following must be true for gene frequencies in a population to remain the same. A) Mating is random. C) The population is small. B) Mutations occur consistently D) Natural selection occurs. What is the primary original source of genetic variation in a population? B) genetic drift C) blending inheritance A) mutation D) cloning The tongue length of an animal is controlled by two alternative alleles at a single locus, L (long) and I (short). If an individual has parents that are both homozygous dominant, the individual will be A) homozygous dominant with a long tongue. B) heterozygous with a long tongue. C) heterozygous with a short tongue. D) homozygous recessive with a long tongue. The fitness of an individual is measured by A) the proportion of heterozygous alleles within its genome. B) its body size. C) its efficiency in obtaining energy D) the proportionate contribution the individual makes to future generations through its offspring.

Explanation / Answer

Answer:

What is the correct order of the steps regarding speciation?

Option c

one species geographic isolation reproductive isolation two species

The effect of positive assortative mating is to

Option A

increase the number of homozygous in the population

Individual beak size of individual finches of the Galapagos Islands

Option D

Will greatly influence individual survival

according to the hardy-weinberg principle, the following must be true for gene frequencies in a population to remain the same:

Option A

Mating is random

What is the primary original source of genetic variation in a population?

Option A

Mutation

The tongue length of an animal is controlled by two alternative alleles at a single locus, L (long) and l (short). If an individual has parents that are both homozygous dominant, it will be

Option A

homozygous dominant with a long tongue.

The fitness of an individual is measured by

Option D

the proportionate contribution the individual makes to future generations through its offspring
