Which of the following is a condition that must be met for a population or an allele to be in Hardy-Weinberg equilibrium?A The population in question must be small
B Organisms must be free to migrate into or out of the population
C New mutations must be introduced to the gene pool at a consistent and unfluctuating rate
D Organisms in the population must express no mating preferences

Answers

Answer 1

Answer: The answer is D) Organisms in the population must express no mating preferences.

Some of the conditions that must be met for a population or an allele to be in Hardy-Weinberg equilibrium are:

1. The population must be very large - so A) could not be the right answer.
2. There must be no migration and population must be isolated - so B) could not be the right answer.
3. There must be no mutations - so C) could not be the right answer.
4. There must be random mating, which means there are no mating preferences - so, D) is the right answer.

A gardener crosses tall true–breeding pea plants with short true–breeding ones. Tall plants are dominant to short ones. He collects the seeds to grow F1 plants and then allows them to self–pollinate to form an F2 generation. Which of the following describes the traits of the offspring correctly?

Answers

If the parental plants (P-generation) have the genotypes TT (tall) and tt (short), respectively, all the F1 plants will be tall heterozygotes (genotype Tt).

>Those Tt-plants will (statistically) have the following distribution of genotypes and phenotypes among their offspring (the F2 generation): 25% TT (tall homozygotes); 50% Tt (tall heterozygotes) and 25% tt (short homozygotes).

>In other words: 3/4 of the offspring will have the tall phenotype (genotypes TT and Tt); and 1/4 will be short plants (genotype tt). -

A chimpanzee using a long twig to catch termites is an example of a(n) _____.a. external stimulus
b. patterned behavior
c. learned behavior
d. innate behavior

Answers

The correct answer is C. Learned behavior.

A chimpanzee uses the long twig to catch termites is an example of learned behavior. Chimpanzee belongs to the taxonomic genus called pan. It has two extant species, for example, bonobo and common chimpanzee.

They belong to the family Hominidae together with orangutans, gorillas, and humans. They are found in the Congo jungle.

A chimpanzee using a long twig to catch termites is an example of a learned behavior - c.

When a chimpanzee first observed that using a twig to catch termites could be a useful way of dealing with the termites, he noted that he could do it from then on.

5. How does water reach the leaves from the root? A) Stomata B) Xylem C) Phloem D) All of the above

Answers

Answer:

B.Xylem

Explanation:
