In Drosophila, the genes r and s are linked. Flies of genotype r s/r s and rs /rs are crossed and an F1 obtained. The F1 allele arrangement is called:

Answers

Answer 1

Answer:

repulsion (trans)

Explanation:

Repulsion refers to the phenomenon by which each homologous chromosome contains one dominant and one recessive allele from two different linked genes. A trans arrangement occurs when an individual is heterozygous for two linked genes, where the recessive allele for one particular gene is located on the same chromosome as the dominant allele for the other linked gene, thereby dominant and recessive alleles are said to be “in repulsion”. Conversely, a cis arrangement occurs when both dominant alleles are located on one chromosome and both recessive alleles on the other.

Fire and Mello conducted an experiment where they added no gene X RNA (b), anti-sense gene X RNA (c) or double stranded gene X RNA (d) to C. elegans embryos. They then did a hybridization experiment examining gene X mRNA levels in the embryo. Square (a) is a no probe control. How does this act as a control

Answers

Answer:

The correct answer is - It shows that an RNA probe is necessary to get a signal.

Explanation:

A probe is a specific single-stranded sequence of DNA or RNA that recognizes its complementary sequence in a particular sample genome for synthesis. The RNA probe is placed into close contact with the given sample under a specific environment that allows the RNA probe sequence to hybridize with its complementary sequence.

In this case, square a is the condition where no RNA probe is persent whereas all three other conditions have some sort of RNA probe, however, in C there is no Gene X probe but their probe present. To get a signal in hybridization RNA probe is required and that can be used as control as it can be used to compare if a signal is received or not.

Answers

Answer:

Nature selects best suited organisms having behaviours that help in the survival of organisms in that environment.

Explanation:

Natural selection can shaped the behaviors that are learned by the organisms because these behaviours helped organisms in their survival. Those organisms will be selected by the nature which can withstand the changing environmental conditions. Organisms adopt different behaviours in order to survive harsh environmental condition and these behaviour shaped by the natural selection in that organism so that they survive and grow in that environment.

During frog gastrulation, involution occurs at the Group of answer choices endometrium. blastopore blastocoel. trophoblast. archenteron.

Answers

Answer:

blastopore

Explanation:

Involution is the second stage after invagination during frog gastrulation. Involution occurs at the blastopore when the marginal zone cells get to the tip of the blastopore, make an inward turn and then move along the inner exterior of the outer cells sheets.

This means that the cells found at the lip of the blastopore and always undergoing change and the first of these cells to develop into the dorsal lip are the endodermal cells. Next are the mesoderm cells that form the Notochord.

Distribution of Traits Quick Check

The factor that may contribute to a population maintaining Hardy-Weinberg equilibrium is there are no mutations in the DNA of the population. So, the correct option is A.

What do you mean by Mutation?

The sudden, stable, and inheritable changes in the genetic material of an organism, are called mutations.

There are some assumptions of Hardy-Weinberg equilibrium. They are.

The population is large.The members of the population mate randomly with each other.No migration occurs between populations.No new mutations are favorable. No survival or reproductive advantage.

Therefore, the factor that may contribute to a population maintaining Hardy-Weinberg equilibrium is there are no mutations in the DNA of the population.

Which statement is true of human cultures? O A. All human societies share the same cultural traits and practices. O B. Every human has a unique set of cultural traits and practices. O C. Culture includes a society's knowledge, customs, and achievements. O D. Cultures are groups of people united by blood relationships. SUBMIT​

Answers

Answer:

B. Every human has a unique set of cultural traits and practices.

Explanation:

Culture can be defined as the general way of life of a group of people living together in a particular location or society.

Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.

This ultimately implies that, culture are acquired and passed from one generation to another.

A cultural trait can be defined as the smallest characteristics of human activity (actions) that is mainly acquired socially and transmitted from one generation to another through various modes of communication.

This ultimately implies that, these unique behavioral informations or characteristics and beliefs acquired by people socially are transmitted from one individual or group of people to another.

Hence, the statement which is true of human cultures is that every human (race) has a unique set of cultural traits and practices that were acquired from the environment and society.
