in monohybrid cross between a pure breed plant that produces blue flowers (BB)and a pure breed plant that produces white flowers.The f1 generation produces only blue flowers. By means of a labelled cross diagram,state the type of flower you will expect if the f1 generation is self pollinated
Answers
Answer: If the F1 generation is self-pollinated, 75% of the flowers will be blue, while 25% will be white.
Explanation:
Monohybrid cross between blue and white: BB x bbThe cross produces 100% Bb --> blue is dominant, so all the flowers will be blue. This is the F1 generation.If F1 is self-pollinated, it will be Bb x Bb.The cross will produce 25% BB, 50% Bb, and 25% bb.Since blue is dominant, 75% of the flowers will be blue, while 25% will be white.Pictures:
The first picture is the BB x bb cross.The second picture is the Bb x Bb cross.I don't know why the pictures are appearing sideways. If you click the rotate button at the top right of the pictures, you can turn them.

Black mice and tan mice are native species that are observed in a particular region. Human habitation in the region caused an invasive mouse species to enter the region. These mice are brown and share the same food requirements as black mice. Tan mice have different food requirements. How will this change affect the food web in the region? A. The availability of food resources for black mice and brown mice will decrease. B. The population of tan mice will decrease. C. The black mice and tan mice will compete for food resources. D. The tan mice and brown mice will compete for food resources.
Answers
Answer:
A
Explanation:
The correct answer would be that the availability of food resources for black mice and brown mice will decrease.
Since the food requirements of the black mice are the same as that of the invasive brown mice, the available food supply that used to be only for the black mice would now be shared by the two strains of mice. Hence, the available food for the two groups of mice will naturally decrease.
There is no sufficient information to conclude that the population of tan mice will decrease, hence, option B is incorrect.
The black mice and tan mice have different food requirements going by the information available in the illustration, hence, both cannot compete for food resources. Option C is, therefore, incorrect. In the same vein, option D is incorrect because the tan mice have different food requirements from the brown mice.
The only correct option is A.

pls help
Answers
Answer:
Errors in the human genetic code, which are called mutations, sometimes lead to the production of abnormal proteins that may cause disease, including autoimmune disease and malignancy.A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.

Which prediction about the offspring's body color is based on the properties of genetic reproduction?
O A The offspring can only express the trait of gray body color.
OB. The offspring can only have genes for the trait of gray body color.
O c The offspring can express either the gray or the black body color trait
O 0. The offspring are equally likely to have genes for the gray or black body color trait.
Answers
Why? - As we set the punnet square. We get the results, (2)GG and (2)Gg. GG = Gray and Gg = Gray.
The prediction about the offspring's body color is based on the properties of genetic reproduction, it can only express the trait of gray body color. The correct option is A.
What is the dominant and recessive gene?Recessive and dominant genes. Dominant/recessive interactions are the most frequent type of allele-allele interaction. When one (dominant) allele of a gene effectively outweighs the other (recessive) allele, the allele is said to be dominant.
Blood types and eye color are two instances of dominant/recessive gene interactions. Due to recessive inheritance, the disease can only be brought on by a pair of faulty genes. Carriers are individuals who have only one faulty gene out of the pair.
Therefore, the correct option is A. The offspring can only express the trait of gray body color.

B) The recombinant bacterium will not transcribe the human insulin gene because this gene is not normally found in the bacterial genome.
C) The recombinant bacterium will transcribe the gene but will be unable to translate the mRNA.
D) The recombinant bacterium will die because it has been exposed to foreign DNA.
Answers
Answer:
А) The recombinant bacterium will produce human insulin using its own transcription and translation machinery.
Explanation:
Recombinant DNA technologies refer to molecular biology techniques used to create chimeric DNA sequences by using genetic recombination techniques. The resultant recombinant DNA can further be used for the production of desired gene products (proteins) both in vitro and in living organisms. DNA recombinant techniques involve the insertion of desired DNA regions into an appropriate vector such as, for example, in a plasmid that is amplified in bacteria. For this purpose, the desired DNA fragment is inserted into a plasmid vector by digesting both the target DNA and plasmid insertion sites with an appropriate restriction enzyme. Subsequently, a DNA ligase is used to join both DNA fragments from their ends. Finally, the transformed bacterial (host) cells are selected to express the desired inserted gene.

In eukaryotes, general transcription factors A) are required for the expression of specific protein-encoding genes. B) bind to other proteins or to a sequence element within the promoter called the TATA box. C) inhibit RNA polymerase binding to the promoter and begin transcribing. D) bind to sequences just after the start site of transcription.
Answers
Answer:
B
Explanation:
The general transcription factors bind to other proteins or to a sequence element within the promoter region known as the TATA box.
Transcription is a biological process involving the synthesis of RNA from a DNA template. The process of transcription begins with the binding of an enzyme, the RNA polymerase, to the promoter region of a gene. Prior to that, however, a group of enzymes known as the transcription factors must bind to a specific sequence within the promoter region - the TATA box. The binding of the RNA polymerase signals the unwinding of the section of the DNA to complete the initiation complex.
The correct option is, therefore, B.
