Answer:

Efficiency of Genomic sequencing of viruses

Explanation:

Due to ebola, scientist improved their research and development on sequencing viruses to provide a more efficient test kit.

Similarly, during coronavirus outbreak, this crucial advancemeny in technology allows the virus's genome to be sequenced to provide essential information for scientist to develop a vaccine or even medication to inhibit the virus

White feathers in canaries are dominant to yellow feathers. A heterozygous canary is crossed with a homozygous recessive canary.

Lera25 [3.4K]

2:4 homozygous recessive; 50% heterozygous.

Explanation:

I will be using the letter B to represent dominant alleles and b to represent recessive alleles.

If a canary is heterozygous, that means that it will have (Bb). Hetero, means different, so it will never be both (BB) or (bb).

If the other canary is homozygous recessive, it will be (bb). Homo, means the same, so it will never be (Bb). If the canary were homozygous dominant, it would be (BB).

I made a Punnett square to figure out the ratio and the percentage that is being asked in the question. As you can see, if you bring down the alleles from both of the parents accordingly, you will get...

2:4 of the offspring will be potentially homozygous recessive.

50% of the offspring will be heterozygous.

CH3OH + HOCH3 = CH3-O-CH3 + HOH Is this reaction an addition reaction or a dehydration reaction or synthesis or whatever? A. Add

bagirrra123 [75]

Answer:

B. Dehydration

Explanation:

Addition reaction is defined as the chemical reaction in which two different compunds combine together to form a new compund.

Dehydration reaction is defined as the chemical reaction in which water molecule (H2O) is removed from the reactant.

For example: RCO2H + R′OH ⇌ RCO2R′ + H2O

In the given equation: CH3OH + HOCH3 = CH3-O-CH3 + HOH

The reaction is showing dehydration because two molcules are combined aand water molecule is eliminated from the reactant.

Hence, the correct option is B. Dehydration.

Amiraneli [1.4K]

Answer:

F1 generation: RrUu, rrUU, rrUu, RrUU

25% : 25%: 25%: 25%

Ratios

genotype: 1: 1: 1: 1 ...(from punnet square)
phenotype: 1 : 1

Explanation:

Punnett squares are a diagrammatic way of deciding the characteristics of hybrid offspring created by crosses in genetic breeding. Parental genotypes and phenotypes are widely recognized, and all usually obey normal Mendelian ratios and inheritance.

Mendelian genetics focuses on the origin or heritability of characteristics. Such traits are packed into one's own gamete, acquired by themselves, and sometimes display superiority, where one's impact can mask those of another trait.

These are called the Law of Segregation, Independent assortment and Dominance respectively.

For this cross... Assuming:

Unattached lobes= dominant

Rolling tongue= dominant
Parent generation or P generation:

Gametes:

R → rolling dominant (R), non-rolling recessive (r)

U → unattached dominant (U), attached recessive (u)

P generation: RUrU× rUru

rolling, unattached × non-rolling, unattached

F1 generation: RrUu, rrUU, rrUu, RrUU

25% : 25%: 25%: 25%

Ratios

genotype: 1: 1: 1: 1 ...(from punnet square)
phenotype: 1 : 1

Half the offspring have unattached lobes and can roll their tongues while the other half have unattached lobes and cannot roll their tongues...

Each punnet cross is attached below
