Answer:

DNA ⇄ RNA → PROTEINS.

Explanation:

Central dogma explains the flow of genetic information of the living organism. The DNA is converted to RNA by transcription and further into protein product by the process of translation. DNA can increase its number by replication process.

Retroviruses do not follow the central dogma and they have the ability to convert the RNA into the DNA molecule by the enzyme reverse transcriptase. Their central dogma is as follows:

DNA ⇄ RNA → PROTEINS.

Thus, the answer is DNA ⇄ RNA → PROTEINS.

In horses, black color (B) is dominant over chestnut color (b). Find the genotype and phenotype ratios of a cross between a hybr
valentina_108 [34]

Answer:

Phenotype: 2:2 or 1:1 / Genotype: 2:2 or 1:1 / 50% probability for chestnut color

Explanation:

If we put the two horses' genotypes in a Punnett square:

         <u> B          b</u>

<u>b</u>        Bb        bb

<u>b</u>        Bb        bb

The phenotype is describing the ending color of the offspring, where 2 of the 4 will be brown (Bb) and 2 of the 4 will be chestnut (bb), resulting in a 2:2 ratio. Genotype only refers to the alleles, where 2 of the 4 will be hybrid (Bb) and 2 of the 4 will be homozygous recessive (bb), again resulting in a 2:2 ratio. There is only a 50% chance that the offspring's phenotype will be chestnut color (bb) because the chestnut allele is recessive.
