Phenotype ratio= All red

b. Genotype ratio= 1/2 Bb: 1/2 bb

Phenotype ratio= 1/2 red: 1/2 silver black

c. Genotype ratio= All Bb

Phenotype ratio= All red

Explanation:

a. pure red x carrier red:

Genotype of parents: pure red (BB) x carrier red (Bb)

Genotype ratio of progeny= 1/2 BB: 1/2 Bb

Phenotype ratio of progeny= All red

b. carrier red x silver-black

Genotype of parents: carrier red (Bb) x silver-black (bb)

Genotype ratio of progeny= 1/2 Bb: 1/2 bb

Phenotype ratio of progeny= 1/2 red: 1/2 silver black

c. pure red x silver black

Genotype of parents: pure red (BB) x silver black (bb)

How can I use the analogy of building blocks to explain how genes relate to the diversity of life?

Andrei [34K]

Answer:

-Building blocks are the fundamentals to an overall result, in this case being the characteristics of a human being.

-This is related to genes as the variety of building blocks can make a completely different "outcome" just as a different gene can trigger a different characteristic.

- Without different building blocks, all outcomes will be the same, just as humans. So a variety of "building blocks" are needed for diversity.

Explanation:

Hope this helps.
