the passage below describes the same species of fish. in a species of fish, some fish have long fins and some fish have short fins. the allele for long fins (f) is dominant over the allele for short fins (f). in a group of these fish, one fish has the genotype ff and has long fins. another fish has the genotype ff and has short fins. these two fish mate and produce many offspring. select all the possible genotypes an offspring could have. ff ff ff select all the possible phenotypes an offspring could have. long fins short fins

the passage below describes the same species of fish. in a species of fish, some fish have long fins and some fish have short fins. the allele for long fins (f) is dominant over the allele for short fins (f). in a group of these fish, one fish has the genotype ff and has long fins. another fish has the genotype ff and has short fins. these two fish mate and produce many offspring. select all the possible genotypes an offspring could have. ff ff ff select all the possible phenotypes an offspring could have. long fins short fins

Answer

Explanation:

Step1: Set up Punnett - square

The parents have genotypes $Ff$ and $ff$. The gametes from $Ff$ parent are $F$ and $f$, and the gametes from $ff$ parent are all $f$.

Step2: Fill in Punnett - square

F f
f Ff ff

Step3: Determine genotypes

From the Punnett - square, the possible genotypes of the offspring are $Ff$ and $ff$.

Step4: Determine phenotypes

Since $F$ (long fins) is dominant over $f$ (short fins), $Ff$ has long fins and $ff$ has short fins. So the possible phenotypes are long fins and short fins.

Answer:

Possible genotypes: B. $Ff$, C. $ff$ Possible phenotypes: A. long fins, B. short fins
