Question

dominant trait: c (circular flower)
recessive trait: c (square flower)
possible genotypes:
possible phenotypes:

1. dominant trait: r (round seed)

recessive trait: r (wrinkled seed)
possible genotypes:
possible phenotypes:

1. dominant trait: w (white fur)

recessive trait: w (black fur)
possible genotypes:
possible phenotypes:

1. dominant trait: t (tall height)

recessive trait: t (short height)
possible genotypes:
possible phenotypes:

Explanation:

• Genotypes: Genotypes are the genetic combinations. For a single - gene trait with alleles (e.g., \(A\) and \(a\)), the possible genotypes are \(AA\) (homozygous dominant), \(Aa\) (heterozygous), and \(aa\) (homozygous recessive).
• Phenotypes: Phenotypes are the observable traits. Since the dominant allele masks the recessive allele, \(AA\) and \(Aa\) will show the dominant phenotype, and \(aa\) will show the recessive phenotype.

Answer:

• 3. Dominant trait: \(R\) (round seed), Recessive trait: \(r\) (wrinkled seed)
• Possible Genotypes: \(RR\), \(Rr\), \(rr\)
• Possible Phenotypes: Round seed (\(RR\), \(Rr\)), Wrinkled seed (\(rr\))
• 4. Dominant trait: \(W\) (white fur), Recessive trait: \(w\) (black fur)
• Possible Genotypes: \(WW\), \(Ww\), \(ww\)
• Possible Phenotypes: White fur (\(WW\), \(Ww\)), Black fur (\(ww\))
• 5. Dominant trait: \(T\) (tall height), Recessive trait: \(t\) (short height)
• Possible Genotypes: \(TT\), \(Tt\), \(tt\)
• Possible Phenotypes: Tall height (\(TT\), \(Tt\)), Short height (\(tt\))
