Question

1. using the symbols from the above chart, write the allele symbols that would be present in the following homozygotes. next, indicate whether they are going to express the dominant or recessive trait.

	allele symbols	dominant or recessive?
terminal flowers	tt	recessive
white seed coats	tt	recessive
yellow seeds	yy	dominant
yellow pods	yy	dominant

Explanation:

Step1: Match trait to allele symbol

For each trait, identify the correct homozygous allele symbol (homozygous means two identical alleles; dominant traits use uppercase, recessive use lowercase).

1. Tall stemmed plants (dominant): $TT$
2. Terminal flowers (recessive): $tt$
3. White seed coats (recessive): $tt$
4. Yellow seeds (dominant): $YY$
5. Yellow pods (dominant): $YY$

Step2: Determine expressed trait

Homozygous dominant ($TT$, $YY$) expresses dominant trait; homozygous recessive ($tt$) expresses recessive trait.

1. $TT$ → Dominant
2. $tt$ → Recessive
3. $tt$ → Recessive
4. $YY$ → Dominant
5. $YY$ → Dominant

Answer:

Trait	Allele Symbols	Dominant or Recessive?
Terminal flowers	$tt$	Recessive
White seed coats	$tt$	Recessive
Yellow seeds	$YY$	Dominant
Yellow pods	$YY$	Dominant
