Question

part 3: use the table above to write genotype(s) for these phenotypes

1. heterozygous tall antlers
2. red nose
3. black nose
4. cannot fly
5. homozygous tall antlers
6. can fly
7. heterozygous non - flyer
8. homozygous dominant nose

Explanation:

To solve this, we assume standard Mendelian genetics where:

• For "tall antlers", let the dominant allele be \( T \) and recessive \( t \). Heterozygous is \( Tt \), homozygous tall is \( TT \).
• For "nose color", assume red (\( R \)) is dominant, black (\( r \)) recessive. Red nose: \( RR \) or \( Rr \); black nose: \( rr \); homozygous dominant nose: \( RR \).
• For "flying", assume can fly (\( F \)) dominant, cannot fly (\( f \)) recessive. Can fly: \( FF \) or \( Ff \); cannot fly: \( ff \); heterozygous non - flyer (non - flyer is recessive, so heterozygous for non - flyer would be \( Ff \) where \( f \) is non - flyer allele? Wait, no: non - flyer is \( ff \), heterozygous non - flyer would be if non - flyer is recessive, but heterozygous would have one dominant and one recessive. Wait, maybe "can fly" is dominant (\( F \)), "cannot fly" is \( ff \). Then heterozygous non - flyer: non - flyer is \( f \), so heterozygous non - flyer would be \( Ff \) (but \( F \) is fly, \( f \) is non - fly). Wait, maybe the problem has:
• 12. Heterozygous tall antlers: \( Tt \) (assuming \( T \) dominant for tall)
• 13. Red nose: \( RR \) or \( Rr \) (if red is dominant)
• 14. Black nose: \( rr \) (if black is recessive)
• 15. Cannot fly: \( ff \) (if cannot fly is recessive)
• 16. Homozygous tall antlers: \( TT \)
• 17. Can fly: \( FF \) or \( Ff \) (if can fly is dominant)
• 18. Heterozygous non - flyer: Let non - flyer be \( f \), so heterozygous non - flyer would be \( Ff \) (since non - flyer is recessive, heterozygous has one \( F \) (fly) and one \( f \) (non - fly))
• 19. Homozygous dominant nose: \( RR \) (if red is dominant, \( R \) is dominant allele for nose)

Answer:

s:

1. \( Tt \)
2. \( RR \) or \( Rr \)
3. \( rr \)
4. \( ff \)
5. \( TT \)
6. \( FF \) or \( Ff \)
7. \( Ff \)
8. \( RR \)
