Question

trait dominant or recessive?
write the genotype for each individual (use the letter a)

1. is the trait dominant or recessive?

write the genotype for each individual (use the letter a)
making conclusions

1. if a child has an autosomal dominant trait, what can you say about the parents?
2. if two parents have an autosomal dominant trait, what can you say about their children?
3. if two parents have an autosomal recessive trait, what can you say about their children?
4. if two parents do not have an autosomal recessive trait, what can you say about their children?
5. can autosomal recessive traits skip generations?

Explanation:

Answer:

1. Dominant; 1: Aa, 2: aa, 3: aa, 4: Aa, 5: aa, 6: aa, 7: Aa, 8: Aa, 9: aa, 10: aa, 11: aa, 12: aa, 13: Aa, 14: aa, 15: Aa, 16: Aa, 17: aa
2. At least one parent must also have the trait.
3. The children may have the trait or may not have the trait (if both parents are heterozygous).
4. All of their children will also have the autosomal recessive trait.
5. Their children may have the trait (if both parents are carriers) or may not have the trait.
6. Yes, autosomal recessive traits can skip generations.
