Question
What does heterozygous mean?
- A creature with the same genes for a trait (TT or tt)
- An organism with distinct genes for a trait (Tt)
- When neither gene is totally dominant, the progeny is a combination of both
- The many variations of a characteristic (hair color—> brown, blonde, red)
Hint:
An organism with distinct genes for traits.
The correct answer is: An organism with distinct genes for a trait (Tt)
Every individual has two alleles or a single gene. When the alleles are the same, the condition is called homozygous and when the alleles are different, they are heterozygotes.
Hence, heterozygous is an organism with distinct genes for a trait (Tt)
