Q: In Mendelian genetics, what does the term 'homozygous' refer to?
Solution:
Homozygous refers to having two identical alleles for a particular trait, either dominant or recessive.
Steps: 5
Show Steps
Step 1: Understand that genes come in different versions called alleles.
Step 2: Know that alleles can be dominant or recessive.
Step 3: Realize that 'homozygous' means having two of the same alleles.
Step 4: Identify that these alleles can be both dominant (e.g., AA) or both recessive (e.g., aa).
Step 5: Conclude that being homozygous means you have two identical alleles for a specific trait.
