Explanation:

First Question:

In genetics, a homozygous dominant genotype has two identical dominant alleles (e.g., BB). Heterozygous has one dominant and one recessive (e.g., Bb), homozygous recessive has two recessive (e.g., bb). BB has two dominant alleles, so it's homozygous dominant. Also, BB is a genotype (the genetic makeup), but the options here - the first option "Homozygous Dominant" is more specific to the allele combination. Wait, but also "Genotype" is a term for the genetic makeup. Wait, let's re - evaluate. The question is "BB is...". Let's recall: Genotype is the genetic constitution of an individual (e.g., BB, Bb, bb). Homozygous dominant is when both alleles are dominant (BB). Heterozygous is Bb. Homozygous recessive is bb. But in the options, both "Homozygous Dominant" and "Genotype" are there. Wait, maybe the question is about the type of genotype. Wait, BB is a genotype, and it is homozygous dominant. But let's check the options. The options are: Homozygous Dominant, Heterozygous, Homozygous Recessive, Genotype. Wait, actually, BB is a genotype (the genetic makeup) and it is homozygous dominant. But maybe the intended answer is "Homozygous Dominant" or "Genotype"? Wait, no. Wait, the term "genotype" refers to the genetic makeup, so BB is a genotype. But also, BB is homozygous dominant. Wait, maybe there's a mistake in the options? Wait, no. Let's think again. The question is "A person is BB and has brown eyes, BB is...". So BB is the genotype (the genetic makeup) and it is homozygous dominant. But among the options, both are present. Wait, maybe the question is considering that BB is a homozygous dominant genotype, but the options have "Genotype" as well. Wait, no, let's check the definitions:

• Homozygous Dominant: Having two identical dominant alleles (e.g., BB).
• Heterozygous: Having two different alleles (e.g., Bb).
• Homozygous Recessive: Having two identical recessive alleles (e.g., bb).
• Genotype: The genetic constitution of an individual (e.g., BB, Bb, bb).

So BB is a genotype, and it is homozygous dominant. But the options include both. Wait, maybe the question is designed to have "Homozygous Dominant" as the answer? Or "Genotype"? Wait, no, let's see the second question: "A person is ee and has crumbly earwax, ee is...". ee is a genotype, and it is homozygous recessive. And "Genotype" is also an option. Wait, maybe the questions are asking for the type of genotype (homozygous dominant, etc.) and also, the genotype as a term. Wait, no, let's re - examine the first question. The options are:

1. Homozygous Dominant
2. Heterozygous
3. Homozygous Recessive
4. Genotype

BB is a genotype (the genetic makeup), and it is homozygous dominant. But which is the correct answer? Wait, maybe the question is considering that "Genotype" is the general term, but "Homozygous Dominant" is the specific type. But in the context of the question, maybe the intended answer is "Homozygous Dominant" or "Genotype"? Wait, no, let's check the second question. For ee: ee is a genotype, and it is homozygous recessive. The options are the same. So for ee, the answer would be "Homozygous Recessive" (and also "Genotype"). For Ff: Ff is a genotype, and it is heterozygous. So maybe the questions are asking for the type of genotype (homozygous dominant, heterozygous, homozygous recessive) rather than just "Genotype". So for the first question, BB is homozygous dominant. For the second, ee is homozygous recessive. For the third, Ff is heterozygous.

Wait, let's confirm:

• Homozygous Dominant: Two identical dominant alleles (e.g., BB)
• Heterozygous: Two different a…

The genotype ee consists of two identical recessive alleles. A homozygous recessive genotype has two of the same recessive alleles (like ee), heterozygous has different alleles, homozygous dominant has two dominant alleles. Also, ee is a genotype, but the question is about the type of this genotype. So ee is homozygous recessive.

Third Question:

The genotype Ff has one dominant (F) and one recessive (f) allele. A heterozygous genotype has two different alleles, homozygous dominant has two dominant alleles, homozygous recessive has two recessive alleles. Also, Ff is a genotype, but the question is about the type of this genotype. So Ff is heterozygous.

Answer:

s:

1. A. Homozygous Dominant
2. C. Homozygous Recessive
3. B. Heterozygous

(Note: Assuming the options are labeled as A: Homozygous Dominant, B: Heterozygous, C: Homozygous Recessive, D: Genotype for each question)
