Accepted Answer

### Question 1
# Brief Explanations:
During fertilization, a sperm (carrying half the chromosomes) and an egg (carrying half the chromosomes) combine to form a zygote with a full set of chromosomes. So the statement (assuming it's about chromosome number restoration) is True.
# Answer:
True

### Question 2
# Brief Explanations:
In Mendelian genetics, if Purple (P) is dominant over White (p), the genotype Pp has the dominant allele P expressed. So the phenotype is Purple flowers (since dominant allele determines the phenotype in a heterozygous state here, assuming complete dominance). Option a is correct.
# Answer:
a. Purple flowers

### Question 3
# Brief Explanations:
- The process of copying DNA to mRNA (transcription) occurs in the nucleus (where DNA is located).
- The process is transcription.
- The mRNA then travels to a ribosome (the site of translation) to be read for protein synthesis.
So Blank 1: nucleus; Blank 2: transcription; Blank 3: ribosome.
# Answer:
Blank 1: nucleus
Blank 2: transcription
Blank 3: ribosome

### Question 4
# Brief Explanations:
A dominant allele is not always beneficial. For example, a dominant allele causing a genetic disorder (like Huntington's disease) is harmful. So the statement is False.
# Answer:
False

### Question 5
# Brief Explanations:
Human twins (identical) share about 99.9% of their DNA, and even then, environmental factors also influence traits. The claim of 100% determination by genetics is false as environment plays a role.
# Answer:
False

### Question 6
# Brief Explanations:
- Translation is the process where mRNA is used to build proteins (polypeptides) at ribosomes.
- Meiosis is the process that forms sex cells (gametes) with half the number of chromosomes.
- Humans have 23 pairs of chromosomes (46 total), so sex cells get one from each of the 23 pairs (homologous pairs).
So Blank 1: translation; Blank 2: proteins; Blank 3: meiosis; Blank 4: pairs (homologous pairs).
# Answer:
Blank 1: translation
Blank 2: proteins
Blank 3: meiosis
Blank 4: pairs

### Question 7
# Brief Explanations:
A carrier with genotype Bb (where B is dominant, b is recessive) can pass the recessive allele (b) to offspring without expressing the recessive trait (since B is dominant, the carrier shows the dominant phenotype). So the statement is True.
# Answer:
True

### Question 8
# Brief Explanations:
- Heredity: d (passing of genetic info from parent to offspring)
- Allele: b (a variant form of a gene, organisms have two alleles for a gene)
- Genotype: e (the genetic makeup, represented by letters like BB, Bb, bb)
- Phenotype: a (observable traits from genotype + environment)
- Locus: c (specific location of a gene on DNA/chromosome)
So 1: d; 2: b; 3: e; 4: a; 5: c.
# Answer:
1: d
2: b
3: e
4: a
5: c

### Question 9
# Brief Explanations:
Farmers use selective breeding to develop crops with desirable traits (like larger fruit or disease resistance). Selective breeding involves choosing organisms with desired traits to breed. So the word is selective breeding.
# Answer:
Blank 1: selective breeding

### Question 10 (partially visible, assuming about which term means "same alleles"):
# Brief Explanations:
Homozygous means having the same alleles (e.g., AA or aa). If options include "Homozygous" (like option c if present as "Homozygous Homozygote" or similar, but based on context, the term for same alleles is homozygous. Assuming the option with homozygous is correct.
# Answer:
(Assuming the option with "Homozygous" is correct, e.g., if option is c. Homozygous Homozygote, then) c. Homozygous Homozygote (adjust based on exact options, but the term for same alleles is homozygous).
