Explanations: answer key for all 10 questions

Q1: Who is called the father of genetics?
Answer: Gregor Mendel
He studied inheritance in the 1860s.
Q2: Which plants did Mendel study?
Answer: Pea plants
He tracked traits like flower color and seed shape.
Q3: What are alleles?
Answer: Different versions of a gene
Each person has two alleles for most genes.
Q4: If one allele hides another, it is called what?
Answer: Dominant
The hidden one is recessive.
Q5: What tool predicts offspring traits?
Answer: Punnett square
It was devised by Reginald Punnett.
Q6: What is an organism's physical appearance called?
Answer: Phenotype
Genotype is its genetic makeup.
Q7: Which chromosomes do most human males have?
Answer: XY
Females typically have XX.
Q8: Why is red-green color blindness more common in males?
Answer: The gene is on the X chromosome
Males have only one X.
Q9: What is a mutation?
Answer: A change in DNA sequence
Some are harmful, some helpful.
Q10: When was Mendel's work rediscovered?
Answer: 1900
Three scientists found it independently.

Genetics Trivia – How Traits Are Inherited

Genetics studies how traits pass from parents to offspring. In the 1860s, Gregor Mendel, a monk in Brno, bred thousands of pea plants and discovered that traits are inherited in predictable patterns through units we now call genes.

Each gene can have different versions, called alleles. Dominant alleles show their effect even with one copy, while recessive ones need two. Punnett squares help predict the chances of offspring traits.

Modern genetics links Mendel's laws to DNA and chromosomes. It explains inherited conditions, helps breed crops and animals and supports medicine through genetic testing and therapies.
