Exploring Mendel's Laws of Inheritance

What was the common belief about inheritance in the 1800s using giraffes as an example?

• Giraffes learned to stretch their necks over time

• Giraffes' necks grew longer due to genetic mutations

• Only genetic traits can be inherited

• Traits acquired during life can be inherited

What decision did Gregor Mendel make that changed his career path?

• He took over his family farm

• He chose to enter a monastery

• He moved to Austria for his studies

• He decided to become a teacher

What was the unexpected result of Mendel's first genetic cross of pea plants?

• No seeds were produced

• All offspring had green seeds

• All offspring had yellow seeds

• The seeds were of mixed colors

What did Mendel use to study genetics?

• Fruit flies

• Bacteria

• Mice

• Pea plants

What does the term 'homozygous' refer to in genetics?

• An organism with two identical alleles

• An organism with two different alleles

• A recessive genetic trait

• A dominant genetic trait

What is the phenotype of an organism?

• Its genetic makeup

• Its physical appearance

• Its potential traits

• Its cellular structure

Which generation did Mendel find the recessive trait reappearing?

• F3 generation

• Parent generation

• F1 generation

• F2 generation

What does a heterozygous genotype consist of?

• No alleles

• One dominant and one recessive allele

• Two recessive alleles

• Two dominant alleles

According to Mendel's law of segregation, how are alleles passed to offspring?

• Both alleles from one parent are passed on

• Only dominant alleles are passed on

• One allele from each parent randomly

• Alleles are mixed before being passed on

What is Mendel's second law of inheritance?

• Law of segregation

• Law of independent assortment

• Law of dominant traits

• Law of genetic mutation
