BMST BMST - Basic Math and Science Genetics and Heredity Questions and Answers 2

Question 1

What is the process by which a DNA molecule makes an identical copy of itself?

Accepted Answer

Replication

Answer

DNA replication is the process that duplicates the DNA double helix before cell division.

Question 2

Which inheritance pattern results in a blended phenotype in heterozygotes (e.g., red × white = pink)?

Accepted Answer

Incomplete dominance

Answer

Incomplete dominance produces an intermediate phenotype because neither allele is fully dominant.

Question 3

A person with blood type AB carries which combination of alleles?

Accepted Answer

One IA and one IB allele

Answer

Blood type AB results from inheriting one IA allele and one IB allele, both of which are expressed (codominance).

Question 4

What is a mutation?

Accepted Answer

A permanent change in the DNA sequence

Answer

A mutation is a heritable change in the nucleotide sequence of DNA that can alter gene function.

Question 5

Which cells carry genetic information from one generation to the next?

Accepted Answer

Gametes

Answer

Gametes (sperm and egg cells) are the reproductive cells that transmit genetic information to offspring.
