2025 3rd Quarter Biology Assessment Review

Front

What is the purpose of crossing over during prophase 1 of meiosis?

Back

To create genetic diversity.

Front

What are the possible offspring genotypes when crossing a parent with AB type blood and a parent with type O blood?

Back

50% Type A, 50% Type B.

Front

Which codon does NOT code for Arginine?

Back

UGA.

Front

What is the probability of a white offspring when crossing a homozygous red flower (RR) with a homozygous white flower (rr)?

Back

0% chance of white offspring.

Front

What is the probability of a pink offspring when crossing a homozygous red flower (RR) with a homozygous white flower (WW) in incomplete dominance?

Back

100% chance of pink offspring.

Front

Define meiosis.

Back

A type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes.

Front

What is genetic diversity?

Back

The variety of genetic characteristics within a population, which is essential for evolution and adaptation.

Front

Explain complete dominance in genetics.

Back

A form of inheritance where one allele completely masks the effect of another allele.

Front

What is incomplete dominance?

Back

A genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype.

Front

What is a genotype?

Back

The genetic constitution of an individual, represented by alleles.
