Front

What are Sister Chromatids?

Back

Sister chromatids are identical copies of a chromosome, connected by a centromere, that are formed during DNA replication.

Front

How many chromosomes do daughter cells have after meiosis if the parent organism has 10 chromosomes?

Back

5 chromosomes.

Front

What is the genotype of a plant with round seeds (RR) crossed with a plant with wrinkled seeds (rr)?

Back

The offspring will all have the genotype Rr, resulting in 100% round seeds.

Front

What is the process of Crossing Over?

Back

Crossing over is the exchange of genetic material between homologous chromosomes during meiosis, leading to genetic diversity.

Front

What is the probability of a blue-eyed child from two brown-eyed parents (Bb)?

Back

25% chance.

Front

Define Homozygous.

Back

Homozygous refers to having two identical alleles for a particular gene, such as RR or rr.

Front

Define Heterozygous.

Back

Heterozygous refers to having two different alleles for a particular gene, such as Rr.

Front

What is a Punnett Square?

Back

A Punnett Square is a diagram used to predict the genetic outcomes of a cross between two organisms.

Front

What is the difference between Genotype and Phenotype?

Back

Genotype is the genetic makeup of an organism, while phenotype is the observable traits or characteristics.

Front

What does the term Allele mean?

Back

An allele is a variant form of a gene that can produce different traits.
