Front

What is a genotype?

Back

A genotype is the genetic constitution of an individual, represented by the alleles inherited from its parents.

Front

What does homozygous mean?

Back

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

Front

What does heterozygous mean?

Back

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

Front

What is the genotype for a pea plant homozygous for round seeds (R) and heterozygous for yellow seeds?

Back

RRYy.

Front

What are Saurischian dinosaurs?

Back

Saurischian dinosaurs are a group of dinosaurs that are more closely related to birds than other dinosaur groups.

Front

What is the relationship between birds and Saurischian dinosaurs?

Back

Birds are descendants of Saurischian dinosaurs, making them closely related.

Front

What is the difference between the lysogenic and lytic cycles in viruses?

Back

In the lysogenic cycle, viral DNA integrates into the host's genome and replicates with it, while in the lytic cycle, the virus replicates and causes the host cell to burst.

Front

What is the lysogenic cycle?

Back

The lysogenic cycle is a viral reproductive cycle where the viral DNA is incorporated into the host's DNA and is replicated along with it.

Front

What is the lytic cycle?

Back

The lytic cycle is a viral reproductive cycle where the virus takes over the host cell's machinery to produce new viruses, leading to cell lysis.

Front

What is a phylogenetic tree?

Back

A phylogenetic tree is a diagram that represents evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.
