Cell Cycle and Genetics

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene.

Front

What is Metaphase in the cell cycle?

Back

Metaphase is the stage in cell division where chromosomes align in the middle of the cell before being separated.

Front

In a heterozygous genotype, which allele is expressed in the phenotype?

Back

The dominant allele is expressed in the phenotype.

Front

In pea plants, how is the tall allele represented?

Back

Tall allele is represented as 'T' and the short allele as 't'.

Front

What phases occur during Interphase?

Back

The G1, S, and G2 phases occur during Interphase.

Front

What is the definition of a genotype?

Back

A genotype is the genetic makeup of an organism, representing the alleles inherited from parents.

Front

What is the definition of a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What is the role of the dominant allele?

Back

The dominant allele masks the effect of the recessive allele in a heterozygous genotype.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their traits even when only one copy is present, while recessive alleles require two copies to express their traits.

Front

What is the purpose of mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.
