Question

After completion of the cell, you would expect to have which of the following?

	a.	four haploid cells, each with the same amount of genetic material but with different genetic information
	b.	two diploid cells, each with the same amount of genetic material and the same genetic information
	c.	four diploid cells, each with the same amount of genetic material and the same genetic information
	d.	two diploid cells, each with the same amount of genetic material but with different genetic information
	e.	a diploid zygote

All the offspring of a cross between a red-flowered plant and a white-flowered plant have pink flowers. This means that the allele for red flowers is ______ to the allele for white flowers.

	a.	pleiotropic
	b.	dominant
	c.	incompletely dominant
	d.	codominant
	e.	recessive

Answer 1

1.

A is correct for meiosis.

B is correct for mitosis.

Cell division is the process by which a cell divides itself.

Mitosis is a type of equational division in which a parent cell divides to give rise to two daughter cells. Both parent cell and daughter cells are diploid. They are genetically identical to each other.

Meiosis is a type of reductional division in which a parent cell divides to give rise to four haploid cells. The parent cells and daughter cells are different from each other.

2. Incomplete dominance

Incomplete dominance is a type of non mendelian inheritance in which the dominant allele is incompletely dominant over the recessive allele. Because of this, heterozygotes show intermediate phenotype.

RR = red

rr = white

Rr = pink
