Aplant is homozygous for flower color. its flowers are pink.

which conclusion is best supported by the information?

a. flower color is a recessive trait.

b. flower color is a dominant trait.

c. both parents had an allele for pink flower color.

d. only one parent had an allele for pink flower color.

The correct answer is A. Flower color is a recessive trait.

The recessive gene does not show its effect in heterozygous condition according to Mendel’s law of dominance. Thus, in heterozygous condition, dominant gene determines the phenotype for a trait. In this question a plant is homozygous for flower color. This indicates that pink flower determining gene can only be expressed in homozygous condition. Therefore, flower color is a recessive trait.  

b tumor cells have a cell wall instead of a membrane

explanation:

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.

answer >   yes we do, women; have three holes, urethral opening(pee hole, vagina, and the women pee/girls pee out of the urethra like the men do; only they have a single opening to pee/ejaculate.   (sorry if i'm too forward with this, but this is for a biology class, isn't it? )

hope that !         : )
