25%

crossing two heterozygous plants would look like this Pp x Pp

                      P     p

P              PP        Pp

p             Pp          pp

what this means is that the capital P isdminant so thats what will show is the dominant purple petal whereas lower case p is the ressecive white petal

this means 25% of offspring will be white :)

Which statement about inheritance is true? Girls get most of their traits from their moms; boys get most of their traits from th
notka56 [123]

Answer:

The correct answer is the third statement.

Explanation:

In humans, the males possess one X and one Y chromosome, while the females possess two X chromosomes. Thus, the female always donates X chromosome to the gamete. In any case, the female always generates a similar kind of gamete. While the male either pass X or the Y chromosome to the progeny.  

When the gamete with the X chromosome combines with the female gamete than the offspring would possess XX chromosomes and will be a female. On the other hand, when the gamete comprising the Y chromosome combines with the female gamete than the offspring would possess the XY chromosome and will be a male. Thus, it is the father who determines the gender of the offspring.
