HELP !
Mendel made crosses between pure-breeding tall pea plants with purple
flowers and pure-breeding short pea plants with white flowers. The alleles for
a tall height and purple flowers were dominant. This cross is written as
A. TtPpx TtPp
в. TTppx ttPP
с. Ttppx TtPP
D. TTPPx ttpp

D

Explanation:

He bred two true-breeding strains initially. That means the alleles were homozygous for each gene.

Let's use Tt to represent the height allele: T means tall, t means short; the dominant allele gets the capital letter.

Let's use Pp to represent the flower color allele: P means purple, p means white.

A pure-breeding tall, purple plant would be TTPP.

A pure-breeding short, white plant would be ttpp.

So the cross is D. TTPP x ttpp.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus. this is so because calcium carbonate is the main component in the shells.
