Answer:
Two DNA cells come together to form a whole new genome.
I think the phenotype of a genotype tt (from the question) will show shortness which homozygous with two similar alleles for shortness trait. Therefore; since the t trait is recessive over the T allele which is dominant, Tt, -will be a tall pea plane, TT- tall (homozygous), tT- tall ( heterozygous), tt -short (homozygous).
Answer:
D. IRIS
Explanation:
Generally in humans and also in most mammals and birds, the iris is a very small circular structure in the eye, responsible for controlling the diameter and size of the pupil and also with the amount of light reaching the retina.
finallly eye color is also known to be defined by that of the iris

The answer is :
B. A eukaryotic cell's nucleus contains the DNA or the genetic material of the cell.
The DNA has the necessary information for the cell's construction and the control of the synthesis tasks done by the cell. The nucleus is protected by the nuclear membrane. It surrounds the nucleus with a membrane with many pores.
Explanation:
The nucleus is a membrane-enclosed organelle located in most eukaryotic cells. The nucleus is the largest organelle in the cell and includes most of the cell's genetic information (mitochondria also contain DNA, called mitochondrial DNA, but it proceeds up just a small portion of the cell's overall DNA content. Inside its fully enclosed nuclear membrane, it contains the preponderance of the cell's hereditary material. This material is designed as DNA molecules, along with a family of proteins, to form chromosomes.
