Segregation of alleles happens when the pair of alleles of each parent separate and only one allele passes from each parent on to an offspring. So if you had heterozygous tall plants and mated them (Tt x Tt), they would each separate into T and t, allowing each offspring to get either a T or a t from each parent. The possible genotypes would be TT, Tt and tt.

<span>Simple.
All of the millions of different life forms (the diversity of life) have come about by natural selection, whereby random mutations in the genes have either succeeded or failed.
But all life can be traced back to a common single-celled origin. Thus we have the unity of life where we (possibly) share more than 50 % of our DNA with a crocodile.eg:analogous organs, homologous organs.</span>
Answer:
A. Transport of materials in xylem
Xylem tissue helps in the transport of water and minerals
Water is transported upwards from roots to aerial parts of plants
Transport in xylem requires physical forces such as transpiration pull.
B. Transport of materials in phloem
Phloem tissue helps in the transport of food.
Transport of food in phloem requires energy in the form of ATP.
Food is transported in both upward and downward directions.
