Answer:
how are genes expressed for a particular trait?
Genes are expressed in two ways which could be either genotype or phenotype
genotype reflects the dominancy or recessives of a particular trait over another while phenotype entails the physical expression of such trait which could be height, color of skin among others
e.g
If P is purple while p is white
PP x Pp= PP, Pp, PP. Pp these are the genotype produced from the crossing of two parents which results into 2 homozygous gene and 2 heterozygous gene without any recessive gene
while the phenotype shows that all the offspring are Purple
Explanation:
Answer:
Explanation:
An increase in length of the shoot and the root is termed to as primary growth of a plant. It occurs as a result of cell division in the apical meristem. Secondary growth is identified by an increase in thickness or girth of the plant caused by cell division in the cambia or lateral meristems.
1) apical meristem- primary growth
2) cork cambium - secondary growth
3) elongation - primary growth
4) provides structural support - secondary growth
5) increases exposure to light - primary growth
6) increases vascular flow - secondary growth
7) growth in thickness - secondary growth
8) occurs in plants that live many years - both primary and secondary growth
9) occurs in plants that live only one year - primary growth
10) lateral meristem - secondary growth
11) vascular cambium - secondary growth.
