<span>It began with selective breeding in the ancient times where a population with desirable traits were bred with other population to achieve a desired set of traits. It then continued with the advance in the discovery of bacteria (Escherichia coli) and antibiotics. Then Watson and Crick discovered the structure of DNA. The latest advance being that of gene sequencing and gene editing tools. </span>
Answer:
The recombinant frequency between T and S is 18%;
The correct Sequence of genes is T-A-S
Explanation:
The table below shows the recombinant frequency between heterozygous height and nose morphology:
Tall-uptrend snout 40% Expected
Dwarf-downtrend snout 42% Expected
Dwarf-uptrend snout 9% Recombinant
Tall-uptrend snout 9% Recombinant
Sum Total 100%
To calculate the recombinant frequency; we have :
=9+9
=18%
Hence, the recombinant frequency between T and S = 18%
The determinant of the corect sequence of the genes is T-A-S
Answer: Management by Objectives.
Inheritance is the process by which traits are passed from the parents to their offspring. The basic unit of inheritance in human is the DNA. For traits to be passed from the parent to the offspring, the DNA in the cell must be duplicated and this happens through the process of cellular reproduction.
