<span>This is the descending pathway. These are the neurons that allow for lower motor neurons to activate movement in the appropriate areas. These are fairly long neurons, having no synapses until they reach the lower neurons in the spinal cord.</span>
Or they could have evolved to adapt to their environment. Because of these mutations, they’re more beneficial to their species and can survive.
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:
The behavior of chromosomes during meiosis and fertilization is responsible for most of the variation that arises each generation during sexual reproduction. Independent assortment of chromosomes contributes to genetic variability due to the random orientation of tetrads at the metaphase plate. or Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I .
