<span>Technology is one reason why the shire horse is in decline. With the main job that they did being farmwork, and many of these tasks being taken over by mechanized means, the number of breeders of these horses has declined and the number of horses therefore available has dipped, as well.</span>

Answer:
WILD TYPE= 425;
TAN-BARE= 425;
TAN= 75;
BARE= 75
Explanation:
Fifteen map units apart implies that 15% of the offspring are products of recombination.
Out of 1000 offsprings, therefore 15% of 1000= 0.15 × 1000=150
150 offsprings are products of recombination.
100-15 =85%
Therefore, 85% of the offspring are parental.
So, if tan-bodied, ware-winged female was mated with wild-type male resulting in F1 phenotypically wild-type females were mated to tan-bodied, bare-winged males.
The expected number of offsprings that are tanned but have normal wings would be:
Wild type= 50% of 850
0.50 × 850 = 425
Tan-bare= 50% of 850
0.50 × 850 = 425
tan= 50% of 150
0.50×150= 75
Bare= 50% of 150
0.50×150=75
The situation in which allele frequencies in the gene pool of a population remain constant is called. genetic equilibrium. The type of genetic drift that follows the colonization of a new habitat by a small group of individuals is called.
2. DNA is important to carry genes or genetic materials of the parents
