Answer:
Regarding the genotype and phenotype of the original parents they are known by the name of parental classes. These parental classes have appeared of the genotype are classified as homozygous or heterozygous.
Explanation:
While the reciprocal classes are also the genotypes and phenotypes of the crosses. These reciprocal classes are personified if the crossing occurs between the homozygous alleles. This is due to the fact that the chromosomal part is exchanged in the two chromosomes, since the cross products are the same as the products that are formed in the parent classes, this occurs in a phenomenon known as homozygosity.
In the event that the crossover occurs in a heterozygous allelic tetrad, then an exchange between the different chromosomal parts will occur, resulting in recombinant alleles. In this particular case, the parenting classes cannot be the same. This phenomenon is known as heterozygosity.

GAS EXCHANGE: the intake of Oxygen and the expulsion of Carbon dioxide. In the capillaries of the alveoli, oxygen travels due to the concentration gradient into those capillaries. Carbon dioxide is then expelled from those capillaries.
RESPIRATORY MEDIUM: is air for animals and water for fish. It is basically the substance through with living animals receive their oxygen.
RESPIRATORY SURFACE: is where the gaseous exchange takes place. The oxygen and carbon dioxide move across the respiratory surface entirely by diffusion.
Answer:
Scientists first discovered chromosomes in the nineteenth century, when they were gazing at cells through light microscopes. But how did they figure out what chromosomes do? And how did they link chromosomes — and the specific genes within them — to the concept of inheritance? After a long period of observational studies through microscopes, several experiments with fruit flies provided the first evidence.
Answer:
16.28
Explanation:
because if we multiply the bothvalues in the triangle format when thes are cancelled out the remaining is the displacement
