Assuming dragon genetics follows the same rules as fruit flies, what ratio of genotypes would you expect if the genes were not l
andrew11 [14]

Assuming dragon genetics follow the same rules as fruit flies, we would get the same possible genotype for all 16 offspring provided that the genes are not linked.

Considering dragon genetics, flame eyes (F) are dominant to blue eyes (f) and burbling (B) is dominant to whistling (b).

Now, a dihybrid cross between two homozygous blue-eyed, whistling dragons will yield 16 offspring all with the same possible genotype .i.e. homozygous blue-eyed, whistling type.

Morgan through experiments on fruit flies observed that when the two genes in a dihybrid cross were situated on the same chromosome, the proportion of parental gene combination were much higher than the non-parental type.

He attributed this due to the physical association or linkage of the two genes and coined the term 'linkage' to describe the physical association of genes on a chromosome. The term 'recombination' is to describe the generation of non-parental gene combination.

Which group of hormones is responsible for the developments during puberty
zepelin [54]
Gonadotropin-releasing hormone, luteinizing hormone (LH for short) and follicle-stimulating hormone (FSH for short).

EXPLANATION

When your body reaches a certain age, your brain releases a special hormone that starts the changes of puberty. It's called gonadotropin-releasing hormone, or GnRH for short. When this hormone reaches the pituitary gland, it releases two more hormones into the bloodstream: the LH and FSH. Although boys and girls do have these hormones, it depends on their sexual orientation the way these hormones work.

Lila is a track and field athlete. She must complete four laps around a circular track. The track itself measures 400 meters fro
tekilochka [14]

Answer: Her speed is 4.4 m/s, and her velocity is 0 m/s.

Explanation:

Formulae :\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}

\text{Velocity}=\dfrac{\text{Displacement}}{\text{Time}}

Given: Length of track start to finish=  400 meters

After completing its 4 laps, total distance covered = 400 × 4 = 1600 meters

Time taken by Lila =   6 minutes

= 6 × 60 seconds      [There are 60 seconds in 1 minute.]

= 360 seconds  

Then, \text{Speed}=\dfrac{1600}{360}=\dfrac{40}{9}m/s

= 4.44\ m/s

But from start to finish displacement = 0 m   [displacement is the shortest distance between starting point to the finishing point]

So, \text{Velocity}=\dfrac0{360}=0\ m/s

Hence, Her speed is 4.4 m/s, and her velocity is 0 m/s.
