The result would be twenty-five percent yellow and the blue ones will be fifty percent while green is twenty-five percent. If an F2 generation is derived from the two true-breeding parents which have the same trait for different characteristics. The recessive phenotype would be hundred percent of true breeding if they fertilized themselves. A recessive trait is expressed when the genotype is only homozygous recessive.

What might the shape of the skull and the supraorbital height tell us about each species?
Sladkaya [172]

Answer: The shape of the skull and the supraorbital height tell us the following about each species-

  • It can tell us about the intelligence of species and what all senses they were dependent upon for their survival
  • Most of the species possess similar skulls as mostly their structures are  oval shaped, sloped or round shaped.
  • Species have different food habits that is determined by the teeth, which vary from long and dull to short and dull.
  • Variation in teeth and face shapes could also be due to different geological locations.
  • In particular, the foramen magnum be located where the spine connects can be attributed to how the species gathered food through hunting and what kind of food they sought after.
  • Overall, the shape and the supraorbital height of each skull informs us the advantages and disadvantages each species had in its ecosystem.
  • It also tells what probable causes of death would be when the species died.

Dmitrij [34]

Answer:

The order of genes is- dp-cl-ap

Explanation:

The genes a be mapped on chromosome on the basis of the recombination frequency as the recombination shows that is the genes are linked or not.  In genetic mapping, 1 per cent recombination frequency is considered as 1 cM or map distance.

In the given question, the three gene distance are provided on the basis of which the gene can be mapped in the following manner:

1. Take the higher value of gene distance that is 42 m.u and plot them on the line,

2. now place second-highest value on the line that is 39 m.u.

3. The gene will be arranged in the order of dp-cl-ap.

4. dp--³---cl-----------³⁹---------------------ap.

Thus, dp-cl-ap is correct.
