Answer: The answer is that the phenotypic ratio among phenotypes produced from an F1 X F1 dihybrid cross is 9:3:3:1.

Explanation:

Independent assortment of genes explains how alleles on different chromosomes arrange independently of one another during gamete formation.

So, a dihybrid cross involving TWO characters (e.g Seed color & seed shape) would have its respective alleles DISTRIBUTED whether dominant or recessive, for crossing to occur and yield varying proportion of offspring in the well spread ratio of 9:3:3:1; making it a consequence of independent assortment of genes

The early ancestors of horses showed the presence of digits on their limbs, while modern horses have hooves. What are likely pos
klio [65]

The correct answers are evolution, genetic mutation and selection.

The early ancestors of horses showed the pressence of digits and now the modern horses have hooves in their limbs. There could be many reasons for the pressence of hooves horses.

These could be due to the genetic mutations, which could have changed the shape of the digits in the limb. Sudden change in DNA can cause mutation and this mutation can change the phenotype of the horse.

There are chances that evolution took place over a period of time that changed the character in the horse.

Natural selection can also be one of the reason for the change in the phenotype of the digits on the limb of the horses.

Gel analysis of fragments in step 6 shows that even though the undigested DNA and DNA digested with HindIII are both 1000 bp, th
Soloha48 [4]

Answer:

Size of the band varied

Explanation:

In the given question, the options are not provided but based on the information provided in the question, it can be predicted.

When the DNA was digested by the HindIII, then the length of the digest came about 1000 bp and the undigested DNA was also found 1000 bp.

When both the bands were analysed by Gel electrophoresis then the bands do not run to the same distance therefore this shows that the size of both the bands was not equal and their size varied.

Thus, the size of the band varied is correct.
