8. In chickens, brown feathers are dominant over red feathers. Suppose we cross two heterozygous chickens.
devlian [24]

Answer:

Crossing two chickens heterozygous for the trait feather color, when brown feathers are dominant over red feathers, will produce offspring with brown and red feathers in a brown:red phenotypic ratio of 3:1.

Explanation:

Knowing that in chickens brown feathers are the expression of the dominant allele (B) and the recessive allele is red (b), crossing two heterozygous individuals (Bb) will result in offspring that are likely to have brown or red feathers.

The cross can be represented by a Punnett Square:

<u>Bb X Bb cross </u>

alleles     B    b

B             BB Bb  

b             Bb bb

Where the result is:

<u>Genotypes</u>:  

  • Bb, 50%
  • BB, 25%
  • bb, 25%

<u>Phenotypes</u>:

  • Brown feathers, 75%
  • Red feathers, 25%.

In this case, the probability of having brown or red feathers is 3:1.

What was Robert Brown looking at through a microscope when he found evidence of the 1827 scientific concept named in his honor?
Alexxx [7]
He was looking through a microscope at particles trapped in cavities inside pollen grains in water. The concept of Brownian motion is named after him. This is the random motion of particles suspended in a fluid, liquid or gas resulting from their collision with the fast-moving molecules. Here, the patterns of motion of the particles are typically alternations between random fluctuations in a particle's position inside a fluid sub-domain with a relocation to another sub-domain. Each relocation is followed by more fluctuations within the new closed volume.
