Answer:

The Punnett square is a square diagram that is used to foretell the genotypes of a particular cross or breeding experiment. The diagram is used by biologists to determine the possibility of an offspring having a precise genotype.

Answer:

A Punnett square is a diagram used to determine the statistical likelihood of each possible genotype of the offspring of two parents for a given trait or traits. Reginald Punnett was applying the laws of probability to work pioneered by Gregor Mendel in the mid-1800s.

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.
