Answer:
See
Explanation:
Given:
Brown allele (B) is dominant over the white allele (b).
It will be assumed that the alleles are not related to the X and Y chromosomes.
See attached diagram for details of the general case (for both homo-zygous and hetero-zygous parents)
For both parents hetero-zygous,
P1:
Genotype: Bb (100%)
Phenotype: brown (100%)
F1:
Genotypes : BB, Bb, bB and bb in equal proportions, i.e.
BB (25%), Bb (50%), bb (25%)
Phenotypes: 75% brown (from BB and Bb), 25% white (from bb)
THE DOG HAS 2 BROTHER is the example of discrete data.
The dog has 2 brothers.
<u>Explanation:</u>
Discrete data is the information that can be categorized into a classification. Discrete data is based on counts. only a few finite number of value is possible.
It consists of whole number that are counted rather than measured. It can be classified into two type, one is discrete and other is continuous data, where the discrete is countable of the object and the continuous is measurable one.
The dog has two brother is the example for discrete data because the number can be countable, remaining statement are continuous because they are measurable statement, it is always comes under the data continuous.
