Stells [14]

Answer:

20 ( B )

Explanation:

Given data:

a and b are 10 map units apart

b and c are 20 map units apart

a and c = 30 map units apart

<em>condition </em>; Triple heterozygote testcrossed

number of progeny = 1000

<u>Determine the number of double crossover result </u>

P( crossover between a and b ) = 10/100 = 0.1

P( crossover between b and c ) = 20/100 = 0.2

p( double crossover ) = 0.1 * 0.2 = 0.02

hence number of double crossovers = number of progeny * 0.02

                                                              = 1000 * 0.02 = 20

Why do different individuals of the same species have different traits?
deff fn [24]

Individuals of the same species have different traits because they have different genes which code for different proteins. B would be the correct option.

<h3>Variations</h3>

Organisms of the same species can have different traits due to a difference in their proteins.

Genes are responsible for proteins and proteins are an expression of traits. Thus, with different proteins come different traits.

Hence, once there is a difference in the DNA sequence of organisms, different proteins will be produced, and different traits will be expressed.
