As far as I know, radioactive dating is the measure of radioactive substances in a fossil or something. Like the fossils have a radioactive substance in them, it is the only thing that can show how long the fossils been aging, therefore being able to show the date. And thats how radioactive dating works, and that is how a paleontologist uses it

The gene for petal color in a flower has incomplete dominance, so that individuals with two A1 alleles (A1A1) are black, individ
Verdich [7]

Answer:

The probability of getting a mottled offspring is 0%. There is no A2 allele involved in the cross.

Explanation:

<u>Available data</u>:

  • The gene for petal color in a flower has incomplete dominance
  • Two A1 alleles (A1A1) express black color
  • Two A2 alleles (A2A2) express white color
  • One of each allele (A1A2) express mottled color

In a cross between two black flowers, there is no allele A2, there are just two alleles A1. So, the cross is:

Parental)    A1A1    x    A1A1

Gametes)  A1   A1       A1   A1

Punnet Square)     A1         A1

                   A1    A1A1     A1A1

                   A1     A1A1     A1A1

F1 Phenotypes: 100% black flowers

F1 Genotype: 100% A1A1

There are 0% of probabilities of getting a mottled offspring.

gavmur [86]

Competition factor are the species of birds responding to in the environment. Thus, the correct option is B.

<h3>What is competition?</h3>

If numerous bird species eat on the same tree species, there will be fierce competition for food. As a result of the competition, each species will seek out a certain portion of the plant to feed on, most likely the part of the plant where it will be easiest to outcompete the competitors for food.

As a result, we may deduce that the right response is "They have evolved to diverse niches as a result of competition."
