Answer:

The correct answer is option A, that is, convergent evolution.

Explanation:

The convergent evolution in evolutionary biology refers to the phenomenon in which the organisms that are not closely associated, that is, not monophyletic, autonomously evolve identical characteristics as a consequence of having to amend to ecological niches or identical surroundings.  

For example, the evolution of lungs and gills that serves similar functions in distant organisms is an illustration of convergent evolution.

The Lincoln family has 3 children, 1 girl and 2 boys. What is the probability that their 4th child will be a boy?
goldfiish [28.3K]

Answer:

1/2

Explanation:

You have a 1/2 chance of having a boy and a 1/2 chance of having a girl.

Unless the question specifies whether or not there is a mutation present with the male parent, it is safe to assume there is a 50/50 shot of having a boy or girl.

A population is made up of individuals where 77 have the A1A1 genotype, 65 have the A1A2 genotype, and 123 have the A2A2 genotyp
lana [24]

Answer:

Frequency of allele A1- 0.41

Explanation:

In Hardy weinberg equilibrium,

P refers to the dominant allele

q refers to the recessive allele

The allele frequency will be p+q=1

The genotypic frequency is- P²+q²+2pq=1

P²= genotype of dominant trait ( A1A1)- 77

2pq= genotype of heterozygotes (2pq)- 65

q²= genotype of recessive trait (A2A2)-  123

Total number of offsprings= 77+  65+ 123

                                            = 265

Now to calculate allele frequency of A1=

\dfrac{\text{number of A1A1 offspring}}{ \text{total number of offspring}}+\dfrac{1}{2}(\dfrac{\text{number of A1A2 offspring}}{\text{total number of offspring}})

= 77/265 + 1/2( 65//265)

=  0.290+ 0.122

= 0.413

Thus, 0.41 is correct.
