The migratory orientation of the Indigo Buntings can be primarily attributed to the species' accurate reading from their exposure to sky patterns and stars in the night sky which makes them move southward compared to other species. The study was pioneered by prominent zoologist Emlen.

<span>He is at an increased risk for sudden infant death. Since he is sleeping on a mattress that might inhibit his breathing, as well as having respiratory issues that might do the same (along with parents who are smoking, which will only inhibit proper respiration further), he will need to be constantly checked to make sure he is sleeping properly.</span>

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.
