Identify the type of variation in the polar population.

1 answer:

3 0

At the intraspecific population genetic level, polar bears have low protein variation (Allendorf et al. 1979; Larson et al. 1983) and variation comparable to other bears for mtDNA and microsatellite DNA (Cronin et al. 1991; Paetkau et al. 1995, 1997, 1999; Crompton et al.

Sandra drew an isosceles triangle that has an angle that measures 46 degrees. Which could be the measures of the other two angle

kipiarov [429]

Answer:

46 and 88° or 67 and 67°

Explanation:

An isosceles triangle has two sides of equal length and one other of a different length;

A triangle with such features also has 2 equal angles and one other;

If we consider that 46° is the angle that is not one of the two equal ones, then we can calculate the other two;

All angles in a triangle sum to 180, so:

180 - 46 = 134

The two remaining angles constitute 134° collectively;

If they are equal, each angle can be found like so:

¹³⁴/₂ = 67

Each of the two equal angles will be 67°;

Alternatively, if 46° is one of the two equal angles, then these two angles will be:
46 × 2 = 92

Then, the remaining angle can be found like so:

180 - 92 = 88

So the angles within the triangle are either:

46, 46 and 88°

46, 67 and 67°

Suppose that in unicorns, two autosomal loci interact to determine the type of tail. One locus controls whether a tail is presen

Nina [5.8K]

Explanation:

As you can see in the picture below, this is a dihybrid cross with a twist.

We can accomplish that mutually parentages are heterozygotes for both characters because the genotypes are

9 unicorns with curly tails (shown in green)

3 with straight tails (shown in red)

3 curly tales trait carriers with no tail (shown in dark blue)

1 straight tail trait carriers with no tail ( shown in light blue)

If this was an ordinary case of the dihybrid cross, we would get a 9:3:3:1 phenotype ratio.

However, since the first trait, the presence of the tail, is affecting the other trait, the trait texture, the ratio is altered.

$\frac{1}{4}$ of the offspring (genotypes tt C_ and tt SS) has no tail, therefore we cannot observe the texture of the tail (some of the tailless individuals have Curly alleles -blue squares marked with green, some of them have Straight alleles -blue square marked with red ).

Therefore, the altered ratio is $\frac{1}{2}$ curly tails, $\frac{1}{4}$ straight tales, $\frac{1}{4}$ tailless
