Assume in otters short hair (L) is dominant to long hair (l) and black hair (B) is dominant to brown (b). If you found a black s

Georgia [21]

Answer:

llbb

Explanation:

The genotype of the black, short-haired otter could be determined by testing-crossing with a brown, long-haired otter whose genotype would be llbb.

Analysis of the resulting zygote from the cross would give an indication of the genotype of the otter - whether it has two dominant alleles each for the black, short-hair traits or heterozygous.

If the otter has two dominant alleles for the two traits, all the resulting zygote from the test-cross would have black, short-hair, but if it is heterozygous, a mixed phenotype set of zygote would be obtained.

A locus that affects susceptibility to a degenerative brain disease has two alleles, V and v. In a population, 16 people have ge

Pie

Answer:

Yes, the population is evolving

Explanation:

Hardy-Weinberg equilibrium states that a population is not evolving if it is in hardy weinberg equilibrium as the alleles frequency do not change over time in generations.

In mathematical equation, the genotype frequency will be -P²+2Pq+q²=1 and allele frequency will be p+q=1, where p = dominant allele and q will be recessive allele.

In the question, since the observed genotype are-

P² - VV= 16

2Pq- Vv- 92

q²- vv- 12

1. Calculate allele frequency

Now we will calculate if the expected value is same or close or not.

We will calculate allele frequency

Population has 120 individuals which means it has - 240 alleles.

In which V (p) will be- 32 +92= 124 allele

p- dominant allele/ total allele= 124/ 240 = 0.52

P= 0.52

q will be 1-0.52= 0.48

2. Expected genotype frequency

Now we will calculate expected genotypic frequency.

P²- 0.52 X 0.52= 0.27

2Pq = 2 x 0.52x 0.48 = 0.5

q²= 0.48 x 0.48 = 0.23

3. Expected progeny

P²= 0.27 x 120= 32 VV

2Pq= 0.5 X 120= 60 Vv

q²= 0.23 x 120= 28 vv

Since the observed value is not equal to the expected value therefore the population is not in Hardy- Weinberg equilibrium and the population is evolving.

Thus, Yes, the population is evolving is correct.

What differences do you see in the molecular shape of CO2 and NH3?

VMariaS [17]

The NH3 molecular geometry (molecular shape) is trigonal pyramidal. The NH3 bond angles are 107 degrees because the hydrogen atoms are repelled by the lone pair of electrons on the Nitrogen atom.
