Lots of minerals have the same colour as another. Also, one mineral can be different colours as well. I hope this had helped you.

A population of 100 tigers has 30 with horizontal stripes. Using pedigrees, you ascertain that horizontal striping is caused by

bixtya [17]

Assuming that this population is in Hardy-Weinberg equilibrium, we can sayt that the probability that, given enough time, all tigers in the population will have horizontal stripes is 30% = 0.3.

--------------------------

Available data:

Population size, N = 100 tigers
Number of Tigers with horizontal stripes = 30
Horizontal stripes is caused by an autosomal recessive mutation.

We need to know the probability that all tigers in the population will have horizontal stripes, which is the recessive phenotype.

We assume that the population is in Hardy-Weinberg equilibrium, so there should be no evolution.

Since the population is in H-W equilibrium, the allelic, genotypic and phenotypic frequencies will remain the same generation after generation.

Now, we will calculate the allelic and genotypic frequencies of horizontal striped individuals in the population.

There are 100 individuals, and only 30 have horizontal stripes.

So, the phenotypic frequency, F(HS) is 30/100 = 0.3 = 30%

Since this is a recessive phenotype, this value equals the genotypic frequency, F(hh) = 30%

Finally, we can get the allelic frequency by taking the square root of this value.

F(hh) = q² = 0.3

f(h) = q = √0.3 = 0.55 = 55%

According to these calcs, the probability for the fixation of the recessive allele is 55%, and the probability that all individuals express the recessive horizontal stripes phenotype is 30%.

Replication is said to be semi-conservative. What does this mean about the chain being made?

kirill [66]

Answer:

Explanation: Replication is a semiconsecutive process this means that the strands of the DNA molecule separate to form two separate templates which will then combine with nucleotides following the complementarity base sequence to form two new daughter DNA

Describe how a plant regulates water loss through a feedback mechanism that involves guard cells

kumpel [21]

Guard cells close up to prevent water loss. These guard cells will automatically open up if there is a need of water to go out of the cell. An open stomate allows water to leave through transpiration, guard cells control the opening and closing of a stomata, stomates will close to reduce water loss and By opening and closing the stomata on the underside of the leaves.
