Question 1

We often hear people talk about family traits and how they seem to skip a generation, according to Mendel what has happened?

Vesnalui [34]

This family trait that skips a generation comes from an autosomal recessive trait or as Mendel called as hidden non-dominant trait. Offsprings have a dominant and recessive trait which comes from both parents. Recessive trait appears only when two offspring with same recessive trait blends. This happens in self-fertilization. In the human population, marriage is prohibited between offsprings, thus having recessive trait is only imminent when cousins are married.

Why is fishing for some kinds of ocean fish controlled by laws?

lora16 [44]

C is the answer. Due to the current state of the world economy; people, if left to their own devices, would fish as much as possible so they can sell their fish to make money. Current technology means we can catch as many fish as we want (trawlers etc.). The problem with this is that there is only a finite amount of fish in the sea. If we were to fish them without limits in place, we could cause them to go extinct.

If a population with two alleles is at Hardy-Weinberg equilibrium ad the frequency of one allele is 0.7, what is the heterozygot

Vinil7 [7]

Answer:

B. 0.42

Explanation:

Since the two alleles are at Hardy-Weinberg equilibrium, the sum of the frequency of two alleles will be one. If the frequency of a dominant allele is "p" and that of the recessive allele is "q", then p+q=1

According to the given information, the frequency of one allele in the population is= 0.7

This means that the frequency of the other allele would be= 1-0.7 = 0.3

Frequency of heterozygote in the population =2pq = 2 x 0.7 x 0.3 = 0.42

Natalka [10]

between an animal cell and a plant cell there are some parts that are similar and carry out the same function like:

both have cytoplasm which holds the protoplasm(the living part of the cell)

both have a nucleus which carries out all cell activities and holds threads of DNA called chromosomes

both have a mitochondria which is the power house of the cell

both have golgi bodies which modify and carry proteins from sites of synthesis to sites of reaction
