Answer:
Therefore, 98% of the US population have no alleles for PKU
Explanation:
The Hardy-Weinberg equilibrium states that the amount of genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
The Hardy-Weinberg equilibrium is expressed quantitatively using a mathematical equation known as the Hardy-Weinberg equation. the equation is given below:
p² + 2pq + q² = 1
also, p + q = 1
Given a pair of alleles, S and s with A dominant and a recessive
where p is the frequency of the dominant allele in the population,
q is the frequency of the recessive allele in the population,
p² represents the frequency of the (SS) dominant genotype,
q² represents the frequency of the (ss) recessive genotype,
2pq represents the frequency of the heterozygous genotype
From the given question,
q² = 1/10000 = 0.0001
q = 0.01
from p + q = 1
p = 1 - 0.01 = 0.99
p² = 0.98
Therefore, 98% of the US population have no alleles for PKU
Answer: meristematic
Explanation:
Growth occurs throughout the plant's life, a process known as indeterminate growth. This indeterminate growth is possible because, unlike animals, plants have perpetually undifferentiated tissues called meristems. Read about plant meristems.
Answer:
4) It allows the exchange of nutrients between the embryo and the mother, while at the same time filtering out harmful material.
Explanation:
The placenta is an organ present in all mammals. She is confirmed between the 6th and 8th week of pregnancy and has as main function the exchange of substances between the mother and the fetus. Among these substances are nutrients, gases and even secretions. The placenta also has the function of fighting infections and promoting immunity to the fetus, in addition, it can act as the lung, the intestine and the liver, while the fetus does not develop its organs.
Answer:
False
Explanation:
When non-random mating is being carried out, percentage and frequency data are usually affected because non-random mating have the tendency of changing the gene frequencies in a population. These non-random mating usually occurs when individuals choose to mate with superior physical traits or as a result of physical accessibility. The phenotypic characteristics are also greatly influenced by the biotic and abiotic environment they dwell in or other physical characteristics.
