The correct answer is A. Phenotypes
Explanation:
In genetics, the observable traits of an organism that includes behavior, physical traits, biochemical properties, etc. are known as phenotypes. These traits depend on both the genes of the organism (genotype) and the influence of the environment. Due to this, organisms of the same species with a similar genotype can display different phenotypes. This occurs in the case of Patrick and Michael as their observable traits or phenotype is different despite they are brothers. Thus, the observable characteristics are the phenotypes of an organism.
Answer:
examples of sustainability?
Explanation:
Sustainability focuses on meeting the needs of the present without compromising the ability of future generations to meet their needs. The concept of sustainability is composed of three pillars: economic, environmental, and social—also known informally as profits, planet, and people.
Answer:
a) 9%.
b) 16.8%.
Explanation:
a).
We are provided with the information that Two linked genes, A and B, are separated by 18 cM (centiMorgan). i.e the recombinant frequency is 18%
Also , the man's genotype is AB/ab... This only result to one explanation, that The man will definitely produce 18% of recombinant gametes which entails
9% Ab & 9% aB
i.e 0.09 Ab & 0.09 aB
On the other-hand, The mother ab/ab have tendency to produce just one single type of gamete which is ab
∴
The probability that their first child will be Ab/ab will be
Pr ( Ab/ab) = (0.09) x (1)
= 0.09
= 9%.
b).
If the father produces 18% of recombinant gametes which entails
9% Ab & 9% aB , this typically implies that the number of the non-recombinant gametes will be;
100%-18% = 82% ( non-recombinant gametes)
i.e genotype AB/ab = 82%
AB =41%; ab = 41%
AB = 0.41 ; ab = 0.41
Now, the probability that their first two children will both be ab/ab:
Using Multiplication Rule to calculate the probability that their first two children (ab/ab); we have:
(0.41)(1) ×(0.41)(1)
= 0.1681
= 16.8%.
Gynmosperms are a group of seed producing plants, where the seed are grown on either the leaves (such as a ginko), or scales (such as a pinecone), and gametophytes are found in the same place as seeds, just in a different phase (2 ametes come together to make a seed)
