Heritability is a measure that is used to estimate the variation of phenotypic traits (observable traits) in a given population due to the variation or changes in the genetic make up (genotype) among certain individuals. some of these traits includes color blindness, tongue rolling and curly hair among others. However, some traits such as nearsightedness are caused or influenced by the changes in the environment and therefore Heritability is not a factor to consider when dealing with such traits.
Answer:
(A) Sex-linked dominant
(B) Sex-linked recessive
Explanation:
This type of representation is used in pedigrees that express the inheritance of sex-linked characters, that is, those that are inherited through one of the sex chromosomes, which are the X or Y chromosomes.
For this reason it is necessary to represent males and females differently in the scheme
Because an organism needs even more cells to help it function better and change as it grows (like metamorphosis and yes, puberty :p) and if the same amount of cells stay then the organism's cells will be functioning and working harder.....so cells divide so many different ones can continue to work on different parts of the organism as it grows and changes. Plus it'd be weird if we only had like 1 thousand cells in our body from mothers' pregnancy the size of hi-polymer erasers (the big ones)..........
The possible answers are:
A. Variation in length of the amino acid backbone
B. Each protein is encoded by a distinct gene
C. Variations in the type of peptide bond
D. Variations in the glycosidic linkage
E. Variation in tertiary structure
<span>F. Variations in which amino acids are used
The correct answers are A,E and F
There are only 20 amino acids that make all of the proteins in our bodies. However, there are options for protein variation are almost unlimited.
Firstly, you can vary the number of different amino acid that you use to make a protein.
Secondly, you can also vary the length of the amino acid chain.
And thirdly, when an amino acid chain is formed different parts of the chain interact with each other, bonding chemically, forming different 3-dimensional structures of the protein.
All of this contributes to the vast variation in proteins.</span>
