Answer:
A gene map shows how the chromosomes of genes are arranged in a particular space. This allows the researcher to know how certain traits can be inherited based on the pattern they show.
Explanation:
Gene maps may be generated through: <em>physical mapping or genetic mapping. </em>Physical mapping uses the technique of molecular biology while genetic mapping utilizes genes.
This can also be used to identify disease genes, since these are caused by abnormalities in the human's genome. It allows analysis in order to identify or predict what causes mutation.
So, this explains the answer.
Detached ear lobe allele is dominant over attached ear lobe allele
<u>Explanation:</u>
Mendel is the one who found the reason why an offspring has characteristics of the parent. He found that some traits were exhibited in an individual while the others were not. So he named the expressive allele as dominant trait and the one which in not expressive as recessive trait.
He formulated a set of hypothesis and experimented it on the pea plant to form the “Law of Inheritance”. In humans the detached ear lobe, blood groups all are examples of the law of dominance. Hence Mendelian traits are the physical characters that are passed on from one generation to the other

Answer:
b. Highly repetitive sequences
Explanation:
As the name suggests, highly repetitive sequences are the sequence in the linear chain of DNA that are repeated many times in the whole genome. Though these sequences occur in abundance in the genome but it is interesting to note that these do not code for any protein. These sequences can be short as of 5-100 nucleotides and are repeated for thousands times in a single stretch of genome and include the satellite DNA. The longer sequences can be 150-300 nucleotides and include transposons and Alu sequences.
