a. genetic composition for a trait in a particular population.

b. phenotypic variation of a trait in a particular population.

c. variation in a phenotype caused by the environment.

d. proportion of genetic contribution to a trait in a particular population.- CORRECT

!!!!CAN YOU PLEASE EXPLAIN WHY THE OTHER ANSWERS ARE INCORRECT!!!!1

Expert Solution

1. Correct answer:- (e) two of the above
Explanation:-
(a) In human, sperm-derived paternal mitochondria enter the oocyte cytoplasm.
-After fertilization, mitochondrial DNA is never transmitted to the offspring. Hence interitance is not maternal.
(b) Mitochondrial DNA is a double helixed circular molecule.
(c) mitochondrial Functions ( oxidative phosphorylation) depend upon factors which are encoded both by the mitoochondrial DNA and nuclear genome.
(d) Mitochondrial chromosome is not inheritable so its diseases are not inherited,and have minor effect.

2. Correct answer:- (d) differential gene
expression
Explanation:-
(a) pleiotropy:-it is defined as a phenomenon in which one (usually mutant) allele influences two or more apparently unrelated phenotypic traits.
- shows how mutation in one gene leads to disease.
(b) heterogeneity:- state of being heterozygous, containing different allele in a single gene.

(c) Epistasis:- when two different genes which are not alleles, both affect the same character in such a way that the expression of one inhibit or suppresses the expression of the other gene, called epistasis.
(d) differential gene expression:- it shows that all cells in the body have the same genome, but express different parts on it (differential expression) depending on cell type and tissue.
- genomic imprinting based on it.

3. Correct answer:- (e) requires information from only one of her X chromosomes.
Explanation:-
(a) in oocyte only found during mitosis.

(b) female has development of gonads differently.
(C) fusion of mullerian
