Answer» racteristics or traits of parents are transmitted to their progeny (OFFSPRINGS) through genes present on their CHROMOSOMES during the PROCESS of sexual reproduction. ... Thus, the male and female gamete carries one gene for each characteristic from the gene pairs of parents.Acquired traits are the changes caused in non-reproductive tissues by the environmental factors. For example, darkening of the skin due to prolonged sun exposure which does not have any survival advantage. It does not show any significance in evolution. Therefore, acquired traits are not INHERITED.MEN have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father. Mitochondrial chromosomes are inherited solely from the mother. Men inherit their mother's mitochondrial genes but do not pass them to their offspring. |
