Answer:
yes a child inherits 50% of their DNA from mom and 50% from dad
Explanation:
Males are heterogametic as they produce two types of gametes one carrying an X and the other carrying Y chromosome. Females are homogametic because they produce one type of gamete carrying the X chromosomes. The chromosomes are inherited equally in the mendelian fashion. Genes on the chromosomes are therefore inherited equally with 50% coming from the mother and 50% coming from the father.
Bacteria are the simplest single cells that carry out all basic life activities.
