Answer:
A parent with one copy of a dominant allele and one recessive coded Ww for the widow's peak is called heterozygous for a trait and has a 50 percent chance of passing on the dominant allele to each of his or her offspring, regardless of the gene inherited from the other parent.

Answer: Louis Pasteur
Louis Pasteur in 1860s, proposed germ theory. The theory was based upon the fact that diseases are caused by the microorganisms. He was officially the first to publish his work.
Answer:
The genotypes of the two parents: normal head shape (HH) and Bart head shape (hh)
The genotypes in the F1 generation= Hh
The phenotypes present in the F1 generation= All normal head shape
Explanation:
Let's assume that the allele "H" is responsible for the normal head shape while the allele "h" gives Bart head shape. According to the given information, both the parents are homozygous. The genotype of the parent with normal head shape would be "HH" while that of the one with Bart head shape would be "hh". Since the normal head shape is dominant, all the F1 hybrid progeny would exhibit "normal head shape".
