Answer:
A) Traits can be dominant or recessive, and the recessive traits were "hidden" by the dominant ones in the F1.
Explanation:
Mendel discovered the fundamental theory of heredity: that inheritance involves the passing of genes (he called it discrete units of inheritance), from parents to offspring. Those genes are with two alleles in the genotype, one inherited from the father and other inherited from the mother.
When he cross-bred pure-bred parent (always produced offspring identical to the parent) plants dominant traits were always seen in the offspring, while recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. Mendel also noticed that in second-generation (F2) of the offspring 3:1 was ratio of dominant to recessive traits.
C. Glaciers cause erosion through the movement of large chunks of ice, which are deposited and form depressions

Explanation:
Answer:
Hemophilia is a sex-linked recessive disorder in which a person's blood do not clots and he can bleed to death even after minor injuries because blood will keep running due to a small cut.
It is a recessive trait which means that even if one normal gene is present along with Hemophiliac gene, the person will not have the disease and he will be the carrier.
Question: What will be their children’s possible phenotypes?
If a woman who is a carrier for hemophilia marries a hemophiliac man, their genotypes can be denotes as :
Here H, indicate normal gene and small h indicate defected (hemophilia) gene.
Parents: XHXh X XhY
Offspring: XHXh : XHY: XhXh: XhY
Phenotype of offspring:
XHXh: The child will be daughter and normal (25 % chances)
XHY: The child will be son and normal (25 % chances)
XhXh: The child will be girl and Hemophiliac (25 % chances)
XhY: The child will be son and Hemophiliac (25 % chances)
Hope it helps!
