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.
Answer:
Old Fishing Gear
Explanation:
The patch, in fact, is made up mostly of abandoned fishing gear. According to the study, fishing nets alone make up 46 percent of the 79,000 tons of garbage.
Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells.
