Examples of chemical mutagens would be nicotine and other compounds in cigarette smoke that cause mutations involved in lung cancer.
Answer:
These cells are Eukaryotic and are autotrophic
Explanation:
These are the cells of onion. An oinion is a plant and because it is a plant it is autotrophic meaning they make their own food. Also plants are eukaryotic which means they have a nucleus.
Answer:
a dominant mutation
Explanation:
A monohybrid testcross is a cross-breeding experiment used to determine if an individual exhibiting a dominant phenotype is homo-zygous dominant or heterozygous for a particular phenotypic trait (in this case, wing length). In a monohybrid testcross, a 1:1 phenotypic ratio shows that the dominant parental phenotype was a heterozygote for a single gene that has complete dominance. Moreover, a 3:1 ratio in the F2 is expected of a cross between heterozygous F1 individuals, which means that 75% of individuals with short wings have the dominant allele that masks the expression of the long-wing trait (i.e. the recessive allele).
