Genetics Review Part 2 Quiz Wiz 1-10- ANSWERS

1. In white fish, light grey coloring of the scales can mask over the allele of dark grey scales. So when a white fish with light grey scales has offspring with dark grey scales, all the offspring have light grey scales. Which of Mendel’s Laws best explains this? The Rule/Law of Dominance- One trait can mask the expression of the other.

2. Many traits such as spots on body, length of fins, and color of skin can be observed on catfish. It is possible to see any combination of these traits in individual catfish. Which of Mendel’s Laws best explains this? The Law of Independent Assortment- if genes are located on separate chromosomes they are inherited independently.

3. In humans, hairline shape (smooth or widow’s peak) is coded for by a single pair of genes. A man with a widow’s peak has several children with a woman who also has a widow’s peak and some of the children have a smooth hairline. Which of Mendel’s Laws best explains this? The Law of Segregation- Only one allele/gene can be passed down from parent to offspring. Allowing traits that are not seen in parents to become visible in next generation of offspring.

4. Every pea plant has 2 genes for each of their traits 4. Every pea plant has 2 genes for each of their traits. One gene they received from the egg in the ovule/ovary, the other gene they received from sperm in the pollen. Which of Mendel’s Laws best explains this? The Rule/Law of Unit Factor- Each organism has two factors/genes for each trait. GENES ALWAYS COME IN PAIRS
