Question

1. experiment: turn on show statistics and show as approximate %s. breed approximately 500 offspring. record the results in the table below. (hint: to obtain an f1 mouse, breed an ff mouse to an ff mouse. place two f1 offspring in the cages, click clear, and then drag the f1 mice into the parent boxes.)

parent 1 genotype	parent 2 genotype	% black offspring	% white offspring
f1	ff	50%	50%

1. draw conclusions: how well did the punnett squares predict the offspring percentages for each pair?

they were accurate

1. summarize: in your own words, describe what heredity is and how it works in mice.

think and discuss: do you think most traits are inherited the way mouse fur color is? why do you think so?

Explanation:

Heredity is the passing - on of traits from parents to offspring through genes. In mice, genes determine fur color. If a dominant allele (e.g., for black fur) is present, it may be expressed in the offspring. Punnett squares are used to predict the probability of different genotypes and phenotypes in offspring. Some traits are inherited in a simple Mendelian way like mouse fur color, but many traits are more complex, influenced by multiple genes and environmental factors.

Answer:

Heredity is the transmission of traits from parents to offspring via genes. In mice, genes control fur - color traits. Some traits follow simple inheritance patterns like mouse fur color, but most are more complex due to multiple genes and environmental influences.
