If flies that are heterozygous for all three traits are crossed, what proportion of the offspring would you expect to be heteroz

Archy [21]

Answer:

$\frac{1}{8}$

Explanation:

If flies that are heterozygous for all three traits are crossed; e.g HtHtHt crosses with HtHtHt. The proportion of the offspring that would be expected to be heterozygous for all three traits will be: 1/8 because 50% (0.5) of their offspring will be heterozygous for just one trait. Therefore for three traits; we have (0.5)³= 0.125

0.125 is equivalent to $\frac{1}{8}$

From the table, the area of the asterisk region illustrate the traits that are heterozygous in the offspring.

= $\frac{8}{64}$
