Answer:

X=4, x=-6

Step-by-step explanation:

subtract the 24 over. Then factor, what multiplies to negative 24 and adds to 2, which is -4 and 6. Your factors are (x-4)(x+6). set each of those to zero. x=4 and x=-6

For tall heterozygotes with antennae, the offspring are:

Misha Larkins [42]

Recombinant frequency between T and A is 12%

Explanation:

Two characters are considered - height and antennae

Traits of height - Tall and Dwarf

Traits of antennae - Antennae and No antennae

Given:

Tall-antennae (46) and dwarf-no antennae (42) are the wild type.

Dwarf- antennae (7) and tall- no antennae (5) are the recombinants.

Total possibilities = 100

Recombinant frequency = $\frac{7}{100} + \frac{5}{100}$

Recombinant frequency = $\frac{12}{100}$

Recombinant frequency in percentage = $\frac{12}{100} X 100 = 12$ %

Therefore, recombinant frequency between T and A is 12%
