Answer:

Brown is the dominant gene and white is the recessive gene.

Explanation:

If brown were to be dominant then the mice would most likely all be brown unless the got both a white from mom and dad which is most likely due to brown being recessive the dad could be part white you just wouldn't see it. And since the mother is white all of the mice get a white gene from the mom and since the dad most likely has a white gene hidden inside of him only tow mice became fully white while the siblings were brown.

Hope this helps.

A dihybrid cross is performed between plants that differ in two Mendelian traits: Stem length (T or t) and flower coloration (R
Dahasolnce [82]

Answer:

A. 3/16

Explanation:

The four possible outcomes for Stem length are:

Tt, tT, TT and tt.

The dominant trait (tall stems) will manifest itself in 3 out of 4 outcomes, so its ratio is 3/4.

The four possible outcomes for flower coloration are:

Rr, rR, RR and rr.

The non-dominant trait (white flowers) will manifest itself in 1 out of 4 outcomes, so its ratio is 1/4.

Multiplying both ratios gives us the ratio of offspring that have tall stems and white flowers:

\frac{3}{4}*\frac{1}{4}=\frac{3}{16}

Therefore, the answer is A. 3/16

wariber [46]

The regression equation is:

y = 1.15 – 0.251 x₁ + 0.078 x₂ + 0.306 x₁x₂

<span> <span> <span> Where,
x₁ = -0.2508
x₂ = 0.0777
x₁x₂ = 0.3058

Inserting the values,
<span><span></span></span>y = 1.15 – {0.251 × (-0.2508)} + {0.078 ×(0.0777)} + {0.306 × (0.3058)}
</span></span></span>
y = 1.15 - (- 0.0629508) + 0.0060606 + 0.935748

y = 1.15 + 0.0629508 + 0.0060606 + 0.935748

y = 1.3125862

Answer:

x₁ and x₂ are main effects (a type of tuna and type of packing liquid) that contribute significant information for the prediction of <span>y.</span>
