Pink eye is a recessive trait found in deer mice. In a cross between two individuals, both of whom are heterozygous for the pink
gladu [14]

Answer:

See the answer below

Explanation:

<em>If pink eye is recessive, it means that the normal eye is the dominant trait. According to Mendelian law, the ratio of normal to pink eye in a cross involving two heterozygous mice should be 3:1</em>.

Chi-square = \frac{(O - E)^2}{E} where O = observed frequency and E = expected frequency.

Phenotype      Observed            Expected          Chi-square

Normal                 18                3/4 x 20 = 15          \frac{(18 - 15)^2}{15} = 0.6

Pink                       2                  1/4 x 20 = 5           \frac{(2 - 5)^2}{5} = 1.8

Total Chi-square = 0.6 + 1.8 = 2.4

Degree of freedom = 2 - 1 = 1

Critical Chi-square value at 95% = 3.841

<em>The critical Chi-square value is more than the calculated value. </em><u><em>Hence, the observed number of offspring fits the expected number of offspring.</em></u>

Hay más agua salada o más agua dulce
Pavel [41]
Más agua salada

Al analizar la superficie del planeta, sencillamente se puede estimar que un 71 % está cubierto de agua, y el restante 29 % es masa continental. Ahora bien, la superficie no equivale a la masa, por lo tanto no podemos afirmar que la Tierra sea un 71 % de agua y el resto de tierra. Debemos ser un poco más específicos.
