1. You are studying a trait in corn that you believe exhibits Mendelian inheritance. You count phenotypes and find that there ar

e 375 of one phenotype and 125 of the other phenotype. When you perform a chi-square test, the chi-square value is zero. Your conclusion based on this test is
this trait is inherited in a Mendelilan fashion

none of the answers is correct

this trait exhibits codominance

this trait is not inherited in a Mendelian fashion

Answer:

This trait is inherited in a Mendelian fashion.

Explanation:

Chi-square test is used to test the relationship b/w variables, on performing the chi-square test on traits of corn, value that we obtained was zero, it means that there is no relationship b/w two traits. So, the trait has been inherited independently in Mendelian fashion.

Answer:

this trait is inherited in a Mendelian fashion

Explanation:

The chi-square test aims to verify whether the observed absolute frequency of a variable is significantly different from the expected absolute frequency distribution. Applies when one wants to study the dependency between two variables, through a double entry table or also known as a contingency table.

When chi square is calculated, the values of a table with constant numbers (called tabulated X) are compared with the result found in the chi square calculation. If the chi-squared value is zero, then there are no significant differences between the hypotheses. In the case of the above question, this would mean that the characteristic, studied in the above question, is inherited from Mendelian ways.

Reptiles are better suited to dry land than their amphibian ancestors because
Vaselesa [24]

Answer:

<u><em>All of the above.</em></u>

Explanation:

1. Their watertight skin minimizes moistures loss: <em>Reptiles have a reputation that they are “slimy” when we touch and hold them; however, they have dry skin, which has even fewer glands than mammals or amphibians. The main special feature of their skin is that the epidermis is heavily keratinized with a layer, which also prevents water loss.</em>

2. Amphibians must lay eggs in water or in moist soil to reduce moisture loss: <em>Because amphibian eggs don't have an amnion, the eggs would dry out if they were laid on the land, so amphibians lay their eggs in water.</em>

3. Reptile egg shells are harder than amphibians' eggs: <em>Reptile eggs are coated with a leathery or brittle coating, and the animals that hatch from them are miniature versions of the full-sized animal parent. In contrast, amphibian eggs are transparent and jelly-like. The animals that hatch from them still must go through metamorphosis.</em>

<u><em>Hope this helps you have a better understanding:) !!</em></u>
