Why don't populations of organisms that reproduce asexually have the same genetic variation as populations that reproduce sexual

ly?
Asexual reproduction uses mitosis but not meiosis.

Organisms reproducing asexually only undergo meiosis.

Gamete formation does not include crossing over events in meiosis.

Consistent arrangement of chromosomes in metaphase I reduces genetic variability.

A gene for corn has two alleles, one for yellow kernels and one for white kernels. Cross pollination of yellow corn and white co
Rina8888 [55]

The question is incomplete. The complete question is:

Question: A gene for corn has two alleles, one for yellow kernels and one for white kernels. Cross pollination of yellow corn and white corn results in ears of corn that have an approximately even mix of yellow and white kernels. Which term best describes the relationship between the two alleles?

a) Incomplete dominance

b) Genetic recombination

c) Chimerism

d) Codominance

Answer:

d) codominance

Explanation:

Codominance is a pattern of inheritance when none of the alleles of a gene is able to mask the expression of the other allele of the same gene. When the two alleles are present together in a heterozygous genotype, both are expressed and the phenotype of the heterozygote is different from both the pure breeding parents. In the given example, cross-pollination of yellow corn and white corn results in the ears of corn that have an approximately even mix of yellow and white kernels. This means that the heterozygote expresses both the allele for the corn color. Therefore, it represents codominance.

The pH of a solution containing 0.1 mM H+ is _______ ( 1mM = 10-3M)
Taya2010 [7]

Answer:

The pH of a solution containing 0.1 mM H+ is 4

Explanation:

The pH of any solution is given by the following mathematical equation -

pH = -log[H_{+}]\\----------- Equation (A)

Where,

H_{+} = the concentration of hydrogen ion in the solution.

Given

H_{+}

= 0.1mM\\=0.1 * 10^{-3}\\= 10^{-4}\\

Substituting the given value in equation (A) , we get -

pH = -log[10^{-4}]

= -(-4)\\= 4

Hence, The pH of a solution containing 0.1 mM H+ is 4

Mendel also wondered if the inheritance of one trait affected the inheritance
svet-max [94.6K]

Answer:

A. dihybrid crosses

Explanation:

A dihybrid cross can be defined as a mating experiment between two lines/varieties/organisms that differ in two phenotypic traits. By using pea plants, Mendel performed dihybrid crosses in order to analyze the mode of inheritance of both phenotypic traits at the same time. From these mating experiments, Mendel observed that the inheritance factors (nowadays called genes) sorted independently from one another in the next generation, which is called the principle/law of Independent Assortment.
