Snap dragon flower color displays incomplete dominance. Which is the likely phenotypic ratio of the f2 progeny resulting from a

monohybrid cross of true-breeding parents with white and red flowers?.
Biology

Yanka [14]1 year ago

The correct answer is 1 red : 2 pink : 1 white

A monohybrid cross is made up of two organisms that have distinct variants at the same genetic locus. In a monohybrid cross, the character(s) under investigation are controlled by two or more mutations at a single gene locus. Each parent is selected to be homozygous or true breeding for a particular characteristic in order to perform such a cross (locus). When a cross meets the requirements to be classified as a monohybrid cross, it is typically identified by a distinctive distribution of second-generation (F2) offspring, also known as the monohybrid ratio. A monohybrid cross is a cross between two homozygous individuals, which produces the opposite phenotype for a particular genetic characteristic.

What are some disadvantages of fossil fuels?
Fed [463]

Answer:

B. Fossil fuels are nonrenewable and may cause pollution.

Explanation:

Fossil fuels are nonrenewable, meaning that they cannot be replenished sustainably. So, eventually, we will run out of them because they cannot be renewed.

Another disadvantage of fossil fuels is that they cause pollution. For example, the gasoline that is used by cars creates significant amounts of pollution every year.

Pollution is created by cars, factories, homes, and everything else that uses fossil fuels.

So, the correct answer is B, fossil fuels are nonrenewable and may cause pollution

Que sucedería con la especie humana si debido a una futura mutación genética sus células no pudieran realizar los procesos de mi
MaRussiya [10]

Answer:

la vida no podría continuar sin los procesos de división celular  

Explanation:

La mitosis es el proceso de división celular mediante el cual se producen dos células idénticas a partir de una sola célula. Durante la mitosis la célula crece y duplica la cantidad de ADN, con lo cual exactamente el mismo contenido de información genética es trasmitido a las sucesivas células que el proceso de mitosis va a dar origen. Por otra parte, la meiosis es un proceso celular en el cual se producen dos divisiones nucleares y citoplasmáticas (meiosis I y meiosis II) las cuales son precedidas por una fase de replicación del ADN. En la especie humana, la mitosis da lugar a células diploides (2n) con dos set completos de cromosomas homólogos, mientras que la meiosis da lugar a cuatro células haploides (n) llamadas gametos (el gameto masculino es el espermatozoide y el gameto femenino es el óvulo) las cuales contienen la mitad del número cromosómico al de la célula de origen. En organismos eucariotas pluricelulares tales como la especie humana, la función de la mitosis es producir más células somáticas (soma: cuerpo) con idéntico material genético, mientras que la función de la meiosis es producir células aptas para el proceso de reproducción, es decir, células con la mitad del material genético que se fusionarán para generar una célula diploide o zigoto a partir del cual y mediante sucesivas mitosis se desarrollará un organismo adulto.

Humans are diploid organisms, and their gametes contain 23 chromosomes. Fill in the blank in each sentence using the terms. Each
USPshnik [31]

Answer:

2n, n, diploid

Explanation:

<em>When the somatic cells of human are in interphase, the ploidy level is denoted as </em><em>2n (diploid)</em><em>. The ploidy level of the human's gametes is denoted as </em><em>n (haploid)</em><em>. The 2n number of a human is </em><em>diploid</em><em>.</em>

Somatic cells are also known as vegetative cells and all somatic cells of humans have diploid number of chromosomes. At interphase, the number of chromosome remains diploid (2n) but the amount to DNA is doubled at the synthesis phase of the interphase.

Human gametes are formed through meiosis - the division of sex cells in the human body. Meiosis results in the halving of number of chromosomes of cells. Hence, all human gametes contain half the number (n = 23) of chromosome of vegetative cells.

Humans are diploid organisms with diploid (2n = 46) number of chromosomes in their vegetative cells.
