Gray seed color in peas is dominant to white. Assume that Mendel conducted a series of experiments where plants with gray seeds
bazaltina [42]

Answer:

(a) Gg × Gg; (b) genotypic = 1:2:1, phenotypic = 3:1

Explanation:

a) A cross between two gray seeded plants produces progeny with gray and white seeds in 3:1 ratio (302:98=3:1). This means that the parent plants are heterozygous and each has at least one recessive allele. If the allele "G" is responsible for gray seed and the allele "g" imparts white color to the seeds, the genotype of the heterozygous parents would be "Gg".  

b) A cross between two heterozygous gray seeded parents would produce progeny in following ratio:

Genotype ratio= 1 GG: 2 Gg: 1 gg

Phenotype ratio= 3 Gray: 1 white

which is an example of biodiversity 900000 fires, deforestation, thousands of species carbon dioxide?
stira [4]

Answer:

Thousands of species is an example of biodiversity.

<u>Explanation: </u>

<em>Biodiversity is the short term for biological diversity which was coined by E.O. Wilson</em>. <em>Biodiversity refers to all the species of plants (flora) and animal Kingdom (fauna) present on the Earth.</em> It covers different types of ecosystems present in a well-defined area whether it be terrestrial or aquatic and the genetic variability within a species.

The variety of crops and livestock present on Earth have played a great role in human development. Without them, life would not be possible. That’s why it is our moral duty to conserve our biodiversity. If we preserve it for our future generations, we will survive.  If they are overused or misused, the entire food chain would perish.
