Let's use A as the dominant allele for green seed colour and a as the recessive allele for yellow seed colour.
If a yellow seeded plant is crossed with a heterozygote,
aa X Aa
the yellow seeded plant would only produce one type of gamete (a) while the heterozygote would produce two different types of gametes (A and a)
If we put this into a Punnett square, we will see that there two two possible genotypes for the offsprings. Either Aa or aa.
Since the allele for green seed is dominant, Aa will exhibit the green seed colour phenotype.
Hence, the chance of getting an offspring with green seed colour is 1/2, or 0.5
Answer:
By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. ... Unlike in mitosis, the daughter cells produced during meiosis are genetically diverse.
Explanation:
This explanation and his theory were not widely accepted. Prior to Wegener, however, many had noted that the shapes of the continents seem to fit together, suggesting some schism in the past.
<span>Continental drift was really not allowable as even an accepted theory until the 1950s. Most geologists accepted the theory as quite possible before 1970. Several factors point to the acceptance of the continental drift theory. </span>
<span>Fossil records from separate continents, particularly on the outskirts of continents show the same species. As well mineral specimens along the supposed break lines of the continents are nearly identical. Some identical species exist on certain continents, like an earthworm common to both Africa and South America suggesting the species could not have spontaneously arisen on both continents without some variations hope this helps</span>
Answer:
Answer is B
