Answer:
Blending inheritance leads to the averaging out of every characteristic, which as the engineer Fleming Jenkin pointed out, would make natural selection impossible if blending were the mechanism of inheritance.
Explanation:
Hello!
Yellow = Y
Green = y
Based on the fact that 25% of the offspring inherited two recessive alleles (we know this because in order for a recessive allele to be expressed, it must be homozygous),<u><em> the parent peas had to both be heterozygous. </em></u>
Yy * Yy will always result in:
1/4 = yy
2/4 = Yy
1/4 = YY
I hope I helped!
The Gram-positive bacteria have a thicker cell wall than the Gram-negative bacteria.
When a single copy of a disease allele doesn't result in a disease but instead is good for the person or organism that carries it, we say that allele has a heterozygote advantage. In other words this occurs when heterozyhotes have increased fitness over both homozygotes. A good example is sickcle cell trait, which protects against malaria in heterozygotes, but causes a deadly disease in homozygotes.
The conclusion that can be drawn from the last statement is that ALL THE ANIMALS LISTED ABOVE ARE HYBRID ANIMALS.
Hybrid animals are those animals that are produce from the interbreeding of two animals that are of different species but which come from the same genus. Hybrid animals can not produce fertile offspring because they do not possess viable sex cells, that is, they do not have the capacity to reproduce sperms or eggs.
