Answer:
A. Incomplete dominance.
Explanation:
Incomplete dominance is the ability of two alleles to produce a heterozygous phenotype different from the two homozygous phenotypes.
Example is when a pure stock of red flowered (RR) four o'clock plant is been crossed with a white flowered(rr) one, the offspring are all pink flowered(Rr), showing a blending of flower colour character. Self pollination of the pink flowered F1 individual produce a mixture of F2 individual bearing red, pink and white flowers in the ratio of 1:2:1. This reappearance of the red flowered and white flowered forms in the F2 generation shows that alleles R and r have remained unaltered in the F1 generation.
The correct answer of the given question above would be option D. The option that did not occur during the Cenozoic era is the formation of the ozone layer. The ozone layer has long been there before any era since it is part of the earth's atmosphere. Hope this answer helps.
The correct answer is c i believe
The correct answer is: C) the random and independent way in which each pair of homologous chromosomes lines upat the metaphase plate during meiosis I
Independent assortment is the second Mendel’s law which states that the alleles of two/more different genes are sorted into gametes independently.
When homologous pairs line up during the metaphase at meiosis I they do that random. This means that formed gametes will get different combinations of "mom" and "dad" homologues and consequently, different alleles on those homologues.
