Answer:
C. petals
Explanation:
A)fruits
B)sepals
C)petals
D)anthers
E)ovaries
<em>The part that will not be necessary in wind pollinated angiosperm is the petals .</em>
The petal is a part of flower that is usually colorful and primarily function by attaracting insect pollinators to the flower.
<u>Since wind pollinated angiosperms do not need to attract insect for pollination, they do not need the colorful petals. They rely on wind to carry their pollen from their anthers to their stigmas (pollination).</u>
Hence, the correct option is C.
Answer:
Law of Independent assortment
Explanation:
Gregor Mendel, who was regarded the father of Genetics, discovered principles that governs inheritance in his experiments. He discovered that the alleles of a gene will separate into gametes when he performed a crossed involving a single gene or character like height, pea color etc. He proposed his law of segregation based on this.
However, he considered two characters or genes in his cross, which he called a DIHYBRID cross. He discovered that the alleles of each different gene separates into gametes independently of one another i.e. without one gene influencing the other in each gamete. He called this principle his LAW OF INDEPENDENT ASSORTMENT.
He obtained a 9:3:3:1 phenotypic ratio for the F2 dihybrid offsprings which is only possible if each gamete equally likely contains two alleles of the two different genes in different combinations.
Answer:
A: A tool for showing possible alleles of offspring in a test cross
Explanation:
Punnet squares use the alleles of the parents to find possible alleles of their offspring.
