Fruit production in anthophytes develops from: a. a female reproductive structure b. a male reproductive structure c. both male
Fed [463]

Answer:

a. a female reproductive structure

Explanation:

Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.

Basically, there are two (2) methods of reproduction and these are;

I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.

II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.

Antophyte is the division name for flowering plants and they are considered to be the most successful of all the other division of plants in terms of reproduction.

Division Antophyta are classified into two (2) main categories and these includes;

I. Monocot: this group of flowering plants have a single cotyledon. Some examples of monocots are lilies, corns, grasses etc.

II. Dicot: this group of flowering plants have two cotyledon. Some examples of dicots are beans, peas, peanuts, etc.

Basically, fruit production in anthophytes develops from female reproductive structure known as the ovary. Once the ovary is fertilized by a sperm, they ripen into a fruit.

Why is insertion/deletion of three bases less deleterious than insertion/deletion of one or two bases.
Ede4ka [16]

Answer:

Explanation:

Insertion/deletion of 3 base which is a condon will be less fathal because only one amino acid will be missing from the protein of which the gene codes for.

If one codon is deleted it will still be the same but might cause a disease for example in cystic fibrosis one amino acid, 508th Phenly alanine is missing in the CFTR protein. They severity of diseases caused by Insertion or deletion is increased as the number of condon are more.

However, if only one or two is deleted/inserted then all the codons will shift causing them to be in different groups which may form a totally different amino acids as seen in frameshift mutation. This is more dangerous.
