Answer:
a. Multiple gene duplication events have led to the production of a paralogous multigene family.
Explanation:
A globin gene family consists of several clusters of related genes formed by duplication of an ancestral gene. The different variants of venom proteins coded by closely related genes can reply this ancestral gene, forming this way a globin gene family in Cone snails.
The attached ribosomes make protein

The correct answer is (A) Chromosomes.
The color of the horse coat is determined by chromosomes. The genes present on the chromosomes is responsible for the coat color of horse. The dominant coat color of the horse is transferred to the horse from its parents. This is inherited pattern and the coat color can be black, white, brown, etc.
The inversion would suppress recombination.
In Drosophila, the mutations which are recessive are lethal or recessive sterile. Balancer chromosomes are used to hold the deleterious mutations in stable shares as well as to save you recombination with the aid of suppressing.
Chromosomal inversions prevent the recuperation of recombinant chromosomes in ways.
- the crossovers do now not shape within the location of inversion breakpoints, due to the fact synapsis is inhibited.
- unmarried crossovers' inner inversions result in aneuploid gametes that cannot give upward push to normal progeny.
Drosophila is a genus of flies, belonging to the own family Drosophilidae, whose participants are often referred to as "small fruit flies" or (much less regularly) pomace flies, vinegar flies, or wine flies, a connection with the feature of many species to linger around overripe or rotting fruit.
