The venom of a black widow spider is toxic to the nervous system.
Answer:
<em>A mutation in his offspring</em>
Explanation:
A mutation can be described as any change which occurs in the DNA of an organism. Mutations can be either heritable or non-heritable
If a mutation occurs in the gamete cells of a male, the mutation will be heritable and will occur in his offsprings.
Other options, like option D, is not correct because a mutation in the gamete cells will not cause a mutation in the somatic cells. Gamete cells are the sex cells and hence mutation will arise in the sex cells.
Answer:
The peas with the purple flowers were dominant and the peas with the white flowers were recessive.
Explanation:
In Gregor Mendel's study, he studied pea plants with purple flowers and white flowers. The purple flowers were dominant, and whenever the allele for a purple flower was present is was visible on the plant. The white flowers were recessive because if an allele for a purple flower was present, then the flower was purple. The flowers were only white if both alleles were for white flowers.
Your answer would be, HOMEOTIC GENES, is the master control gene, that regulate other genes.
Hope that helps!!!!
