Answer:
Sex Cell
Explanation:
A cell whose nucleus unites with that of a cell of the opposite sex to form a new organism. A reproductive cell contains only a single set of chromosomes. Animal egg and sperm cells, the nuclei in grains of pollen, and egg cells in plant ovules are all reproductive cells. Also called gamete, sex cell.
Answer:
The question is incomplete, it lacks the main questions, those questions are:
a. What is the genotype for black chickens?
b. What is the genotype for white chickens?
c. What is the genotype for erminette chickens?
Explanation:
This question involves a gene coding for feather colour in some birds, in which the black allele (B) and white allele (W) is involved. According to the question, the gene coding for feather colour exhibits co-dominance i.e. both the black (B) and white (W) allele are expressed in a heterozygous state (BW) to form an erminette phenotype.
Hence, if the neither alleles is dominant or recessive over the other. The black phenotype will only be expressed when the genotype is BB.
The white phenotype will only be expressed when the genotype is WW
The combination of both alleles which results in the simultaneous expression of both in the erminette phenotype, will be BW genotype.
The only living thing that makes its own food is the plant. So the first step in a food chain is always a plant that makes its own food by sun. :)))
