Answer:
how are genes expressed for a particular trait?
Genes are expressed in two ways which could be either genotype or phenotype
genotype reflects the dominancy or recessives of a particular trait over another while phenotype entails the physical expression of such trait which could be height, color of skin among others
e.g
If P is purple while p is white
PP x Pp= PP, Pp, PP. Pp these are the genotype produced from the crossing of two parents which results into 2 homozygous gene and 2 heterozygous gene without any recessive gene

Answer:
64.
Explanation:
It is 64 because there are 20 amino acids with four bases ( A,T,C and G).
and genetic code can be read in triplets and also the four bases can occupy the positions. Eachh amino acid can be coded by the triplet codons. A triplet codon shows three nucleotides of the mRNA template that can code for amino acid
Therefore the number of codons is 4×4×4= 64.
Answer:
A male and a female have sexual interactions. While this, the male releases sperm cells which go into the females egg cells. This then forms into a baby and slowly grows. Then about nine months later the baby comes out of the females vagina.
Homeostasis, Reproduction, and Metabolism are all the consequence of various organs imparting and arranging in a way that takes into consideration the detail of specific cells to do certain things. Since we have such a variety of organs to do diverse things, the cells can concentrate on doing one capacity rather than one cell doing the greater part of the capacities we can do today. We advanced from single cell creatures into what we are today through a large number of years of adjustment and the passing on of qualities that are the best fit for the earth. Creatures are the consequence of a huge number of years of cooperation from cells to make this extreme being that is us.
