Answer:
1. Character
2. Trait
3. Monohybrid cross
4. Alleles
5. Dominant allele
6. Recessive allele
7. Phenotype
8. Genotype
Explanation:
1. Character is an inherited feature passed through genes that varies in individual e.g flower colour
2. A trait is the variant form of a character e.g red and blue flower colour are variant forms of the flower colour character.
3. Monohybrid cross is a cross between two parents differing in only one character.
4. Allele is an alternate form of a gene e.g A and a alleles for gene A
5. Dominant allele is one of the allelic pair that expresses itself by masking the expression of the other allele in a heterozygous state.
6. A recessive allele is the allele that is masked or not expressed in a gene. It is covered up by the presence of the dominant allele.
7. Phenotype is the physical and visible trait of an organism e.g Tallness, colour
8. Genotype is the genetic constituent of an organism e.g AA, Aa etc.
Nucleotides are the building blocks of DNA macromolecules
Answer AND Explanation:
The seminal vesicle produces an alkaline fluid which contains nutrients for the spermatozoa. Near this point is situated the prostate gland whose secretion is alkaline to neutralise the vaginal fluids. It also activates the sperms. The cowper's' gland secretes alkaline fluid that neutralises the acidity along the urethra. All the fluids combine with the spermatozoa from the vasa deferentia to form semen.
