Answer/explanation:
3.
A) A dominant allele is the allele that is more prominent and over rules the weaker/recessive allele.
B) a genotype is the genetic make up that is in a living organism. A phenotype is the physical traits that one has (ex. blue eyes, curly hair)
C) Heterozygous, hetero meaning different, means that it is a mix of two different alleles (ex. Bb). Homozygous means two of the same (ex. BB or bb).
4.
A) The genotype, the actual make up ends up being a mix of both parents (heterozygous). It is, Hh.
B) Usually in biology the capital letter is the more dominant allele/gene, therefore the phenotype (physical feature) should be the child having a widow's peak.
explanation: Since the dominant gene is the widow's peak then that will be the gene that shows up in the child's phenotype.
