E)bacteria. 3) Which of the following is true according to Mendel's law of segregation? A)Each individual contains two alleles for each trait. B)Fertilization restores the presence of two alleles. C)Alleles separate from each other during gamete formation. D)Each gamete contains one copy of each allele. -E)All of the answer choices are true about Mendel's law of segregation. 4) An individual's physical characteristics, or microscopic and metabolic characteristics, are known as their -A)phenotype. B)genotype. C)alleles. D) traits. E)pedigree. 5) The genetic makeup of an individual is also known as their A)phenotype. B)loci. -C)genotype. D)factors. 6) If 7-tall and f-short in plants, the genotype of a short plant would be A)either IT or TT. B)either Tt or tt. C)only TT. Donly it. E)TT, TI, or tt.

(1) A) (2) B) (3) (E) (4) ^) (5) c) (6) D) - TT, Tt Tall, tt Short () B) Father Bb or bb Mother Bb Bb B. b Fertilization bb y - Father can be blue eyed or Brownd eyed But Mother is already given is a brown Eyeda It can not be 'BB' because child in blue eyed means 'bb which got one lb allele From mother.

Inclividuals with the edge of the 'T' allele the tongue have ability upward but to roll not with 't allele. - and 't allele is clominant. So, Individuals with TT or Tťť genotype have ability to roll the Edge . But not in individual with tt genotype, because both alleles are seccessive.
