Given the parents AABBCc × AabbCc, assume simple dominance for each trait and independent assortment. What proportion of the pro
Anit [1.1K]

Answer:

3/4

Explanation:

If we assume simple dominance and independent assortment for each trait, we can use Mendel's Law of Segregation to predict the phenotypic proportions in the offspring of the parental cross AABBCc x AabbCc.

<h3><u>Gene A</u></h3>

AA x Aa

  • F1 genotypes: 1/2 AA, 1/2 Aa
  • F1 phenotypes: all A
<h3 /><h3><u>Gene B</u></h3>

BB x bb

  • F1 genotypes: 1 Bb
  • F1 phenotypes: all B
<h3 /><h3><u>Gene C</u></h3>

Cc x Cc

  • F1 genotypes:  1/4 CC, 2/4 Cc, 1/4 cc
  • F1 phenotypes: 3/4 C, 1/4 cc

We want to know the proportion of progeny with all dominant phenotype (A_B_C_). Since the genes are independent, we can multiply the probabilities of each gene to obtain the overall probability of having a ABC progeny:

<h3>1 A_ x 1 B_ x 3/4 C_ = 3/4 A_B_C_</h3>

valentina_108 [34]

Answer:

Resistance bacteria survive in greater numbers and pass the trait to their offspring

Explanation:

Antibiotics are chemicals which are used in the treatment of bacterial infections. The bacteria sometimes have some form of immunity or resistance to a particular antibiotic due to a host of underlying factors.

Once resistance appears in a bacterial population, it spreads rapidly. The trait of immunity or resistance to such antibiotic is then passed as a trait from one generation to another.

olga2289 [7]

New data about evolutionary relationship between organisms

Explanation:

New data about the evolutionary relationship between organisms most likely dictated that the domain level is adopted.

  • Evolutionary trends and morphological relationship between organisms became very important in the classification system.

Organisms are classified into the domain levels as:

  1. Archaea,
  2. Bacteria,
  3. Eukarya

This classification is based on the sequences of nucleotides in the cell.
