Answer:

b. 2N meiosis 1N fertilization 2N

Explanation:

In eukaryotic organisms, gamete mother cells are diploid (2N) and have two complete sets of chromosomes. Meiosis in male and female gamete mother cells form haploid male and female gametes (N) respectively. This occurs since meiosis reduces the number of the chromosome to half in the daughter cells. The fusion of haploid male and female gametes during fertilization restores the diploid chromosome number of the species and forms diploid zygote (2N). Repeated mitotic divisions in the diploid zygote form the diploid organism.

Q:- Wing coloration in the magpie moth, a species
Fudgin [204]

Answer:

a) All males will have dark wings, all females will have light wings. See attachment

b) Males - 50:50 dark:light, females, 100% dark wings

Explanation:

The ZW sex determination system is different from the XY sex determination system. Females are ZW, whereas males are ZZ (in contrast to XY system where females have two of the same chromosome [XX] and males have two different ones [XY]).

a) The potential genotypes of the F1 are shown in attachment. This shows that all males will have dark wings (Ll) (all heterozygous) and all females will have light wings (l) (all will inherit l allele from father)

b) The potential genotypes of the F2 are shown in attachment. This shows that 50% of the males will have light wings (Ll), and 50% will have dark wings (ll). All of the females will have dark wings (L).

ryzh [129]
<h2>Answer is option "A"</h2>

Explanation:

  • The concept of actor-observer bias states that the causes of behaviors and events in our lives are motivated by attribution. Attribution is an inference that we make about our behaviors and the behaviors of others. The attributions we make depend directly on whether we are the actor or the observer.
  • The actor-observer difference inclination will be progressively articulated in circumstances where the results are negative. For instance, in a circumstance where an individual encounters something negative, the individual will regularly accuse the circumstance or conditions. When something antagonistic happens to someone else, individuals will frequently censure the person for their own decisions, practices, and activities.
  • Hence, the right answer is option A "actor-observer perspective".
