aBCd
aBcD
aBcd
abCD
abCd
abcD
abcd

Explanation:

Gamete formation involves the random and independent segregation of alleles. During anaphase 1 (meiosis), occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair.

The number of gametes with different combinations is 2ⁿ, where

n = number of homologous pairs.

In the exposed example there are 4 pairs of chromosomes, so

the number of possible combinations of chromosomes = 2ⁿ = 2⁴ = 16

Individual: AaBbCcDdEe

You can make use of the fork line method to easily figure out the possible gametes.

In bacterial and archaeal cells, the electron transport chain is located in the _________ whereas in eukaryotic cells, the elect

ANEK [815]

Answer:

Cell membrane of prokaryotes and Inner mitochondria of eukaryotes

Explanation:

Electron transport chain is a part of oxidative phosphorylation which is the third step of aerobic cellular respiration in living organisms. The ETC is a complex of proteins and mobile electron carriers. It occurs when electron is being transferred from one electron carrier to another, starting from NADH and FADH2. A proton pump which is used to synthesize ATP is generated at the end.

This ETC process occurs in the cell membrane of prokaryotic cells due to the fact that they lack a membrane-bound Mitochondrion. ETC occurs in the inner membrane of the mitochondria called CRISTAE in eukaryotic cells.
