Examine the genotype for an individual who is AaBbCcDc. Predict the outcomes of meiosis and the potential gamete combinations th

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.

What scientist is credited with proving that genes are located on chromosomes?

Natasha_Volkova [10]

There are many answers to this but I can narrow it down to two.
Wilhelm Roux was the one who officially speculated that the chromosomes was the carriers of inheritance.
BUT proving it is another story
Thomas Hunt Morgan showed that genes reside in specific chromosomes. He was able to map the fruit fly's chromosomal map.

Explain one adaptation that helps grasses succeed in grasslands

ehidna [41]

Answer:

Basal meristems

Explanation:

Meristems are the portion of plants able to generate any kind of new tissues. Therefore, the way plants keep their meristems protected is related to climate adaptation.

Grasslands tend to be arid ecosystems, so grasses have developed basal meristems, meaning they spend the dry season very close or under soil, where water evaporates slowlier than above surface, until wet season allows meristems to generate new stems and leaves.

This disposition is also useful in cases of fire and grazing, which are also frecuent in grasslands.
