Answer:

You didn't include the following

however 2 heterozygotes

build a punnett square which is a just a box with the alleles contributing from each parent one on the top and one on the side

       A      a

A    AA     Aa

a      Aa   aa

That is what would happen so 25% chance of AA and 25% of aa and 50% chance of a heterozygote

Brainly won't allow the h o m o zygote to be included as an answer

Each individual inherits 23 chromosomes from their mother and 23 chromosomes from their father. In addition, epigenetic effects
vodomira [7]

Answer: Phenotype

Explanation:

The phenotype is the set of physical characteristics of an individual, that make it different from other individuals and are evident to the eye.

While the genes inherited from the parents determine the genotype of the individual, that's not enough to fully determine how it will look when it develops, as the ambient where it will grow takes a great part of it. Those factors are called epigenetics.

How an individual will look, its phenotype, is a result of its genes and the epigenetic factors.

Horses are much larger today than their two-foot tall ancestor, mesohippus. Geologists believe the change in size was the result
Darina [25.2K]
The answer is: <span>larger horses have longer legs.

</span>The ancestors of horses lived in the forest, where they could hide from the predators. But, with the first steppes, they could be spotted by the predators. Horses had to adapt in order to survive. Thus, their legs became longer through time so horses could run faster to escape predators.<span>

What three processes lead to variation among offspring that have the same two parents?
beks73 [17]

Explanation:

Genetic variation in offspring during sexual reproduction is caused by

  • crossing over
  • independent assortment
  • randomized fertilization

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.

  • crossing over:  the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.
  • independent assortment in metaphase I of meiosis: chromosomes align independently and genes segregate independently into new combinations ...in humans 2n, n = 23, 8 million combinations of chromosomes possible
  • randomized fertilization: sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes

How would you know if your results from experiment 2 show that the traits were inherited through mendelian genetics?
Karolina [17]
Genes they assort independently if they follow the 9: 3: 3: 1 rule resulting from a dihybrid cross.
It shows that the genes are not on the same chromosome and they are not included.
