What was the purpose of Mendel's experiments with dihybrid crosses?

Biology

Answer:  The correct option is B. To determine if one trait could affect the inheritance of other trait.

The dihybrid cross is a cross between the two parents who have difference in two pairs of the alleles.

In the experiment of the dihybrid cross, during the first meiotic division the homologous pair of the chromosomes aligned randomly before getting separated from each other. The separation of the chromosomes leads to independent assortment. The four cells which are formed during the second meiotic division are developed into the haploid gametes.

The relationship data of the dominance for each trait between the alleles was available with Mendel. The purpose of the dihybrid cross was to determine the type of relationship that existed between the pair of alleles.

The result of the experiment of the dihybrid cross was the law of independent assortment according to which the formation of gametes the segregation of alleles of both the pairs of alleles are independent of each other.

If an adult dog has 78 chromosomes the number of chromosomes in a dogs sperm cell will be
Sergio039 [100]

39

Reproductive cells are haploid (have 1/2 the chromosomes), whereas somatic/body cells are diploid (have the full set of chromosomes)

This makes sense if you think about it. Using the example from the question, every dog has 78 chromosomes. This includes two of each (there are two chromosome 1's, two chromosome 2's, etc. This is visible in the karyotype attached). One set of these chromosomes were inherited from the mother, and one set from the father. Each parent contributed 39 chromosomes (one chromosome 1, one chromosome 2, etc.). If the dog in the question were to have 78 chromosomes in its sperm cells, it would contribute two sets to its offspring. When combined with the chromosomes in the egg cell, the offspring would end up with extra chromosomes. Therefore, both the sperm and the egg cells will have 39 chromosomes, one of each. When combined, they will produce offspring with 78 chromosomes, the proper number.

What are the advantages of live birth compared to ovulation?
olya-2409 [2.1K]

Answer

Just think critically about why (if you were an egg laying species), having a fetus/baby develop inside of you would be advantageous.

For one, eggs are much less protected from outside factors such as predators, temperature, etc than live birthed creatures. Live birth provides protection inside the mothers body from things such as heat, cold, moisture, predatory animals, etc. An egg laying animal must keep its eggs at a perfect temperature and check to make sure no other animal has eaten them.
