Answer:

But hinnies and mules can't have babies of their own. They are sterile because they can't make sperm or eggs. They have trouble making sperm or eggs because their chromosomes don't match up well. ... A mule gets 32 horse chromosomes from mom and 31 donkey chromosomes from dad for a total of 63 chromosomes

The forked line and probability methods make use of what probability rule?

larisa [96]

Answer:

product rule

Explanation:

In Statistics, the product rule, also called the "Leibniz law", is a rule that allows the differentiation of products from differentiable functions. This rule says that the derivative of a two-function product is the first function times the derivative of the second function plus the second function times the derivative of the first function. This rule is often used in forked line and probability methods.

Explain Mendel's law of independent assortment and how the 9:3:3:1 phenotypic ratio among the F2 of a dihybrid cross provides ev

GrogVix [38]

Answer:

Explanation:

Mendel's law of independent assortment state that two different genes assort independently in gamete formation.

To reach this conclusion, one has to do a dihybrid cross. This means that two genes responsible for different traits need to be analyzed at the same time.

1) Starting with a parental generation of a cross between two pure lines (homozygous for both genes) with different traits, a plant with yellow and round seeds (YYRR) and another with green and wrinkled seeds (yyrr). The F1 will be phenotypically homogeneous (yellow and round), and genotypically heterozygous (YyRr).

2) If the individuals from the F1 are crossed with one another, we have to do a Punnett Square to determine the phenotypic ratio of the F2.

If the genes assort independently, the F1 individuals will produce their different gametes with the same probability. Each possible gamete will appear in a 1/4 proportion: YR, Yr, yR, yr.
The 9:3:3:1 ratio is a result of analyzing the possible phenotypes that result from the dihybrid cross.

See the attached image for an illustration of the crosses in each generation and the Punnett Square.
