Mendel carried out his research on garden peas. You should remember that he used seven pairs of traits. Modern geneticists have

Goshia [24]

Answer:

A. the two genes on chromosome 1 are more than 50 mu apart.

Explanation:

Two or more genes present on the same chromosomes are the linked genes. Linked genes do not assort independently and do not exhibit crossing over. Therefore, the linkage of genes results in deviations from Mendel's law of independent assortment. However, if the linked genes are present far from each other on the same chromosome, they may exhibit crossing over.

The greater the distance between the linked genes, the higher are the chances of crossing over. Crossing over of linked genes would result in some of the progeny to have the new gene combinations as it occurs during an independent assortment of two genes. Therefore, Mendel observed an independent assortment of two genes present together on chromosome 1 since they were present far apart from each other (more than 50 mu apart).

How do the simplest bacteria relate to the most complex animal?

SVEN [57.7K]

Answer:

Explanation:

As you probably already know, all of the cells in your body started from a single cell. That single cell then divided many, many times to turn into the 50 trillion or so cells that make up you. Almost all of the cells in your body share the same DNA as was found in that first cell

The components that make up the genetic code are common to all organisms! Same NUCLEOTIDES, same BACKBONE same BASE-PAIRS, same HYDROGEN BONDS! The instructions for making proteins (and traits) are in the sequence of nucleotides! These are the GENES that hold our similarities or differences

Determine the median value for foot width for males and for females. Describe in complete sentences the method you used to deter

Ipatiy [6.2K]

Answer:

This question is incomplete because of the absence of the data referred to in the question

Explanation:

This question is incomplete but the data referred to in the question is attached below

In order to determine the median value of any set of data, the data is first of all rearranged chronologically (ascending) and then the middle value is picked if the number of data is odd but if the number of data is even, the two middle values are added together and then divided by two to get the median.

From the data provided, the values (which are 10 in number) can be arranged as shown below (with the median values in bold)

Females: 5, 7, 7, 7.5, 7.5, 7.8, 7.8, 8, 8, 17

Males: 4.5, 7.5, 9, 9, 9.2, 9.3, 10, 10, 10.5, 13

Since the number of data is even, the two middle numbers (in bold) shall be added together and then divided to get the median as shown below

The median value for the females foot width is = 7.5 + 7.8/2 = 7.65 cm

The median value for the male foot width is = 9.2 + 9.3/2 = 9.25 cm
