TRUE. THE NUCLEAR FAMILY IS THE MOST COMMON FAMILY STRUCTURE IN ALL CULTURES AROUND THE WORLD.

It is the traditional family structure that consists of two parents and their children. In the US, it is said that 70% of children live in a nuclear family unit. 

Other family structures include:
1) single parent family
2) extended family
3) childless family
4) step family
5) grandparent family

How do the cells in meiosis differ from the cells in mitosis?
AfilCa [17]

Answer:

C. Cells in meiosis have unique genetic information

Explanation:

Meiosis is the cell division that forms four daughter cells from one parent cell. It includes two successive divisions called as meiosis I and meiosis II. Crossing over during prophase I of meiosis I imparts new gene combinations to the daughter cells of meiosis. Hence, daughter cells formed by the end of meiosis have some new gene combinations, that is, unique genetic information.

Why are baboons, sparrows, and human beings considered both primary and higher order consumers?
SIZIF [17.4K]
Baboons, sparrows, and human beings are considered both primary and higher order consumers because they all eat plants and meat.

A maize plant with genotype Aa Bb produces the following gametes 100 Ab 45 AB 106 aB 50 ab This tells us that the two genes are
bogdanovich [222]

Answer:

True

Explanation:

The linkage relation of two genes can be determined on the basis of calculating recombination frequency.

If the recombination frequency value is greater than 50% then the genes are not linked and if the value is less than 50% then the genes are linked.

In the given question, the  crossover gametes formed will be Ab = 100

and aB= 106.

Therefore,

\dfrac{recombinant\ progenies}{ Total\ progeny}\times 100\\\\\dfrac{100 +106}{100+106+45+50}\times 100\\\\=\dfrac{206}{301}\times 100\\\\= 68.43\%

Since the recombinant frequency value is larger than 50% therefore the genes do not show linkage.

Thus, True is the correct answer.
