Answer:
The correct answer is : 0.264
Explanation:
The total population of the Soay sheep is : 368 dark sheep + 132 light sheep
= 500 sheep.
Total dark coat sheep ( dark allele represented by D as it is dominant) = 368
Total light coat sheep ( light allele represented by d as it is recessive) = 132
As we know crossing is took place in between true breeding:
DD × dd
F1, Dd ( all are dark coat)
So, the genotype frequency of the homozygous recessive allele is
= 132/500 (by Hardy - Weinberg equation)
= 0.264
Thus, the correct answer is 0.264.
Answer:
Expression that compares the two quantities is "Ratio"
Explanation:
When the two quantities or the numbers are compared and can be measured can be written as the same unit. For example the ratio of 2 to 3 can also be written as 2:3 or may say . The relative magnitudes of the two quantities can be expressed as quotient. These two quotients can be compared by division. Ratio is the quantitative relation of two amounts which shows the number of the times any value contains or contained within the other.
Answer:
A. Both produce sex cells.
Explanation:
The testes are the male sex glands, because they produce male sex cells (sperm) and male sex hormones (testosterone). Their female equivalent would be the ovaries, which produce the ovules and the various female sex hormones.
The cell membrane is selectively permeable, allowing only certain substances to pass through. Passive transport is a way that small molecules or ions move across the cell membrane without input of energy by the cell. The three main kinds of passive transport are diffusion, osmosis, and facilitated diffusion
