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.
Estrogens are hormones that are play important roles in the reproductive system.
<h3>What are the roles played by estrogen?</h3>
The environmental estrogen introduced to the male cells has the ability to recognise the binding sites of the receptors on the male cells.
They are able to attach the the cell membranes by its ability to bind to the cell receptors.
When the binding occurs, there would be a conformational change within the cell leading to:
- modulation of protein synthesis and
- development of the female secondary reproductive characteristics.

Answer:
Explanation:There are however some important differences between the two: Elastic cartilage has less matrix that hyaline cartilage, this matrix also being infused with elastic fibers. ... Elastic cartilage contains more and larger chondrocytes than the hyaline cartilage. They are more closely packed and only one chondrocyte per lacuna.
