Answer:
approximately 200
Explanation:
From the question, we have
probability of red = 0.75
Probability of white = 0.25
We are required to find the probability of 6 red + 2 white plants offspring and after we do we multiply it by 640
We will solve this using the binomial theorem method
(a+b)⁸ = a⁸+8a⁷b+28a⁶b²+56a⁵b³+70a⁴b⁴+56a³b⁵+28a²b⁶+8a¹b⁷+b⁸
The required probability is 28a⁶b²
a = 0.75
b = 0.25
= 28 x 0.75⁶ x 0.25² x 640
= 28 x 0.178 x 0.0625 x 640
= 199.36
Which is approximately 200 crosses would be needed
Positive selection tests to see if the TCR of a T-lymphocyte can recognize and bind to an MHC molecule.
<h3>What is a T-lymphocyte?</h3>
A T-lymphocyte is a special type of immune cell that is generated inside the bone marrow.
The T-cell receptor (abbreviated as TCR) is a protein located on these immune T lymphocytes.
In conclusion, Positive selection identifies if the TCR of a T-lymphocyte can recognize and bind to an MHC molecule.
