why can we say that a single human zygote contains 1 ﻿out of 64
 ﻿trillion possible chorsmosome combinations

Accepted Answer

∻Answer∻ ⚹ A single human zygote contains 1 out of 64 trillion possible chromosome combinations due to the random assortment of chromosomes during meiosis and the combination of genetic material from two parents. ⚹ ∻Solution∻ ‖ a ⋮ Meiosis: During meiosis, homologous chromosomes are randomly assorted into gametes. Each parent produces gametes with $2^{23}$ possible combinations of chromosomes. ‖‖ b ⋮ Fertilization: When a sperm and an egg combine during fertilization, the total number of possible combinations is $2^{23} imes 2^{23}$, which equals approximately 64 trillion. ‖ ∻Key Concept∻ ⚹ Genetic variation in meiosis ⚹ ∻Explanation∻ ⚹ The random assortment of chromosomes during meiosis and the combination of genetic material from two parents result in a vast number of possible chromosome combinations in a zygote. ⚹◊How many possible chromosome combinations can be formed in a human zygote with 23 pairs of chromosomes?⍭ Generate me a similar question◊
