If humans have 46 chromosomes in each of their body cells, how many chromosomes would you expect to find in an egg cell? A triploid cell in humans would have how many chromosomes? If a human gamete possessing one extra chromosome participates in fertilization with a normal human...
How many sex chromosomes are present in a human body cell? How many chromosomes does each human gamete contain? a) 92 b) 46 c) 16 d) 23 If humans have 46 chromosomes in each of their body cells, how many chromosomes would you expect to find in a sperm cell?
For the fruit fly, the diploid number is8, which can be written as 2N = 8, where N represents twice the number of chromosomes in a sperm or egg cell. Some cells contain only a single set of chromosomes, and therefore a single set of genes. How many chromosomes are there in fruit fly?
Dogs have 39 pairs, and some plants have as many as 100. Chromosomes come in pairs. Each chromosome is a tightly packed strand of DNA. There are two strands of DNA joined together at the centromere to form an X-shaped structure. One strand comes from the mother and one from the father...
In diploid cells,one set of chromosomes is inherited from the individual's mother, while the second is inherited from the father. Humans have 46 chromosomes in each diploid cell. Among those, there are two sex-determining chromosomes, and 22 pairs of autosomal, or non-sex, chromosomes. ...

How many chromosomes will each gamete have? Explain. What is one genetic disease that can result from nondisjunction? A) Based on chromosome nondisjunction, briefly explain why the sequence of meiosis in human females could lead t...
Until recently we had a poor understanding of the effect of aging on male fertility. It was assumed that male fertility was relatively immortal because so many elderly men have been able to impregnate their wives. However, there has been previous crude data showing a relative decrease ...
One of the main objectives of QTL analysis has been to understand whether the phenotypic differences are due to some loci with reasonably large effects, or to many loci, but each with small effects. It seems that a substantial proportion of the phenotypic variation in many quantitative characteris...
