GE 02-48 MEIOTIC SEGREGATION AND GENE COMBINATION

Sexual cells are also called
1. gametes
2. somatic cells
3. body cells
Gametes are
1. haploid
2. diploid
3. monadoid
A gamete contains
1. one set of chromosomes
2. two sets of chromosomes
Monohybridism - genotype is Aa:
1. By segregation two types of gametes A and a can develop with the same probability
2. Only one type of gametes A can develop by segregation
3. Only one type of gametes A can develop by segregation
Dihybridism - genotype is AaBb
1. by segregation four types of gametes AB, Ab, aB, ab can develop with the same probability
2. by segregation two types of gametes AB, ab can develop with the same probability
3. by segregation three types of gametes AB, Ab, ab can develop with the same probability
If the letter n means the number of chromosome pairs, then it stands good:
1. The number of the gametes types, which develop with the same probability by meiotic segregation, is 2 square n
2. The number of the gametes types, which develop with the same probability by meiotic segregation, is 3 square n
3. The number of the gametes types, which develop with the same probability by meiotic segregation, is 8 square n
It stands good in Genetics:
1. genes are located on chromosomes
2. chromosomes are located on genes
In the human gametocyte of the 1st order there are
1. 23 pairs of chromosomes
2. 23 chromosomes
Trihybridism - genotype is AaBbCc:
1. Eight types of gametes can develop by segregation with the same probability.
2. Four types of gametes can develop by segregation with the same probability.
3. Twelve types of gametes can develop by segregation with the same probability.
Ametic splitting is the base for
1. Mendel´s laws
2. Morgan´s laws
