1.True or false? Gametogenesis is the same as meiosis?
Lostsunrise [7]

1. False. They are similar, though.

meiosis- A kind of cell division involving having the chromosome number. It is responsible for genetic recombination.

Gametogenesis- It's the process when gametes or germ cells are produced in an organism. They undergo meiosis to form gametes.

2. Spermatogenesis- happens in the testes of males. 4 gametes are produced. Spermatogenesis involves a metamorphosis stage called spermiogenesis. Spermatogenesis produces small, motile spermatozoa

Oogenesis- takes place in the ovary in a female. 1 gamete produced. in oogenesis there is no metamorphosis stage. In oogenesis the ovum is spherical, and isn't motile and is bigger with more food reserves and cytoplasm.

3. Because The one egg cell that results from meiosis contains most of the cytoplasm, nutrients, and organelles.

Identify the phenotypes for the offspring of a parent with the genotype IBi and a parent with the genotype IAIA. type O type A,
agasfer [191]
 <span>I is dominant, i is recessive. The A's and B's are just show which allele I is. When there is just one dominant allele, it masks the recessive in blood typing. Remember IA and IB are codominant. 

O is always ii 
A is IAi (heterozygous) or IAIA (homozygous) 
B is IBi (heterozygous) or IBIB (homozygous) 
AB is always IAIB 

Remember: You get one allele from each parent! 

1. Father must be ii, mother must be ii, so all children must be ii. 

2. Father is IAIA (the homozygous one), the mother is IBIB, so the only possibility for the children is IAIB, because you get one allele from the father and one from the mother. 

3. Father is IAi, mother is IBi, so the children can be any of the blood types, because they can have all the combinations of genotypes. 

4. Father is ii, mother is IAIB. Children can only be IAi or IBi. 

5. Father is IAIB, mother is IAIB. Children can be IAIA, IBIB, or IAIB. 

Example of Punnett square: 
3. Father is type A, heterozygous, mother is type B, heterozygous 
Father must be IAi (heterozygous) 
Mother must be IBi (heterozygous) 

_______IA ____ i 

IB____ IBIA____IBi 

i _____ IAi______ii 

Sorry, that was difficult on here, hope it's understandable. 
The father's alleles run across the top, the mother's are on the side, you follow to where they meet to find the possibilities for the children. IBIA (AB blood type), IBi (B), IAi (A), and ii (O) are the possibilities in this case. 

Hope that helps!</span>
