Question

fill in the blanks about Meiosis
Meiosis I:
1) Starts with _____________ cell
2) Results in two cells that are genetically _________________ from each other and parent cell
3) PROPHASE I – _________________________ (chromatids exchange genetic material)

Answer 1

1.Starts with sex cells(reproductive) or gametes during fertilisation
2.Results in two cells that are genetically different from each other and parent cell
3.PROPHASE I homologus chromosomes pair up and crossing over occurs (chromatids exchange genetic material)

Answer 2

not 2 sure bout #2!

Answer 3

@agentscape great thank you

Answer 4

welcome!!

Answer 5

@agentscape fill in the blank about Meiosis II:
Starts with two genetically different diploid cell produced through Meiosis I
1) Results in four __________________ cells (gametes)

Gametes used in sexual reproduction which add to biodiversity and allows for adaptations
• Asexual reproduction is faster but limits diversity and adaptability of organisms

Answer 6

haploid cells

Answer 7

@agentscape fill in the blanks about Heredity Patterns
Things to remember:
1) ______ copies of each allele (one from mom and one from dad)
2) Genotype – the letters used to represent the alleles (ex: ____, RR, ff)
• Phenotype – the physical appearance of a trait (ex: flower color, hair texture)
• Heterozygous – one dominant and one recessive trait. Dominant trait is expressed (ex: Dd)
• Homozygous – both traits are dominant OR both traits are recessive (ex: RR or rr)

3) REMEMBER: In order for a recessive trait to be expressed there must be _____ copies of the recessive allele (ex: rr or tt)!

Answer 8

sexual reproduction also allows for variation in offspring, sometimes with stronger genes

Answer 9

1) DNA replication
2)

Answer 10

2)?
3)?

Answer 11

@agentscape fill in the blank about Incomplete Dominance:
1) Form of inheritance in which the phenotype of two different alleles for a gene is _____________
