B13 Reproduction Flashcards
what is asexual reproduction
involves one individual and the offspring is identical to the parent. there is no fusion of gametes or mixing of genetic information
what is sexual reproduction
involves the joining of male and female gametes producing genetic variation in the offspring
how many parents are in asexual production
1
how many parents are in sexual production
2
what’s faster sexual or asexual reproduction
asexual
what type of cell division occurs in asexual reproduction
mitosis
what type of cell division is used in sexual reproduction
meiosis (then mitosis once formed)
what does homozygous mean
an individual with 2 identical alleles
BB bb
what is heterozygous
an individual with different alleles
Bb
what is a dominant allele
if one dominant allele is present then the phenotype is present even if there is only one dominant allele
what’s a recessive allele
the phenotype is only present if there are 2 recessive alleles
what is polydactyly
a inherited disorder that causes the person with it to have an extra finger
is polydactyly caused by a dominant or recessive allele
dominant
what is cystic fibrosis
a genetic disorder causing mucus made by the body to be very thick and sticky.
causing organs like the lungs to become clogged up by the mucus and stop working properly.
is cystic fibrosis caused by a dominant or recessive allele
recessive
